Email can be a wonderful tool for delivering feedback to students. Once a basic understanding of feedback’s role in learning has been established, one can begin to focus on how best to take advantage of the pedagogical functions of the com- munication medium. There is little doubt that email is changing how we commu- nicate and learn. For example, in an investigation of the effectiveness of email as a communication and instructional aid between instructors and students, Yu and Yu (2002) found “empirical evidence supporting the usefulness of e-mail as a prom- ising aid to promote student cognitive growth pertaining to computer knowledge and skills”.

Tao and Boulware (2002) suggest that email communication benefits teachers by “identif[ing] instructional focus and tak[ing] advantage of instructional moments to fit the developmental needs of their students in authentic situations”. They also find that email motivates learners, encourages authentic communication and cre- ates new learning opportunities.

Thank you, Dr Tikoo, for a nice introduction and thanks to ATPBR for inviting me to deliver this WebCon. I would like to start with a small introduction that this particular talk is structured as a general introduction to thrips and thrips-transmitted viruses. There is a bit of interest in everyone with regard to the black thrips which has caused havoc in the last couple of years. The topic has significant importance to plant breeders with regard to the new invasive Western Flower thrips, one of the most dreaded thrips, across the globe and the problems associated with the management of resistance in protected cultivation, and, finally how do we go about with regard to the entire management of the thrips and thrips-transmitted virus problems.

Introduction

India’s food problem dates back prior to independence. In the beginning, India’s food problem was one of scarcity, shortage of rice after the separation of Myanmar (Burma) from India in 1937 and shortage of wheat, also after the partition of the country in 1947. Initially, the major concern was to increase the domestic supplies either through increased production or through imports or through both. In the second half of the 1950s and during the 1960s the major concern was shifted to control of food grains prices. The Government of India entered into an agreement in 1956 with the USA known as PL 480 agreement for the import of rice and wheat. The Government found the PL 480 food imports a good tool to stabilize food prices in the country. Infact, PL 480 imports were the basis of our agricultural and industrial development. The frequent occurrence of flood and drought, food shortage resulted famine in several corners of the country during pre-independence period and even after independence.

Mechanization of agriculture is essential for optimal utilization of vital inputs for crop production system such as soil, water, seed, fertilizer, pesticide and labour force leading to higher productivity and reduced cost of production for greater profitability. Thus with the support of mechanization, the agrarian sector as an enterprise needs to become sustainable and economically competitive which coincides with the objectives of the Integrated farming System concept. Mechanization also imparts capacity to the farmers to carry out farm operations with dignity, comfort and freedom from drudgery, making the farming agreeable vocation for educated rural youth as well. It helps the farmers to achieve timeliness and precisely meter and apply costly input for better efficacy and achieve higher productivity with reduced application of inputs. Small and marginal farmers now make use of high capacity agricultural machines on custom hire basis to enjoy the economic benefits. As such, the broad subject of agriculture can be understood as production agriculture, which takes care the field operations in the crop production system for higher productivity and post production agriculture, better known as post harvest technology which looks for reducing the loss of produce and value addition for economic gains. The IFS outlines the need of sustainability for farmers with limited resources of land, water and economy while mechanization aims at maximizing the profitability in agricultural system with a commercial attitude. Since the availability of labour force during peak hours of need and hike in wage very often creates hindrance in production and post production agriculture, mechanization can be the right answer to harness the benefits of IFS approach.

Commercialization is essential for agricultural development, which, amongst other things, entails mechanization of agriculture to reduce the cost of production and to increase the yield of crops. In some instances, agricultural commercialization may take place even without mechanization. However, due to the ever increasing agricultural labor scarcity in developing countries, an extensive scale agricultural commercialization may not be possible without mechanization.

The various farm operations involved in crop production system are land leveling, tillage for seed bed preparation, sowing and planting, weeding and interculture, spraying, harvesting and threshing. The mechanization of all these operation has been appreciated by the farmers which are discussed in the following paragraphs.

3.1. Concept of farm mechanization

To apply the principles of engineering and technology to do the agricultural operations in a better way to increase crop yield.

Development, application and management of all mechanical aids for field operation, water control, material handling, storage and processing.

Mechanical aids include hand tools, animal drawn implements, power tillers, tractors, engines, electric motors, grain processing and hauling equipments.

Introduction

Rice (Oryza sativa), the staple food of more than half of the population of the world, is an important target to provide food security and livelihoods for millions. As a major producer and exporter of rice in the world, India reportedly produces around 152.60 MT tonnes of rice per year. When cereal crops are harvested, it is estimated that half of the process ends with agricultural waste or crop residue as straw. It is a non-edible product, often left in the field after harvesting. Traditionally, paddy straw was seen as a versatile by-product of rice cultivation because it was used in many ways including fodder for livestock and as a building material. However, the increase in productivity and area under cultivation of rice has led to a huge production of rice straw. Moreover, mechanization decreased the animal dependency and hence the feed requirement. So the most effective way of disposing of the residue is seen as burning of biomass in the paddy field. It is important to mention that open field burning is a widely practiced method all over the world however its intensity varies. For instance (National Conference, 2017) estimated that less than a quarter of rice straw is probably burnt in India compared to around half in Thailand whereas the entire residue is burnt in the Philippines. Taking farmers view into account, burning is not only a cost-effective method but it acts as an effective pest control procedure Shukla et al (2005). The short term effects of burning seems more desirable than those from soil incorporation due to the immobilization of inorganic nitrogen which occurs in the latter and can adversely affect productivity in the short term (Singh and Singh, 2001). Also, it helps to reduce diseases that may occur due to reinjection from inoculums in the straw biomass Haysa et al. (2005).The burning of rice crop residue causes atmospheric pollution by emitting trace gases which forms ‘Black Cloud’ adversely affects human health as well as environment. The air pollutants are also a hazard to people’s health particularly to those within local proximity to paddy areas. It is clear from Table 1 that crop residue is a good source of nutrients and important component for the stability of agricultural ecosystems. About 40% of the N, 30-35% of the P, 80-85% of the K and 40-50% of the S absorbed by rice remain in the vegetative parts at maturity.

Labour is one of the biggest input costs for vegetable growers. Vegetable farming is labor intensive and time consuming. Frequently, it is associated with low yield and poor quality production. The constraints are high labor requirements for land clearing, ploughing, bed forming, mulch laying, seeding, transplanting, harvesting and transporting. Mechanization is interjection of improved tools, implements, machines and other equipments between man and materials (soil, water, environment, seed, fertilizer, pesticides, growth regulators, irrigation water, agricultural produce and by-products such as fruits, vegetables, and seeds, etc.)

Sowing of Seed: It is a process of planting seeds of crops in well prepared or no till field or nursery beds/pots for raising crops in following methods:

Methods of Sowing: The sowing method is determined by the crop to be sown and resources on the disposal of farmer. There are 6 sowing methods which differ in their merits, demerits and adoption. Those are:

1.Broad casting

2.Broad or Line sowing

3.Dibbling

4.Transplanting

5.Planting

6.Putting seeds behind the plough.

Traditional media channels have served as the backbone of agricultural communication in India for decades, playing a crucial role in disseminating information about farming practices, government schemes, and technological innovations to rural communities. These conventional platforms, including radio, television, print media, and community-based communication methods, continue to remain relevant and effective for promoting natural farming practices, despite the emergence of digital technologies. Understanding the strengths, limitations, and optimal utilization strategies for traditional media is essential for developing comprehensive communication programs that can reach diverse farming populations across various geographical and socio economic contexts. Radio broadcasting represents one of the most successful and enduring traditional media platforms for agricultural extension in India. All India Radio (AIR) has been actively playing a unique role in bridging the digital divide and supporting agricultural extension programmes in India since the experiment in 1952-53 with ‘An Indian Experiment in Farm Radio Forums’ at Poona (now Pune). The effectiveness of radio stems from its accessibility, affordability, and ability to reach illiterate farmers who may face barriers with text-based information sources. Radio programs dedicated to agriculture have evolved significantly from simple one-way

One of the most essential factors governing the growth and morphogenesis of plant tissues in culture is the composition of the culture medium. The basic nutrient requirements of cultured plant cells are very similar to those of whole plants. The basic nutritional requirements of cultured plant cells as well as plants are very similar. However, the nutritional composition varies according to the cells, tissues, organs and protoplasts and also with respect to particular plant species.  The appropriate composition of the medium largely determines the success of the culture. A wide variety of salt mixtures  have been reported in various media. A nutrient medium is defined by its mineral salt composition, carbon source, vitamins, plant growth regulators (PGR) and other organic supplements. When referring to a particular medium, the intention is to identify only the salt composition unless otherwise specified. Any number and concentration of amino acids, vitamins, growth regulators and organic supplements can be added in an infinite variety of compositions to a given salt composition in order to achieve the desired product.

Nurserymen and propagators propagate different types of horticulture plants with seeds, cuttings, and other methods. Regardless of the medium used, an ideal medium should have the following characteristics:

1. The medium should be sufficient firm and dense to told seed or cutting or layer firmly in place during germination or rooting.
2. The volume of the medium should remain constant upon drying or wetting.
3. This medium should be able to hold and deliver an adequate amount of moisture to the seeds, cuttings or layers.

6.1 Role of Media in Democracy: Introduction

The media is the fourth pillar of democracy. The media has a critical role in creating a democratic culture that transcends the political system and gradually enters the general public's consciousness. Voters rely on the political information provided by the media to make their selections. They facilitate discussion and help discover issues facing our society.

Importance

After tieing the ring with bamboo splint and padding the ring with jute and cotton .bending the lower half of the ring upto more than 45 degree angle is highly essential because of placement of the fractured limb within the ring of Thomas splint comfortably, so as to the flow of blood circulation in fractured limb uninterruptedly.

Medication Errors: Definition
Medication errors are defined as preventable events that may cause or lead to inappropriate medication use or patient harm while the medication is under the control of a healthcare professional, patient, or consumer. These errors can occur at any stage of the medication use process, including prescribing, transcribing, dispensing, administering, and monitoring.
Key Aspects of Medication Errors
1. Preventability: The term “medication error” emphasizes that these events are preventable, highlighting the importance of systems and processes designed to minimize risks associated with medication use.
2. Broad Scope: Medication errors encompass a wide range of issues, including:
• Prescribing Errors: Mistakes made during the prescribing process, such as incorrect dosage or inappropriate medication selection.
• Transcribing Errors: Errors that occur when prescriptions are written down or entered into a system.
• Dispensing Errors: Mistakes made by pharmacists or pharmacy technicians when preparing medications for administration.
• Administration Errors: Errors that occur when a medication is given to a patient, such as administering the wrong drug or incorrect dosage.
• Monitoring Errors: Failures in monitoring the effects of medications on patients, which can lead to adverse outcomes.
3. Potential for Harm: While not all medication errors result in harm, many have the potential to cause significant adverse drug events (ADEs). An ADE is defined as any injury resulting from medical intervention related to a drug.
Types of Medication Errors
Medication errors are preventable events that can lead to inappropriate medication use or patient harm. They can occur at any stage of the medication use process, from prescribing to administration. Understanding the various types of medication errors is essential for healthcare providers to implement strategies that enhance patient safety. Below is a detailed overview of the different types of medication errors.

Medication refers to administration of drugs. The route, dose and frequency of the drugs administration is most important in providing health care and welfare of the animals. Wide range of body size and their weight in animals and rearing practice makes the treatment and drug administration strategies a bit complex. Because of this complexity wide range of drug formulary and drug delivery strategies has been developed in animals for health care. Route of drug administration varies from oral administration, parenteral administration to local application on skin and mucus membrane. Similarly forms of the drugs varies from liquids, semisolids to solids for oral administration; from clear solution, suspension, emulsion to powder for parenteral administration; and from powder, cream, paste, suspension, ointment, solutions to emulsifiable concentrates for local application. Oral Administration of Drugs All three forms of drugs viz. liquids (solution, emulsion, suspension), semisolids (paste), and solids

The relationship between man and plant resources of his surroundings is intimate. Of the 350 tribes inhabiting different parts of India, about 171 dwell in Himalayan region. The inhabitants of the mountain areas use native flora for food, fodder, fiber, fuel, timber and for health care of both human beings and their livestock. These plant resources, particularly medicinal and aromatic plants (MAPs), not only meet their health care needs but also support their livelihood. Recently the demand of MAPs has transformed from local and traditional needs to global needs. This has adversely affected availability and quality of raw material as also livelihood and health options of the local people. Most of the raw materials are gathered from the forests, and only a few plants are under cultivation. To avoid rampant exploitation of MAPs from nature, there is an urgent need to establish procedures for their cultivation and organized marketing. The present article deals with strategies and actions to protect livelihood options of the indigenous communities inhabiting mountain areas in western Himalaya as well as promote sustainable utilization of MAPs through scientific and technological interventions.

Introduction

India and China are two major Medicinal and Aromatic Plants (MAPs) producing countries, providing 40% of the global diversity and availability of rare species. The Ministry of Environment and Forests, Government of India has identified and documented over 9,000 species of medicinal plants that are significant for the pharmaceutical industry (AICRPE 1996). Of these, 2,000 to 2,300 species are used in traditional medicines while at least 150 species are used commercially on a large scale (EXIM Bank 1997).

Horticultural medicinal plants

Throughout recorded history, people have held medicinal plants in high regard due to the many health benefits they provide. Natural cures abound among these botanical marvels, and they may alleviate a wide range of health problems. The wide variety of bioactive substances found in them has been used to create pharmaceutical medications and alternative treatments, suggesting that they may have curative properties. Medicinal plants, such as aloe vera and turmeric, offer a wide range of uses, including pain relief, the treatment of chronic diseases, and general health improvement. A newfound respect for traditional herbal medicine’s knowledge and the need of preserving these priceless resources has emerged in recent years, as contemporary medicine investigates the plants’ unrealized potential.

Introduction
India, renowned for its rich biodiversity and ancient tradition of Ayurveda, is home to an astonishing array of medicinal and aromatic plants. These plants, harboring bioactive compounds such as alkaloids, glycosides, terpenes, and flavonoids, have been harnessed for centuries to prevent, diagnose, and treat various health ailments. Medicinal plants, utilizing parts like leaves, roots, stems, or seeds, offer natural remedies for wellness. Meanwhile, aromatic plants, rich in fragrant volatile oils, are the cornerstone of essential oils, aromatherapy, and perfumery. A Legacy of Healing: History of Medicinal and Aromatic Plant Cultivation in India

Ancient India (3000 BCE - 500 CE)
Ayurveda's origins: Ayurveda, the traditional Indian system of medicine,
emerged around 3000 BCE, emphasizing the use of medicinal plants.
Vedic period (1500 BCE - 500 BCE)
• Ayurvedic texts like the Rigveda, Yajurveda, and Atharvaveda documented medicinal plant uses.
• Charaka Samhita and Sushruta Samhita (400 BCE - 200 CE): These seminal texts systematically described medicinal plant properties and uses.

Introduction

Medicinal and aromatic plants constitute a major segment of the flora, which provides raw materials for use in the pharmaceuticals, cosmetics, and drug industries. The indigenous systems of medicines, developed in India for centuries, make use of many medicinal herbs. These systems include Ayurveda, Siddha, Unani, and many other indigenous practices. More than 9,000 native plants have established and recorded curative properties and about 1500 species are known for their aroma and flavour. In one of the studies by the World Health Organisation, it is estimated that 80 per cent of the population of developing countries relies on traditional plant based medicines for their health requirements (WHO 1991). Even in many of the modern medicines, the basic composition is derived from medicinal plants and these have become acceptable medicines for many reasons that include easy availability, least side effects, low prices, environmental friendliness and lasting curative property. India and China are the two major producing countries, having 40 per cent of the global biodiversity and availability of rare species. These are well known as the home of medicinal and aromatic crops that constitute a segment of the flora, and provide raw materials to the pharmaceutical, cosmetic, fragrance, flavour etc. industries.

1. GENERAL INFORMATION!

Major constraint of medicinal plants: Lack of genuine planting material.

Maximum number of medicinal plants belong to family Asteraceae.

Maximum demand in world market: 1. Senna leaves 2. Isabgol seeds 3. Cassia tora seeds.

India is largest producer of 1. Kewada oil 2. Senna 3. Davana oil 4. Isabgol.

India is 2^nd largest producer of 1. Opium latex 2. Jasmine concrete 3. Tuberose concrete

India is 3^rd largest exporter of periwinkle.

Thailand is largest exporter of sarpagandha leaves.

China is largest producer of 1. Geranium oil 2. Citronella oil.

A large number of people in developing countries have traditionally depends on products derived from plants, especially from forests, for curing human and livestock ailments. Additionally, several aromatic plants are popular for domestic and commercial uses. Collectively they are called medicinal and aromatic plants (MAPs). About 12.5% of the 4,22,000 plant species documented worldwide are reported to have medicinal values. With dwindling supplies from natural sources and increasing global demand, the medicinal and aromatic plants, will need to be cultivated to ensure their regular supply for processing and value added products.

The term “Medicinal and Aromatic plants” generally denotes those non-aromatic and aromatic plants, which are used for medicinal, perfumery, dye and cosmetic purposes. They are rich in secondary metabolites and are potential sources of drugs. Generally the whole plant roots, stem, bark, leaves, flowers, fruits, gums and oleoresins, etc. are used.

India has been considered as treasure house of valuable medicinal and aromatic plant species. Ministry of Environment and Forests have identified and documented over 9500 plant species considering their importance in the pharmaceutical industry. In the present context of ‘back to nature’ in health care, it is relevant that these valuable plant species are not only preserved but also their cultivation developed in order to meet the entire demand of the domestic industries as also to exploit the bright prospect for export. Shift from collection to cultivation of medicinal & aromatic plants will also ensure purity, authenticity and sustainable supply of raw materials required for herbal drugs, including polyherbals.

Medicinal plants are non-food non-plantation crops.

These are rich in secondary metabolites viz. alkaloids, glycosides, coumarins, flavonoides and steroids, etc.

Union government of India has started a project on 'Traditional Knowledge Digital Library' under which it is documenting all Ayurvedic formulations in a digital form to avert patent threats from companies in the developed world

1. Introduction

There are a large number of indigenous rice varieties in India, which are still grown by the tribal people and small farmers of the remote areas where the modern agricultural practices, sufficient foods as well as healthcare systems are a dream. Nature has provided them some alternative ways. They have different indigenous rice varieties with its nutritional and medicinal values. Until recently, rice was considered only a starchy food and a source of carbohydrates and some amount of protein. Rice protein, though small in amount, is of high nutritional value (Chaudhary and Tran, 2001). It has extensive curative properties known from the ancient days. In fact, specific rice varieties with medicinal properties were cultivated and used in the treatment of some ailments in different counties of South East Asia.

During recent times, both at national level and international levels, the land races are being preserved in the gene banks. The scientists said that they were also checking these land races for some such characteristics which were not available in the existing varieties so as to incorporate the same in the present varieties (Sultan and Subba Rao, 2013). Traditional varieties are experiencing an increasing trend among consumers, due to their incredible health benefits for example the traditional varieties possess higher amount of glutamic acid, fiber and vitamins. Some people also credit traditional varieties with other health benefits, such as giving sensations of cooling in the body, improves vocal clarity, eyesight, fertility and mitigating rashes (Caius, 1999).

ABSTRACT

Artemisia annua L. is known for the content of anti-malarial drug, artemisinin. It is widely distributed in subtropical, temperate and subtropical zones worldwide and traditionally used for the treatment of various ailments. Artemisinin has been the frontline treatment since the late 1990s and saved countless lives, especially among the world’s poorest children. The major chemical constituents of Artemisia annua L. are sesquiterpenoids and some phenolics. The essential oil of Artemisia contains artemisia ketone, camphor, caryophyllene oxide, 1,8- cineole and -pinene, and these essential oils constituents are known for their medicinal properties.Artemisinin was discovered in 1971 bya Chinese Medicinal Chemist Youyou Tu (Nobel Prize in 2015). As the demand for artemisinin remains high worldwide, exploring the chemical and the genetic variation especially knowledge, about its mechanisms for high-yielding would be more important. The plant extract is also known for other biological activities such as anti- hypertensive, anti-microbial, immuniosuppresive, and antiparasitic activities. To increase the production of artemisinin and to investigate the effect of climate change on artemisinin content will be the major research area in future from Artemisia genus. Exploring the alternative resources such as microbial production and semisynthetic approaches from other easily available natural molecules would be of high demand. Some other molecules from Artemisia should also be focused for the future development of man kind and in drug discovery science. An overview of present status of medicinal applications, phytochemistry, and future perspectives for the research possibilities on the active ingredient Artemisinin from A. annua is discussed in this chapter.

1. Introduction

During the last decade, considerable attention has been focused on the involvement of oxygen free radical (OFR) in various diseases. Molecular oxygen, while providing an efficient energy from ingested food, results in free radical and peroxide by-products, which have high intrinsic toxicity. Numerous physiological processes in living organisms occasionally produce free radicals, reactive nitrogen species (RNS) and reactive oxygen species (ROS) as by-products. Their broad ranges of effects in biological systems have drawn the attention of many experimental works. ROS have been implicated in the pathophysiology of several clinical disorders, including ischemia, reperfusion injury, myocardial infarction, rheumatoid arthritis, neurodegenerative, atherosclerosis, acute hypertension, hemorrhagic shock and diabetes mellitus (Hemnani and Parihar, 1998).

Oxidative stress occurs in a cell or tissue when the concentration of reactive oxygen species (ROS) generated exceeds the antioxidant capability of the cell (Simic and Jovanovic, 1986). Although humans and other organisms possess antioxidant defense and repair systems to protect against oxidative damage, these systems are insufficient under certain conditions to prevent the damage totally (Chang and Miles, 1982). Hence, the oxygen free radicals mediated damage to protein, DNA and other biomolecules accumulates during the lifetime of organisms. Many synthetic antioxidant components exhibited toxic or mutagenic effects that have directed the attention to the naturally occurring antioxidants in recent years. A multitude of natural antioxidants have already been isolated from different plant materials such as oilseeds, cereal crops, vegetables, fruits, leaves, roots, spices and herbs (Ramarathnam et al., 1995).

ABSTRACT

Our country is well known for developing into rich and ancient traditional system of medicines based on plants. For centuries, these ancient cultures and professional practicing on traditional system viz. Ayurveda, Unani and Siddha could remain in house hold and pass through generations to generation. India is being a developing country, of late uses bioactive natural products (secondary metabolites) using in vitro culture technology of the medicinal plant species. Recently, commercial utilization of these compounds using modern techniques is in good progress. The developed western affluent world has to now depend on these compounds mostly in drug and pharmaceutical industry in recent years. Orchids as medicinal herbs, details on plant medicinal potentialities, traditional medicinal systems viz. Ayurveda, Unani and Siddha have been described.

Abstract

Since the beginning of the civilization, medicinal plants have been used to prevent and treat various ailments. At present, most of the pharmaceutical/ nutraceutical industries highly depend on wild medicinal plants for the supply of raw materials for extraction of bioactive compounds. As medicinal plants receive increased scientific and commercial attention, there is increasing pressure on the wild medicinal plant populations.

Introduction

Medicinal plants are considered as rich ingredients resources which may be utilized in medicines development pharmacopoeia, non-pharmacopoeia or synthetic industry. Apart from any region, these plants play a critical role within the development of human cultures around the whole world. Plant is a crucial source of drugs and plays a key role in world health. Medicinal herbs or plants are known to be a critical potential source of therapeutics or curative aids. The utilization of medicinal plants has attained a commanding role in health system all over the place the planet. This involves the utilization of medicinal plants not just for the treatment of diseases but also as potential material for maintaining healthiness and conditions. Many countries within the world, that is, two-third of the world’s population depends on herbal medicines for primary health care. The explanations for this are often due to their better cultural acceptability, better compatibility and adaptableness with the physical body poses lesser side effects. Evidently, records showed that most of the used drugs contain plant extracts. Some are containing active ingredients (bioactive components or substances) obtained from plants. Through recent researches, it revealed that plant-derived drugs were mostly discovered from the study of curative, therapeutic, traditional cures and above all the folks knowledge of indigenous people and a few of those claims and believe of individuals are irreplaceable despite the recent advancement in science and technology. A number of the drugs believed to be obtained from plants are aspirin, atropine, artimesinin, colchicine, digoxin, ephedrine, morphine, physostigmine, pilocarpine, quinine, guanidine, reserving, taxol, tubocurarine, vincristine and vinblastine. The importance of medicinal plants can’t be taken lightly; therefore, it’ll be of significance to look at the characteristics and roles of photochemical in a number of the medicinal plants commonly utilized throughout the world.

Feed additives like antibiotics, hormones are successfully employed in chicken production along with basic minerals, vitamins, and nutrients. Because of worries about antibiotic residues in animal tissues and the resulting development of bacterial resistance, the use of antibiotics as growth promoters (AGP) in cattle was outlawed in 2005. Given the rising concerns about antibiotic use and its involvement in antibiotic resistance, the use of plant-based chemicals in animal feed has become essential. Phytogenic feed additives, which are made from plants and their secondary metabolites, are becoming more and more popular as a result of the search for sustainable farming methods.
These natural growth promoters are seen as alternatives to synthetic chemicals, which are often associated with adverse environmental and health impacts. The usage of plant additions, also known as phytobiotics, have existed since the beginning of time, when people and farm animals were treated and prevented with herbs. The unique qualities of herbs and plant additions were effectively utilised by the ancient Greek, Egyptian, Roman, and Chinese civilisations. Phytogenic feed additives offer multiple benefits for livestock, including enhancing growth, improving immunity, supporting digestion, and promoting
overall animal health. Water or alcohol extracts derived from plant additions, whether fresh or dried, fermented, or freeze-dried, can be used in poultry practices.

The therapeutic potential of plants and its parts has been explored since ancient times and has been used for the well being of humans as well as animals. In the era of emergence of multi drug resistant bacteria modern research aims to find out alternative therapeutic approaches preferably from herbal source to combat the infection. Medicinal plants owing to their antibacterial, antioxidant, anti inflammatory capabilities have been used against many bacterial infections in livestock and companion animals. Ethnoveterinary practices have been documented against bacterial diseases in animals like mastitis, colibacillosis, Salmonellosis, pyoderma, otitis externa, gastrointestinal infection, pneumonia and many others, some of which are enlisted below.
Bovine mastitis, predominantly a bacterial disease continues to threaten the dairy sector as it inflicts great economic losses to the dairy farmers. The disease caused by more than 200 species of bacteria is characterized by inflammation of the mammary gland with physical and chemical changes in the milk and pathological changes in the glandular tissue. There is a significant reduction in the milk yield and many times it’s accompanied with abnormalities in the udder, milk and the cow. In addition to this, milk from affected animals may harbor the organisms which are potentially pathogenic to humans. Use of antibiotics is a common practice to cure mastitis.

The control of external parasites and the pertinent disease vectors using chemicals is riddled with various issues and hence there is a huge demand for alternative approaches. Natural products, being a prominent resource for poor farmers, can majorly serve as a cheaper, environment friendly and sustainable alternative. Further, ethno-veterinary and traditional knowledge has provided a diverse array of plants, which need to be validated for their repellent, insecticidal and acaricidal activities to claim their effect against external parasites. Besides, phytochemical study of these therapeutic plants has progressively revealed the existence of a variety of bioactive components in these plant derived extracts, catering to their efficacy against external parasites.
External Parasites in Domestic Animals
External parasites, also known as ectoparasites are organisms that live on the surface of domestic animals, feeding on their blood or skin. Fleas, ticks, mites, lice and flies are among the most common external parasites. These parasites can cause significant health issues in animals including discomfort, skin irritation and even severe diseases. Infestations can lead to conditions such as dermatitis, anemia and secondary infections. Moreover, many external parasites are vectors for serious diseases that can affect both animals and humans. Hence, effective management of these parasites is essential to ensure
the health and well-being of domestic animals.

Introduction
Helminths are a group of internal parasites of animals and human beings that usually infest gastrointestinal tract that feed from the host which provides protection to the parasite. The infestation cause loss of blood and nutrients from the host, making it weak, and vulnerable to other infections. There can be injury to other organs due to the migration of different stages of the parasite, formation of cysts or secretion of toxins that can cause damage.
The heminths belong to two phyla including nemathelminthes which are round worms and Platyhelminthes that has flukes, and tapeworms. Nematodes are round worms who have a resistant cuticle and most of them have separate sexes with direct or indirect life cycle. The major nematodes include Ascarids, Strongyles, strongyloides, Trichostrongyles, Filarids, Trichuris etc. Tape worms have a flat body with a head or scolex, neck and strobili having proglottids. They are hermaphrodites and the proglottids contain reproductive organs. They require more than one host for completion of life cycle. The flukes are ususally leaf like , unsegmented and have suckers that help them to attach to the internal organs of the host. They also have a life cycle in more than one host.

Viral Diseases in Domestic Animals
Viral diseases significantly impact the health and productivity of domestic animals, including livestock and companion animals, leading to substantial economic and emotional costs. In livestock, diseases like Foot-and-Mouth Disease (FMD) and Peste des Petits Ruminants (PPR) cause severe production losses in terms of milk, meat, and wool. Similarly, in poultry, Newcastle disease and Avian Influenza outbreaks result in high mortality and disruptions to egg production. Among companion animals, viruses such as Canine Distemper and Feline Leukemia Virus (FeLV) lead to serious morbidity and reduced quality of life. Current control measures rely heavily on vaccination and biosecurity practices, but the lack of effective antiviral treatments, coupled with the emergence of drug-resistant strains, underscores the need
for novel therapeutic approaches. Medicinal plants with antiviral properties have garnered significant interest as sustainable and holistic solutions. Plantderived bioactive compounds offer a dual advantage of modulating immune responses and directly targeting viral pathogens, making them a promising area of research for the management of viral diseases in both livestock and pet animals.

Herbal galactagogues are medicinal plants used to stimulate, sustain, and boost milk production. Several plants known for their galactagogue activity are being used traditionally in many cultures to stimulate milk production in animals. However, there is a knowledge gap regarding the safety and efficacy of these medicinal plants. Moreover, the mechanism of action of the herbal constituents present in these plants is not yet elucidated. Although, many herbal galactagogues have been reported as safe in domestic animals and can be used as food supplements in the dairy industry. Nowadays, the use of plantderived supplements has increased in the dairy sector promoting a new trend of organic dairy farming. Traditional remedies being used for increasing milk production in animals often incorporate herbal treatments, mainly comprising
of the following important herbs [1-8]:

Introduction
Arthritis, a condition characterized by inflammation of the joints, is prevalent among livestock species, particularly in older animals or those subjected to intensive farming conditions. It results in pain, reduced mobility, and diminished productivity. Herbal plants with anti-inflammatory and analgesic qualities are being investigated as a result of the increased interest in natural therapies, even if treatments like non-steroidal anti-inflammatory medications (NSAIDs) and corticosteroids have been utilized to manage arthritis in livestock. This chapter addresses the use of herbal plants to treat arthritis in cattle, including
a summary of the best plant-based remedies, their modes of action, and the scientific data that backs them up.
Pathophysiology of Arthritis in Livestock
Arthritis in livestock is primarily caused by joint degeneration, trauma, infection, or autoimmune disorders. The inflammation of the synovial membrane leads to the discharge of cytokines that cause inflammation, which degrade cartilage and cause pain. The condition significantly impacts the animal’s ability to move, affecting their overall well-being and productivity. In farmed animals, arthritis can lead to decreased milk production, reduced growth rates, and compromised meat quality, thus representing a significant economic loss.

Cardiovascular System Disorders in Domestic Animals
Cardiovascular system disorders in domestic animals include a range ofM conditions that affect the heart (pericardium, myocardium, endocardium), veins, arteries and lymphatic vessels. Infectious disorders like Heartworms (Dirofilaria immitis, vegetative endocarditis in pigs, equine viral arteritis). Patency of the foramen ovale, interventricular foramena, patent ductus arteriosus, persistence of the right aortic arch, coarctation of the aorta, transposition of the aorta, congenital aneurysm, pulmonic stenosis, subaortic stenosis, ectopia cardis, acardia, and diplocardia are examples of congenital and developmental disorders that can result in these conditions. Traumatic disorders like Traumatic reticulopericarditis and cardiac failure. Degenerative diseases like fatty and hyaline degeneration. Inflammatory disorders like pericarditis,
myocarditis, endocarditis and phlebitis may also lead to cardiovascular system disorders. Some tumours associated with the cardiovascular system like rhabdomyosarcoma, fibroma and myxofibroma also cause cardiovascular system disorders.

Nervous system Disorders in Domestic Animals
Nervous system disorders in domestic animals encompass a range of conditions that affect the brain, peripheral nerves, and spinal cord. These disorders can result in a variety of clinical signs, depending on the area of the nervous system involved. Infectious disorders like rabies, canine distemper, toxoplasmosis, listeriosis. Congenital and developmental disorders like hydrocephalus, cerebellar hypoplasia and chiari-like malformation can cause these disorders. Traumatic and degenerative disorders like Intervertebral Disc Disease. Degenerative myelopathy, metabolic and toxic disorders like hepatic encephalopathy, hypocalcemia, lead poisoning, organophosphate toxicity, autoimmune and inflammatory disorders like meningitis and meningoencephalitis may also lead to nervous system disorders. Some tumours associated with nervous system like meningiomas and peripheral nerve sheathtumours also cause nervous system disorders.  

Introduction
Diabetes mellitus is a disease the related to metabolism of the body and malfunctioning of pancreas. Pancreas having alpha and beta cells where alpha cells produce enzymes needed for the digestion and beta cells mainly produce insulin. One important component that regulates blood glucose (sugar) levels and how it is delivered to the body’s cells is Insulin. The body’s cells run out of their primary energy source when insulin levels are low. Insulin voices the body’s cells to engross glucose from the bloodstream. Without an satisfactory amount of insulin glucose cannot invade the cells and so it accrues in the blood, triggering hyperglycemia (high blood sugar). In retort to this ostensible starvation, the body starts flouting down supplies of protein & fat for energy, producing weight loss contempt a ravening appetite. The body efforts to remove the extra glucose by micturating. To avoid thirst, the dog drinks more and more water. Type I increased diabetes mellitus outcomes from completeobliterat ion of the insulin-creating beta cells. In dogs, this is the most prevalent kind of diabetes. As the name implies, insulin injections are necessary to balance blood sugar in dogs with this kind of diabetes.

Medicinal Plants for Arsenic Toxicity
Name of the Condition- Nephrotoxicity
About the condition/Definition- Intoxication of arsenic (arsenite or arsenate) result in renal impairment which is marked by a significant increase in the levels of creatinine, urea, uric acid and decline in levels of plasma protein profile especially albumin level in body.
Etiology- Nephrotoxicity results from arsenic damages mitochondria, which results in the excessive production of reactive oxygen species (ROS), a decline in ATP, and a suppression of respiratory activities along with dramatic alterations in the incidence of cellular growth. There is acute inflammation and the development of tubular necrosis, which lowers the glomerular filtration rate (GFR).
Symptoms- Phosphaturia (Fanconi syndrome), aminoaciduria, proteinuria and glycosuria along with progressive drop of renal function.
Pathogenesis- Arsenic produces renal damage by reducing mitochondrial complex function and elevating cellular ROS levels which directly damages renal cells. Membrane lipid peroxidation and protein oxidation by ROS, which results in complete loss of membrane potential and mitochondrial swelling.
General treatment- Acute arsenic intoxication can be counter by using chelating agents like DMSA, DMPS and BAL, fluid therapy, forced dieresis & dialysis.

Introduction
The use of medicinal plants for the treatment of diseases is a practice that spans centuries. In recent years, there has been a growing interest in using herbal remedies for treating fungal infections in livestock and animals. Fungal infections, caused by pathogenic fungi such as Aspergillus, Candida, Dermatophytes, and Mucor, can lead to significant health issues in animals, affecting both domestic and wild species. These infections often manifest as skin diseases, respiratory illnesses, gastrointestinal problems, and systemic infections, and can even lead to death if left untreated. While antifungal drugs are commonly used to manage these infections, concerns about drug resistance, toxicity, and sustainability have encouraged the exploration of alternative therapeutic options, particularly herbal medicine.
This chapter explores the potential of medicinal plants used as antifungal agents in livestock and animals, highlighting their efficacy, safety, and practical applications.

Our digestive structure is not only just a food handle centre. It’s a foundation of fitness, moving everything from our immunity to mental well-being. A fit gut aids in the digesting and assimilation of nutrients supports a healthy and strong immunity, and helps in the effective elimination of waste. Asserting good gut fitness is critical because it can influence our whole body’s health, prevent chronic afflictions, and develop value of growth. Plants have been second-hand for curative purposes for thousands of years, and many up-todate cures are still coming from plant compounds. In this chapter, we will
study some commonly used medicinal plants used to treat common digestive system diseases, along with associated ethnomedicinal details.
1. Diarrohea
About the condition/Definition- Loose, watery and possibly more-frequent passage of stool is called diarrohea. Feeling of urgent need of frequent bowel movement in a day.
Etiology- A few causes include infections, diseases, and food intolerances. Rotavirus, norovirus, viral gastroenteritis; salmonella, E. coli; giardiasis, amoebiasis and food intolerance are few important causes of diarrohea.
Symptoms- The symptoms include a strong desire to have bowel movement and frequent loose, watery feces. Occasionally linked to cramps, bloating, thirst, nausea, and abdominal pain

Introduction:The phenomenon of reproduction is an important aspect, which needs special attention in livestock farming to achieve optimum productivity and increase the economic status of the farmers. Variousgynaecological problems like anestrus, repeat breeding, endometritis,  retention of placenta, etc reduce thereproductive performance in farm animals. Besides indirect reducing the milk yield, it also creates financial burden on the farmers due to high cost of therapeutic drugs prescribed for their treatment. The use of various hormonal preparations and antibiotics has been critical in treating these disorders inthe farm animals. However, herbal treatments render a holistic approach to manage the reproductive problems with minimalcost and no side effects.
1. Name of the condition: Anestrous
About the condition/definition: Anestrus is a reproductive cycle dysfunction in which an animal does not display the obvious symptoms of estrus. It is one of the major limiting factor in achieving better reproductive
performance in farm animals.
Etiology and pathogenesis: Expression of estrus is controlled by secretion of reproductive hormones. Any disturbance in their secretion due to the effect of either ofSeason, stress, uterine diseases, poor management techniques, inadequate nourishment, etc., delays the process.The animals with smooth non-functional ovary are said to true anestrous, whereas absence of estrus due to retained CL on ovary due to uterine pathology are false anestrous.

The kidney plays a role in controlling the volume of different bodily fluids, fluid osmolality, acid-base balance, toxin elimination, and different electrolyte concentrations. The glomerulus filters one-fifth of the volume of blood that enters the kidneys. Among the compounds that are reabsorbed include amino acids, salt, bicarbonate, glucose, and solute-free water. Among the chemicals that are released are ammonium, potassium, hydrogen, and uric acid. The kidneys maintain homeostasis, eliminate metabolic waste products like uric acid, urea, creatinine and ammonia, regulate extracellular fluid volume, blood pressure (via the rennin-angiotensin system) and controlling systemic pH (via regulation of H+ and HCO3- concentration).
Among various kidney diseases, especially chronic kidney disease (CKD) is a slow loss of kidney function in which, kidney dysfunction is present for more than three months. There are six progressive stages of CKD i.e. stages 1, 2, 3a, 3b, 4 and 5. The stages are based on the results of glomerular filtration rate (GFR) test (1). In stage 1 there is mild kidney damage, while in stage 5 kidneys lost their working capacity. Chronic kidney disease (CKD) is a worldwide health issue that is becoming more prevalent in both developed and developing nations. It typically affects adults. .

Respiratory tract disorders in domestic animals
The respiratory system is vital for efficient oxygen exchange, metabolic function, and overall health. Respiratory tract disorders in livestock speciesare among the most significant health challenges, leading to  economic losses in terms of reduced productivity, treatment costs, and mortality. Thesedisorders can affect the upper respiratory tract (URT), lower respiratory tract  (LRT), or both. Overview of common respiratory diseases in livestock, their aetiology, clinical manifestations, pathophysiology, diagnostic approaches, and management strategies are summarized as follows: -
1. Bovine Respiratory Disease Complex (BRDC)
? Species affected: Cattle
? Etiology: Multifactorial; involves viruses (Bovine herpesvirus-1, Bovine respiratory syncytial virus, Parainfluenza-3, Bovine viral diarrhea virus), bacteria (Mannheimia haemolytica, Pasteurella multocida, Mycoplasma bovis), and environmental stressors
