The nutritional value and overall effectiveness of fish feed are heavily influenced by the selection and proportion of ingredients and additives included in its formulation. Ingredients provide the fundamental nutrients—proteins, carbohydrates, fats, vitamins, and minerals—while additives are used to improve digestion, flavor, immune support, and feed stability. A sound knowledge of these components is essential for developing economical and nutritionally balanced feeds tailored to different fish species and farming systems. Proteins are the primary building blocks in fish feed, necessary for muscle development, enzymatic functions, and growth. Fishmeal has long been regarded as the most effective protein source due to its excellent amino acid composition and digestibility. However, concerns around cost and sustainability have encouraged the use of plant-based alternatives such as soybean meal, groundnut cake, mustard oil cake, cottonseed meal, and insect-derived

Lameness in dairy animals is a serious health problem all over the world causing substantial economic losses to dairy industry owing to reduced milk production, reduced reproductive performance, cost of treatment including medicines, increased risk of culling, death, and the development of other diseases. Lameness can be defined as a state of being unable to walk properly because of pain in the limbs or foot. The incidence of lameness in the dairy herd is variable (1 to 50%) depending on the farm. In USA its incidence varies from 13 to 55% (Hoffman et al., 2014; Cook et al., 2016). Lameness may be due to diseases of limb and/or hoof of infectious and/or noninfectious origin. Lameness usually affects hind limbs because of greater load of the body on hind limbs. A lame animal adjusts gait and posture depending on the origin of the pain (foot or upper limb). Clinical signs of lameness include changes in locomotion (e.g. decreased speed, decreased stride, length and tracking, increased abduction,

South Asia, which includes countries like Bangladesh, India, Nepal, and Pakistan, has a predominant focus on rice production. Rice is not only a staple food but also a critical part of the cultural and economic fabric of these nations. The climatic conditions and extensive river systems in this region provide ideal conditions for rice cultivation. For instance, in Bangladesh, rice accounts for nearly 70% of caloric intake and employs a significant portion of the rural labor force (FAO, 2023). In India, rice is grown across 44 million hectares, particularly in the eastern and southern belts (Ministry of Agriculture & Farmers Welfare, India, 2022). Nepal relies heavily on monsoon-fed paddy farming, while Pakistan is a major exporter of basmati rice (Pakistan Bureau of Statistics, 2022). Diversification in Southeast Asia Southeast Asian countries such as Thailand, Vietnam, Indonesia, Malaysia, Myanmar, Philippines, and Lao PDR are gradually diversifying their agricultural production. While rice remains

This chapter examines the major forms and mechanisms of immunity. It distinguishes innate immunity from adaptive immunity and explains specificity, diversity, immunological memory and self–non-self recognition. Natural and artificial forms of active and passive immunity are discussed through examples involving infection, vaccination, maternal antibodies and antiserum administration. The chapter introduces pattern-recognition receptors, pathogen-associated molecular patterns and Toll-like receptors involved in microbial recognition. It also covers inflammation, its cardinal signs, acute-phase proteins and the roles of neutrophils and other innate defence components. These objective questions provide a clear foundation for understanding how animals resist infections and develop long-lasting protective immune responses.

This chapter explains how B-cell receptors, T-cell receptors and major histocompatibility complex molecules participate in antigen recognition. It differentiates MHC class I and class II pathways and describes the processing of endogenous and exogenous antigens. The roles of dendritic cells, macrophages and B lymphocytes as professional antigen-presenting cells are examined. Topics include MHC restriction, antigenic peptides, proteasomal degradation, ubiquitination and recognition by CD4-positive and CD8-positive T lymphocytes. The chapter also discusses superantigens, opsonization, phagocytosis, T-independent antigens and species-specific MHC systems such as BoLA and the avian B complex. These concepts explain the initiation of adaptive immune responses.

The Acceptance Quality Limit, commonly called AQL, is a statistical sampling system used to determine whether a production lot satisfies a predetermined level of quality. Inspectors examine a randomly selected sample and accept or reject the entire lot according to the number and seriousness of defects found. AQL does not require absolute freedom from defects; instead, it establishes an acceptable threshold based on the product, buyer expectations and defect criticality. It provides an efficient and objective alternative when complete inspection is impractical. Textile and apparel inspections commonly follow ISO 2859-1 or ANSI/ASQ Z1.4, which prescribe inspection levels, sample sizes and acceptance-rejection criteria.

This chapter introduces ergonomics as the science and practice of designing tools, systems and environments around human capabilities and limitations. It explains the meaning, significance and principal objectives of ergonomics, including safety, comfort, efficiency and human well-being. The historical development of the discipline is traced from early toolmaking and industrialization to contemporary human-centred design. Anthropometry is introduced as an essential basis for matching furniture, equipment and workplaces to different users. Examples from domestic life, education and professional settings demonstrate the practical relevance of ergonomic thinking. The chapter establishes human-centred design as the foundation for developing functional, safe and accessible solutions.

This chapter examines the human body as an integrated working system governed by anatomical, physiological and biomechanical principles. It describes the roles of the musculoskeletal, nervous, cardiovascular, respiratory and metabolic systems in movement, strength, coordination and endurance. Muscle strength, joint range of motion, posture, flexibility and physical work capacity are discussed in relation to workplace demands. The chapter distinguishes static and dynamic work and explains how unsuitable loads or repetitive tasks contribute to fatigue and injury. Individual differences associated with age, fitness, body dimensions and physical capability are also considered. These concepts provide a scientific foundation for setting safe workloads and designing tasks around natural human limitations.

This chapter investigates the ergonomic design of transportation systems, including cars, buses, bicycles and other modes of mobility. It explains how seating, posture, visibility, controls, displays, vibration and environmental conditions shape the physical and cognitive experience of travel. Vehicle components should accommodate a wide range of body dimensions while maintaining neutral posture and convenient access to essential controls. Adjustable seating, lumbar support, suitable padding and appropriate joint angles are discussed as measures for reducing fatigue and spinal loading. The chapter also examines sensory feedback, information presentation and mobility-related technologies. Its central argument is that human-centred transportation design makes journeys safer, more comfortable, intuitive and accessible.

Lameness is an important health and production problem in dairy animals because it affects mobility, feeding behaviour, milk production, reproduction and welfare. This chapter focuses on practical evaluation of lameness and identification of the affected limb and underlying lesion. Examination includes observation during standing and walking, assessment of weight bearing, limb manipulation and examination of the foot. Washing the foot, inspecting the interdigital area, coronary band and heel, and using hoof testers can help localize pain. Recognition of abnormal gait and foot lesions enables early intervention and management. Effective lameness assessment is therefore an essential component of dairy herd health.

As mentioned above Bougainvillea is one of the most widely grown important perennial ornamental shrubs with numerous attractive plant colour (leaf) and shape, and bract colours and shape. It is very popular for its multipurpose use. Inspite of beautiful bract colour it can not be enjoyed as cut flower as its shelf-life is very limited. Bracts start drooping within few minutes after cut from the main plant. Dehydration techniques have been developed at CSIR-N.B.R.I., Lucknow, by which flowers and foliage retain their fresh look for several months or even years after dehydration. Their original shapes, colour and size remain as they were before dehydration and, thus, making them highly suitable raw materials for interior decoration and may be enjoyed for a long time and can be used for any occasion. NBRI has standardized two methods viz. Press Drying and Embedding (drying through embedding in sand and silica gel and drying using hot air oven, microwave oven and solar cooker). Bougainvillea leaves and bracts can be dehydrated beautifully by both the methods and the dried products are utilized for preparation of different types of commercial decorative items. 

Bhuva is a small village in north-west Gujarat – India.  My mother was born there. The loving people of Bhuva called me ‘Bhano’ (Sister’s Son / Nephew) and it was my favourite place to go as a child. I have my fondest memories of Bhuva, but could not visit for several decades, until when I was once at the Junagadh Campus of Gujarat Agricultural University, to inaugurate the International Conference on New Developments in Agriculture. Bhuva was not too far and I decided to go there. Soon as I reached, a familiar face, now aged with time, recognized me from a distance and with tears rolling from his old eyes (and mine) he hugged me, calling out “MaroBhano, MaroBhano” (My sister’s son, my sister’s son)! Now in his eighties, it was overwhelming to meet Nanji Ata, who I always remembered being wise, educated and cheerful. He was a relatively progressive farmer with about 6 to 7 acres of land, a few cows and a buffalo. Though water was scarce and saline, he managed to make a good living and was considered a well to do man.

Chemical changes occur during oven-drying because of the direct effect of high temperature, or of enzymic or bacterial changes during the early stages of drying, or of loss of volatile consitituents. Feeds containing molasses should be ground in a mortar.

Dried materials should be ground to pass 1 mm sieve. Samples expected to moisture during the treatments are usually predried. If wet samples are used directly in the assay, sufficient large quantity has to weighted out. In the first stage, roughages about 250-1000g are used, somewhat dependent upon homogeneity and moisture content of the wet material. These samples are weighted into trays and dried in draft oven at 60-70ºC. The dry samples are then again weighed, determined the moisture content. The trays are then left to equilibrate in air at room temperature for two days. before a second reweighing of the trays with samples. Then the sample is milled and filled into airtight containers and labelled as dry samples.

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.

Introduction

Wet ashing is suitable for the determination of Ca, Cu, Fe, Mg, Mn, K, Na, Se and Zn in biological samples and may be applicable to the determination of other elements as well.

The organic matter of the sample is oxidized with concentrated nitric acid and perchloric acids. The acids are partially removed by volatilization and the solube mineral constituents remain dissolved in nitric acid. Any silica present is dehydrated and made insoluble.

Estimation of Cellulose in Feeds and Fodders
Principle

The feed well ground is digested with acetic acid which dissolves all other constituents like protein, disaccharides, fatty acids, etc., and cellulose and mineral contents are unaffected. The residue is made acid and alcohol free by washings. Alcohol removes water, benzene removes pigments and fat and at the end the sample is dried and ashed. The difference between the dried weight before ashing and weight after ashing gives cellulose content of the feed sample.

Method I
Reagents
    1.    20% sodium carbonate.
    2.    Conc. hydrochloric acid.
    3.    4% sodium hydroxide
    4.    10% calcium chloride
    5.    Ammonium hydroxide
    6.    Potassium permanganate (0.05 N)

Procedure
Take 2-5 g of powdered sample in a beaker without spout, and add 40 ml of water and boil for half an hour. In case of faeces, add 40 ml of 4 percent NaOH instead of 40 ml of water to form silicates. Now boil, for half an hour with cold water flask over the beaker, then add 10 ml of 20 percent sodium carbonate solution and boil for  another half an hour. During these two cooking processes, the following changes take place.

Principle

Cyanide is distilled from chloroform and water soultion into KOH solution, forming potassium cyanide. KCN is titrated with silver nitrate; 2 KCN + AgNO₃ = KCN. AgCN + KNO₃. An excess of AgNO₃ produces insoluble AgCN, which is the end point of titration.

Principle
(Method of Patterson 1963)

The albumin bound long-chain fatty acids of plasma are usually referred to as unesterified or non-esterified fatty acids (NEFA) to distinguish them from the long-chain fatty acids present in the esterified form in neutral fats and phospholipid. In the case of ruminant plasma, it is also important to distinguish these “free fatty acids” from the small molecular weight steam volatile fatty acids of dietary origin which are found in the free state as the carboxylate ion.

Basically, the method of Dole (1959a) has been used to estimate plasma NEFA employed by Annison (1960), which is to evaporate the heptane extract of plasma to dryness before titration. This is conveniently done in a stream of nitrogen on a warm hot plate rather than by evaporation in vacua. In place of the 0.05 M- phosphate buffer (pH 6.0) of Annison or the 0.02 N-H₂SO₄ used by Dole (1956a), in the present method 0.02 N-HCI is used as an extraction medium. This is preferred because owing to its volatility, it is less likely to cause serious accidental contamination of the supernatant heptane layer.

(Method of Joseph Mac Gee, 1959)
Principle

A simple and rapid enzymatic method for the quantitative estimation of total cis-methylene- interrupted polyenoic acids has been devised. Linoleic, linolenic and arachidonic acids, the more common acids of this group were used to calibrate the method. The potassium salts of the fatty acids are oxidised by atmospheric oxygen in the presence of the enzyme lipo-oxidase, and the absorption of the conjugated diene hydroperoxide is measured at 234 mµ. As little as 5 µg of linoleic acid can be quantitatively measured with good accuracy and precision. The total content of polyunsaturated fatty acids containing the cismethylene-interrupted diene structure of fats, oils, hydrogenated oils, fatty acids, esters blood plasma, microorganisms and plant seeds has been measured directly by this method.

(Method of Bloor, 1928 Modified by Folch et al., 1957)
Gravimetric Method — Principle

Total lipids in plasma consist of neutral fats, phospholipids, chloesterol esters and free cholesterol. Minor components include non-esterified fatty acids (NEFA), phosphatides and sphingo myelin. Total lipids in serum or plasma are extracted using ethyl alcohol and petroleum  ether, separated and weighed after drying at 105ºC.

Procedure
Pipette 5 ml serum in a separating funnel, add 5 ml ethyl alcohol and 12.5 ml pertroleum ether. Shake the contents of funnel two times for 3 min. atleast. Keep the contents of funnel as such for one hour. Transfer the contents of funnel in the moisture cup, dry and weigh. Calculate the result by difference method using the following formula.

Introduction

(Titrimetric Method of  Cherry and crandall, 1932 Modified by Tietz and Fiereck, 1966).

In 1932, Cherry and Crandall employed olive oil as the substrate for pancreatic and serum lipase (LPS. Triacylglycerol lipase) determinations. In subsequent years this method was improved (Tietz et al., 1959; Tietz and Fereck, 1966: Tietz. 1972), reducing the original 24 h, period to 6 h and finally to 3 h.

Principle
This procedure is based on the hydrolysis of triglycerides in olive oil into fatty acids, diglycerides and to some small extent into monoglycerides and glycerol.

(Method of Cocimano and Leng, 1966; Conrad, 1972; Varady & Harmeyer, 1972)
Hypothesis

The validity of measuring urea kinetics using a single dose of ¹⁴C-urea and using urinary excretion as a sampling system is based on specific assumption:

    1.    There is a rapid equilibration of ¹⁴C-urea with the endogenous urea pool following infusion. This pool is conceived to be a measure of all body compartments permeable to urea and in equilibrium with the plasma urea pool. 

    2.    Experimental animals are metabolically maintained in a steady state during the test period and metabolic breakdown of urea is random.

    3.    Specific radioactivity for urinary urea is proportional to the dilution of replenishment and simultaneous depletion rate of the urea pool.

    4.    That the metabolic parameters of urea are correctly measured.

    2.    Agitator : or water bath with shaking device and having temperature controlling unit.
    3.    Glass fiber filter paper.

PEG Estimation
Introduction
Polyethylene glycol (PEG) is used as a marker for the estimation of rumen water volume and ruminant digestion studies (Hyden and Ekman, 1953). Long back, Hyden (1955) developed a turbidimetric method which is described below :

Principle
When trichloroacetic acid is added to a solution of PEG, a turbidity is produced, which can be measured photo-electrically. The intensity of the cloud, which consists of finely divided oily droplets, is increased in the presence of barium ions. Protein and sulphate must be completely removed from the sample before the addition of the trichloroacetic acid reagent. Sulphate is precipitated with barium chloride and the proteins are removed essentially according to Samogyi (1945). The method has been developed for determination of PEG in ruminal and abomasal fluids, but it has been tried with other biological materials too.

Enzymes are biocatalysts composed of amino acids. Enzyme reactions are highly specific. It binds to the substrate to form a reversible intermediate product called enzyme substrate complex. As the concentration of the substrate increases the rate of formation of the intermediate complex also increases. This increase in velocity of the reaction is in a hyperbolic manner till it achieves the maximum velocity called Vmax .At this point all the enzymes will be in the form of ES complex. Substrate concentration will be in at its optimum level i.e. further increase in substrate concentration will not affect the rate of the reaction. The substrate concentration at which the rate of the reaction is half the maximum velocity Vmax is called the Michaelis-Menten constant, Km. This is constant for the given enzyme acting on the same substrate.
