Learning outcomes

• To understand national and international NGOs and their functioning.
• NGO types and rules governing them.

Non-governmental organisations (NGOs), as the name suggests, are free from the government in its functioning. NGOs are groups or organisations of voluntary persons who do not represent any government action, and their members and associated persons manage all the functions. These numbers work as per the rules and regulations prescribed by the government, but they are independent of governmental control.

Learning outcomes

• understand the functioning of community radio in dissemination of from technology.

Introduction

Radio is the oldest type of media, and via radio the information revolution saw the green revolution. Farmers listen to the radio for weather, market price, and pestilence updates. Government began to encourage citizens by establishing radio rural forums (RRF). The primary purpose of a rural radio forum is to discuss and act. Here, a group of twenty individuals debate cultivation-related concerns and provide questions for the subsequent Radio rural forum. This allowed radio forum to get widespread popularity.

Learning Objectives

1. To raise awareness of a community problem and support its solution.
2. Induce the emotional participation of the community at the local level and establish a positive psychological climate for new activities.

The various methods of data gathering involve the use of appropriate recording forms. These are called tools or instruments of data collection; they consist of an observation schedule or interview guide, an interview schedule, a questionnaire, etc.

Objective: To write a script for a short video production.

Overview: A script is a written document that contains description of the setting, characters, dialogue, and stage directions for an audio-visual production. It is used to communicate information about actors, costumes, sets, and other aspects of production to those who will be involved in program production. While screenplay tells a story, a script (especially shooting script) mainly helps in production. Another difference between a screenplay and a script is that the former conveys what the audience will see on the screen, whereas the script guides the production team. A storyboard refers to pictorial representation of shots in a sequential order. It is very handy during shooting short videos like commercial or public service messages.

Objective: To write an article for a farm publication.

Description: Print media can be used at the receivers’ convenience and can be preserved for future reference. It can also be used to reach the readers at a relatively low cost and the information can be verified by the reader. Due to these advantages, print media is an important form of communication, especially for development purpose. The term “farm publication” is used to refer to any publication that is prepared by an extension agency/ development department and contains information related to improvement of farming practices. Farm publications can be of various types such as leaflet, folder, magazine, newsletter, etc. Farm publications are very useful for literate farmers and can also be used by illiterate farmers with the help of others.

The toaster is a kind of equipment used to toast bread in order to make it crisp. It has two slots which can hold two or four slices of bread. The electrical element produces the heat needed to make the bread hot and crisp. The toaster is a little apparatus intended to toast numerous sorts of bread items. Created in Scotland in 1893 and persistently created from that point forward, the most well-known family unit toasting machines are presently the pop-up toaster and the toaster broiler. Pop-up toasters make toast from bread in 1 to 3 minutes by utilizing warmth components.

Introduction
 
In India, most of the agricultural soils are deficient in one or more of the essential plant nutrients required for raising healthy crops and harvesting potential yield. Acidity, alkalinity, salinity, anthropogenic processes, nature of farming, and erosion are the main factors that can lead to soil degradation either alone or in combination of more than one factors.

Immunity is defined as the resistance to infection. This is carried out by the process of identification and removal of non-self material. In contrast to this, our body has to maintain immune tolerance to our own cells and tissues and develop the ability to distinguish these self-antigensfrom non-self (foreign) antigens. Tolerance means unresponsiveness of the immune system to an antigen. Immune tolerance is the process by which the immune system does not destroy an antigen. Tolerance can be either natural or induced.

Tomato is one of the most popular and widely grown nutritious vegetable in the world. Tomato (Lycopersicum esculentum Linnacus Karst.) belonging to the family Solanaceae is one of the most nutritious and remunerative vegetable crop. It is the world’s important vegetable next to potato. The crop is cultivated throughout the year. In Northern plains, the crop is cultivated during autumn, spring and summer. In South India, the crop is grown in June – July, October – November and January – February. The optimum season for seed production in southern India is October – December. Nursery raised in late October and transplanted in the first week of December will produce a good seed crop.

14.1. Introduction

Tomato is grown in India in abundance both in summer and winters. Tomato though botanically a fruit is generally considered as vegetable because of the way in which it is consumed. Fresh tomatoes are very refreshing and appetizing but can not be stored for a long period. During peak season, about 25% of the produce is spoiled due to mishandling and such losses can be avoided by converting tomatoes into different value added products. Tomato can be processed into pulp, paste, puree, juice, ketchup and sauce. In India, tomato sauce and ketchup are very popular. High quality products can be prepared from tomatoes by:

1. Using uniformly ripened, red coloured tomatoes.

2. Avoid prolonged heating and cool the product immediately after cooking.

3. Avoid using iron and copper equipments and utensils at any stage of processing.

A. Tomato and Tomato Products
Tomato though botanically a fruit is generally considered a vegetable because of how it is consumed. Commercial products from tomatoes include juice, puree, paste, ketchup, soup canned and dehydrated tomatoes. Processing of tomato is now practised from home scale level to large scale enterprise. As a semi-finished product, tomato puree is prepared on a small scale while at a large scale, tomato paste has gained commercial significance. Both puree and paste are used for the preparation of different finished products like ketchup, juice, soup etc. The method for preparation of these products is well standardized, however, some modifications concerning recipes are made in the processing plants owing to variations in the quality of the raw material. The methods for the preparation of different tomato products are discussed as under: -
I. Tomato Juice/Pulp
Tomato juice is an unconcentrated product consisting of a liquid with a substantial portion of the pulp, expressed from ripe tomatoes with or without the application of heat and the addition of salt. Tomato pulp/juice is the basic ingredient for the preparation of different tomato-based products such as tomato puree, paste, ketchup etc. Fully ripe tomatoes are used for the preparation of tomato juice/pulp. All green, blemished and overripe fruits should be rejected as they adversely affect the quality of the product. The juice obtained from overripe tomatoes is usually thin and unpleasant. The juice should be deep red in colour with a characteristic taste and flavour. The juice shall have about 0.4% acidity expressed as citric acid. Cane sugar (1%) is added to further improve the taste and flavour of the finished product.

Ingredient of tomato chutney: Tomato 1kg, sugar 500g, salt 25g, onion chopped 100g, ginger chopped 10g, garlic chopped 5g, red chilli powder 10g, cinnamon, cardamom large, aniseed, cumin, black pepper powder 10g each, vinegar 100ml and sodium benzoate 0.50g/kg final product.

1. Damping off
Diagnostic Symptoms
• Disease occurs in two stages, i.e. the pre-emergence and the postemergence phase.
• In the pre-emergence phase, the seedlings are killed just before they reach the soil surface.
• The young radical and the plumule are killed and there is complete rotting of the seedlings.
• The post-emergence phase is characterized by the infection of the young, juvenile tissues of the collar at the ground level.
• The infected tissues become soft and water soaked. The seedlings topple over or collapse (Fig.1)
Etiology
• Pathogen; Pythium aphanidermatum.
• The fungus has a characteristic mycelium, which coenocytic, hyaline, freely branching and thick hyphae.
• It reproduces both asexually and sexually.

Essentials for Quality Product Preparation

Plant ripened red tomatoes should be selected. Yellow and green fruits on processing yield dull colour and turn brown due to oxidation.

Never use iron equipment for processing. Lycopene oxidizes and turns brown when comes in contact with iron. It also forms black compounds with the tannins present in tomatoes or the spices which are used for product preparation.

Avoid prolonged heating and cool immediately to avoid over-cooking.

Sauce/Ketchup:-Fully ripe red fruits are selected, all green and blemish part are discarded. It is made from strained tomato juice or pulp and spices, salt, sugar and vinegar with or without onion and garlic and contains not less than 12% tomato solid and 25% total solid.

Ingredient of tomato sauce/ketchup: Tomato pulp 1kg, sugar 75g, salt 10g, onion chopped 50g, ginger chopped 10g, garlic chopped 5g, red chilli powder 5g, cinnamon, cardamom large, aniseed, cumin, black pepper powder 10g each, clove headless 5 number, vinegar 25ml or glacial acetic acid 5ml and sodium benzoate 0.25g/kg final product.

This is a medium sized moth yellowish brown in colour with a wing

span of about 3 cm and a body length up to 1.4 cm. There is a dark speck and a dark area on the outer margin of each forewing. The forewings also have greyish wavy lines and black spots of different sizes on the upper side.

Tomato is relatively recent addition to the world’s vegetable crops. Now became one of the most important vegetable crops and is popular & widely consumed. It is being grown extensively in USA, China, India, France, Israel and Netherland.
 
It is used in fresh and processed form. Among the vegetables maximum attempts have been made to improve this crop because of its short duration, easy cultivation and large number of seeds per fruit and this has made it an ideal crop for many research works. An exclusive Tomato Genetics Co-operative located in University of California, USA, published genetic information on the crop and maintains a large number of     collections which have already been thoroughly catalogued.
 
Origin and Distribution: Native of Peru in South America and spread to North America by migrating birds. Largest number of wild tomato forms is present in Mexico. Spanish Priests introduced it to Europe in around 1550. In Europe it is known as Poma amoris = Amorous apple (Love apple). Wild relatives found in narrow elongated mountainous regions of Andes in Peru, Ecuador and Bolivia and Galapagos islands. Domestication and cultivation of tomato appears to have first occurred outside its centre or origin. Domestication of tomato was first done by Mexican people i.e. Red Indians, which is considered as secondary center of origin. Now cultivated tomato is common in Peru but recently added to their diet.

Tomato (Lycopersicum esculentum Miller, 2n = 2x = 24, also known as Solanum lycopersicum, Family Solanaceae) has been the leading vegetable crop globally. Tomato genome is composed of approximately 950 Mb of DNA, more than 75% of which is heterochromatin and largely devoid of genes. The global production of tomato in 2017 has been 182 million tons from 5 million ha area giving a productivity of 36.4 tons/ha. Top 10 countries in tomato production in descending order are China, India, Turkey, USA, Egypt, Iran, Italy, Spain, Mexico and Brazil. Tomato is planted almost throughout the year in different parts of India in an area of 8 lakh ha (0. 8 million ha) with production of 20.8 million tons giving a productivity of 26 ton/ha. Tomato area in India is almost 10% of total vegetable area. The states accounting for major tomato production in India are Andhra Pradesh, Orissa, Telangana, Madhya Pradesh, Karnataka, Maharashtra, West Bengal, Chhattisgarh, Bihar, Gujarat, and Himachal Pradesh.

Out of total area, about 78% is planted with F₁ hybrid seed while remaining 22% of the area still goes to open-pollinated varieties. The average productivity of tomato close to 26 tons/ha is still very low compared with the global productivity of 36.4 tons/ha. However, with the introduction of high performing and disease resistant hybrids, the productivity and production are continuously improving. Most of hybrid tomato seed (95 tons) is sold by the private seed companies. There are more than 375 tomato hybrids in the commercial chain in India produced and marketed by different companies. About 50 hybrids out of these 375 hybrids are being grown on more than 80% of the area under tomato in India. Leading companies in tomato hybrid seed segment are Seminis (Bayer), Syngenta, Rasi HyVeg, and Namdhari (NHB, 2015; Kapur, 2016).

Tomato (Solanum lycopersicum L.) is one of the most commercially important vegetable crops globally, with a significant demand for high-yielding hybrids and improved open-pollinated varieties. Efficient seed production methodologies play a crucial role in ensuring the availability of genetically pure and high-quality seeds for commercial cultivation. Traditional hand emasculation and pollination remain widely used despite being labor intensive, given their economic feasibility due to high seed yield per fruit. Hybrid seed production is further refined through mechanized pollen collection and controlled pollination techniques, enhancing efficiency. Seed quality management, including rigorous isolation protocols, field inspections, and breeder and foundation seed production standards, ensures genetic purity and viability. Advances in molecular breeding and the application of marker-assisted selection (MAS) have enhanced the efficiency of parental line development and hybrid seed production. This chapter provides an in-depth review of tomato seed production methodologies, covering botanical characteristics, genetic resources, and breeding objectives aimed at improving disease resistance, abiotic stress tolerance, and fruit quality traits. It further discusses varietal advancements in the public and private sectors, highlighting elite hybrids and open-pollinated cultivars tailored for different agro-climatic conditions. Additionally, the package of practices for seed production in tomato underscores the importance of isolation, field inspections, seed extraction methods, processing techniques, and quality assurance standards to maintain genetic purity and seed viability.

Origin, domestication and adaptation in India
Tomato was classified under Lycopersicon for several years although, initially Linnaeus (1753) classified it in the genus Solanum. Recently, molecular studies provided new data on the relationships of tomato-potato and based on these results, tomato has been again assigned to the genus Solanum. Solanum section Lycopersicon includes the cultivated tomato (Solanum lycopersicum) and its wild relatives, Solanum lycopersicum being the only domesticated species. The wild cherry tomato, Solanum lycopersicum var cerasiforme, the ancestor of the modern cultivated tomato has been originated in Peru-Ecuador-Bolivia region of the Andes. The Veracruz-Puebla region of Mexico is the centre of domestication of the cultivated tomato. From Mexico, tomato was taken to Italy, Spain, Portugal and other European countries, Africa and Middle East by the explorers in the 16th century. It was taken to Philippines after its discovery by Magellan in 1521, and from there it was taken to other Asian countries. Tomatoes did not have an easy passage even in Europe. The fruit got tagged as the “poison apple” in Britain, France, Spain and other European countries. Tomato moved to the USA from northern Europe around 1781 where it was first grown by Thomas Jefferson in Virginia.

At the back of the mouth on each side there are two small lymphoid organs known as tonsils. Normally they are about the size of a Lima bean, but they can become very larger if severely infected. The lingual tonsil is located at the back of the tongue close to other tonsils. There are two more lymphoid masses of tissue behind the soft palate known as adenoids. They make protective ring at the back of the nose & throat to keep infection from spreading throughout the body. Most of the germs enter through the mouth, nose and throat.

After becoming an adult the adenoids have largely disappeared. In childhood both the tonsils and adenoids may become very large. It makes swallowing painful and breathing difficult. In childhood large tonsils are common. The main reason of infection is due to certain types of streptococcus germs. Mouth breathing, nasal speech, a chronic cough are caused by the enlarged adenoids. The patient may also have halitosis or bad breath.

Introduction

The nursery is an area where tender seedlings are raised and conditioned before planting out in transplant beds or directly in the field. The increasing demand for quality planting material has up stepped the nursery business in many countries. The sophisticated technology, research and novel production approaches has transformed the traditional horticultural nursery to a technology intensive business. The tools and accessories associated with nursery production helps in aiding productivity of the nursery. The colour-coded and labelled plant materials, textured pots etc. are fascinating to consumers, indirectly increasing the salability of the plants and profitability of the enterprise. 

Introduction

Challenges in agriculture and natural resource management in the past have prompted changes in agricultural education, research, and extension globally. The sustainable development of agriculture in a country largely depends on the effectiveness of its agricultural extension strategies, encompassing approaches, service delivery, methodology, and processes. The desired outcome of agricultural development is farmers’ outcomes, achievable through engagement, learning, and participation in research and extension processes. Agricultural extension played a significant role in the green revolution by providing farming communities with appropriate technologies and optimal cropping practices. This helped countries transition from being food deficit to food exporting (Ratnakar, 2016). Additionally, extension services play a crucial role in expanding knowledge, skills, and attitudes about the management of socio-economic-agricultural practices by understanding the existing techno political ecosystem and exploring a basket of technology alternatives for making informed decisions.

The major tuber crops cultivated in tropical countries are: cassava (Manihot esculenta Crantz), sweet potato (Ipomoea batatas L.), yams (Dioscorea sp.), aroids (Amorphophallus, Alocasia, Xanthosoma, Colocasia ), Canna edulis, arrowroot, Chinese potato, winged bean and yam bean. In addition to this, there are a number of under exploited and under utilized tuber crops grown as wild cultivars having medicinal and pharmaceutical applications. Processing and utilization of tuber crops as food are traditional with both primitive as well as modern equipments being in use (Nanda and Kurup, 1994). One of the oldest traditional processing tools is a stone pounder for making poi from taro in Hawaii.

For maintenance of garden, a person should well acquainted with different types of tools and implements and their uses. A tool and implement is any physical item that can be used to achieve a goal, describe a procedure or process with a specific purpose. Tools that are used in particular fields or activities may have different designations such as instrument, utensil, implement, machine or apparatus. The set of tools needed to achieve a goal is called equipment. The knowledge of constructing, obtaining and using tools is technology. Varieties of implements and tools are required for carrying out the various garden operations like digging, breaking soil, clods, removal of weeds, levelling of ground, mowing lawns, planting of bulbs, layering and grafting, manuring etc. Some of the gardening hand tools are spades, garden forks, pitchfork, hoes, ploughs, shovels, pruners and ice choppers. Many hand tools have been replaced by electronic tools but gardening and landscaping hand tools are still preferred, because they are easier to use and cheaper. Garden tools can be made up of wood, metal or plastics. Landscaping and Gardening is one of the most rewarding and stress-relieving hobbies. The most common garden tool set includes: shovels, rakes, spades, diggers, trowels, etc. Gardening tools can be power or hand driven. There are some garden tools commonly used (Table 1).

Sickle: Used for cutting grass, fodder and harvesting crop. Sickle made of steel is better and lasts longer.

In dryland areas, moisture conservation accounts prime most important concept for maximizing productivity of dryland crops. Varied topographic and agro- climatic conditions ranging from arid to semi-arid climates with high evaporation because of varied temperature regimes permit the cultivation of drought resistance crops. Reducing the cost of cultivation without compromising the socio-economic status of farmers is prime importance. Conservation of moisture by reducing the weed menace is great task performed by the dryland farmers. Under such situations, effective utilization of dryland tools and implements used are of a primitive nature throughout the dryland farmers for higher factor productivity. Traditional farm tools and implements for self-sustenance have been adapted through experience over generations to meet emerging socio- economic and farming challenges.

Relatively small yields consequently larger areas must be farmed for a given return and the successful exploration of dryfarming requires the adoption of methods. The methods which enable farmers to do the maximum effective work with the smallest expenditure of energy. The type of soils and topographic conditions largely influence the type, size and shape of particular tillage tools/ implements among the dryland farmers. The following is a list of local tools/ implements found in the various dryland regions.

Introduction

The capabilities and effort to collect the geographic data has increased dramatically in the last decade to cope up with the increasing demand for the support of decision making and planning process in the state, national and global level.  From the Government sector, there is a need for spatial data to make quick responses to natural disasters, industrial accidents and environmental crises as actions will be decided based on geography. There is constant pressure to make wise decisions in a more time and cost effective and efficient manner. Accurate and current geospatial data are critical to these decisions.

Scientific research is always based on observable and measurable facts. This applies to physical as well as humanitarian fields of science. In order to investigate social or psychological phenomenon, most of the times we need quantified information related to the phenomenon under investigation. In order to secure this data, we need one or more method/ means of collecting observable/measurable data.

Introduction

The Web-enabled infrastructures, practices and strategies are creating confusions disruptions for virtually every institution and enterprise. The responses to these disruptions are progressively leading to new practices, business models, and strategies in a variety of domains posing challenges to the profession of librarianship. The acquisition, assimilation, and sharing of knowledge is one such sphere that is really experiencing a revolution.

Data analysis plays a pivotal role in social science research, transforming raw
data into meaningful insights. In this study, data collected from the field were meticulously scored, tabulated and analyzed using a variety of statistical tools to meet the specific objectives of the research. These tools not only help in summarizing and interpreting the data but also aid in drawing valid and reliable conclusions. Statistics is the science of assembling, organizing and analyzing numerical data. The following statistical techniques and tools were employed:
Descriptive Statistical Tools
1. Frequency Distribution
Definition: Frequency refers to the number of times a particular value or category occurs in a dataset.

Gender analysis is the first and the foremost critical step towards gender responsive planning and programming. It involves collection and analysis of sex disaggregated information. It examines the differences, commonalties and interactions between women and men. Gender analysis examines women’s and men’s specific activities, conditions, needs, access to and control over resources, access to development benefits and decision-making.

Gender analysis helps to clarify the specific and often different capacities, vulnerabilities, needs and coping strategies of men and women, and indicates where opportunities for targeting effective strategies lie. Established patterns of gender inequality and inequity can be explored, exposed and addressed. This may provide opportunities and entry points to develop programs that support efforts to build more equitable gender relations. It aims to achieve positive change for women.

Elements of Gender Analysis

a) Natural: Land, water, forests, rivers etc.

b) Economic: Work opportunities, wages and remuneration, remittance, credit and production inputs.

c) Social: Formal and informal education and social services- religion and cultural norms like dress, defining private and public spaces.

While structural genomics aims to describe the protein structures coded by the genes present in the genome, functional genomics deciphers meaning of the coded information at transcriptome, proteome and interactome level. In the previous chapter we have seen how a gene can be identified by creation of mutants, genetic and physical mapping, and by sequencing the gene. Another source of possible gene structures come from genome sequence information, which by using computational algorithms identifies a number of ORFs that have the structural configuration of a gene. A third option of identifying a gene is identification of differences between wild type and mutant at RNA level, by analyzing the transcriptome. If we are able to identify differences in RNA expression pattern between these two, the information can be used to search back the gene sequences responsible for the differences. From proteome analysis inferences on expression of proteins and their interaction in the functional network of the cell with other proteins, DNA, RNA and cellular 

The primary target of genomics is identification and characterization of genes and gene products. Starting point of genomics may be a whole genome sequence, from which gene and protein structures can be predicted by computational and bioinformatics approaches (in silico genomics), or genes can be identified step by step starting from identification of a phenotype by induction and detection of mutation, construction of a genetic map demarkating the position of the character, physical location, identification of the gene, cloning and characterization of the gene or genome sequence by sequencing followed by expression analysis to correlate the phenotypic expression (in vivo genomics). Alternatively, genes can be identified by developing knockout mutants by random or site directed disruption of a reading frame and then determining the protein product as well as phenotypic expression.

This chapter would typically focus on the practical implementation aspects of a national drought management policy, emphasizing the scientific and technological tools, analytical models, and ongoing research necessary for effective drought preparedness, mitigation, and response. 10.1.1 Drought Monitoring and Early Warning Systems • Indicators and Thresholds: Defining and utilizing a suite of meteorological, agricultural, and hydrological indicators (e.g., Standardized Precipitation Index (SPI), Aridity Anomaly Index (AAI), Normalized Difference Vegetation Index (NDVI), soil moisture data, reservoir levels, groundwater levels). • Monitoring Networks: Establishing and maintaining networks of ground-based weather stations, rain gauges, and river flow gauges. • Remote Sensing and GIS: Utilizing satellite imagery and Geographic Information Systems (GIS) for large-scale, near real-time drought assessment, vegetation health monitoring

A broader definition of a tool is an entity used to interface between two or more domains that facilitates more effective action of one domain upon the other. The most basic tools are simple machines. For example, a crowbar simply functions as a lever. The further out from the pivot point, the more force is transmitted along the lever. A hammer typically interfaces between the operator’s hand and the nail the operator wishes to strike.
A telephone is a communication tool that interfaces between two people engaged in conversation at one level. And between each user and the communication network at another. It is in the domain of media and communications technology that a counterintuitive aspect of our relationships with our tools first began to gain popular recognition.
Marshall McLuhan famously said “We shape our tools. And then our tools shape us.” McLuhan was referring to the fact that our social practices co-evolve with our use of new tools and the refinements we make to existing tools.

6.1 Introduction

Torrefaction is a thermophilic process of biomass conversion into a solid, friable, homogenous coal-like material, which has better fuel characteristics than the original biomass. Torrefaction involves the heating of biomass material in the absence of air at 250 to 300°C temperature. Torrefaction produces high-grade hydrophobic nature solid biofuels from various streams of woody biomass or agro residues.Torrefied biomass has high energy density then the original biomass which make torrefied biomass as renewable alternate source for power generation in coal power plant. Torrefied biomass being hydrophobic in nature can be stored easily for longer duration with negligible biological degradation. At 250-300°C temperature volatilization has been taking place and around 30% mass of the biomass is reduced as compared to original untorrefied biomass with net energy loss of approximately around 10%.The end product is a predictable, homogeneous, hydrophobic, high value solid biofuel with far higher energy density and calorific value than the original biomass feedstock. During the torrefaction process a combustible gas is released, which can also utilised to provide heat to the process. The process diagram of torrefaction process is shown in Fig. 6.1.

Torsion, or twisting, of one or more segments of the alimentary canal is a serious and often life-threatening condition in animals. It involves the abnormal rotation of the gastrointestinal tract along its axis, resulting in obstruction, vascular compromise, and subsequent tissue death. Torsion can affect differentparts of the alimentary canal, including the stomach, intestines, and cecum, and  is more commonly observed in certain species and breeds due to anatomical and environmental factors.
This condition requires prompt diagnosis and treatment to minimize morbidity and mortality. This discussion provides a comprehensive understanding of torsion, its pathophysiology, causes, clinical signs, diagnostic methods, and management strategies.
Pathophysiology of torsion
The alimentary canal is suspended in the abdominal cavity by mesenteric attachments that contain blood vessels, nerves, and lymphatics. When a segment of the canal twists along its mesenteric axis:
1. Mechanical obstruction: The lumen becomes occluded, preventing the passage of ingesta or gas.

The torsion or displacement of the rumen, reticulum, omasum, and abomasum are significant conditions affecting ruminants, particularly dairy cattle. These gastrointestinal disorders result in severe digestive disruptions, metabolic imbalances, and, if untreated, life-threatening complications. This chapter delves into the causes, clinical manifestations, diagnostic approaches, and management strategies for these conditions, focusing on each stomach compartment of ruminants.
Anatomy and function of rumen, reticulum, omasum, and abomasum Ruminants have a complex stomach with four compartments:
1. Rumen: The largest compartment responsible for microbial fermentation and digestion of fibrous feed.
2. Reticulum: Works closely with the rumen in fermentation and acts as a sorting chamber.
3. Omasum: Absorbs water, electrolytes, and VFAs while filtering digesta.
4. Abomasum: Functions as the true stomach, secreting acid and enzymes for protein digestion.
Torsion or displacement in any of these compartments disrupts their normal functioning, leading to severe health issues.
Displacement or torsion of the rumen
Rumen displacement or torsion is less common than issues in the abomasum but can still occur under specific circumstances.

Definition
The residue of incineration at 550-600ºC is the crude ash.

Reagent
Dilute hydrochloric acid -approximately 5 N prepared from concentrated hydrochloric acid. Dissolve 445 ml conc. hydrochloric acid (about 36 percent HCl) in one litre distilled water. 

Procedure for Total Ash Estimation
Take a vitreosil crucible in oven at 100ºC for six hours, remove and keep it in a desiccator and weigh up to constant weight. About 5-10 g of sample is taken in the weighted vitreosil crucible. The material in the crucible is charred on a low flame and the crucible is then kept in muffle furnace and temperature is allowed to raise to 600ºC and kept constant for two hours. It is removed on cooling and kept in a desiccator  and weight of crucible is taken.
