evaluation of feeding experiments, digestibility and balance studies. Feeding
standards and measures of food
energy. Nutrition requirements for growth, maintenance and
production. Balanced
rations.

maturation, growth curves, measures of growth, factors affecting growth,
conformation, body composition, meat quality.
2.2 Milk Production and Reproduction and Digestion : Current
status of hormonal control of mammary development, milk secretion and milk
ejection. Male and Female reproduction organ, their components and function.
Digestive organs and their functions.
2.3 Environmental Physiology : Physiological relations and their
regulation; mechanisms of adaptation, environmental factors and regulatory
mechanism involved in animal behaviour, methods of controlling climatic stress.
2.4 Semen quality : Preservation and Artificial
Insemination-Components of semen, composition of spermatozoe, chemical and
physical properties of ejaculated semen, factors affecting semen in vivo and
in vitro. Factors affecting semen production and quality preservation,
composition of diluents, sperm concentration, transport of diluted semen. Deep
Freezing techniques in cows, sheep and goats, swine and poultry. Detection of
oestrus and time of insemination for better conception.
3. Livestock Production and Management :

with advanced countries. Dairying under fixed farming and as a specialised
farming, economic dairy farming, Starting of a dairy farm. Capital and land
requirement, organisation of the dairy farm.
Procurement of goods; opportunities in dairy farming, factors
determining the efficiency of dairy animal, Herd recording, budgeting, cost of
milk production; pricing policy; Personnel Management. Developing Practical and
Economic ration for dairy cattle; upply
of greens throughout the year, field and fodder requirements of Dairy Farm,
Feeding regimes for day and young stock and bulls, heifers and breeding animals,
new trends in feeding young and adult stock; Feeding records.
3.2. Commercial meat, egg and wool production: Development of
practical and economic rations for sheep, goats, pigs, rabbits and poultry.
Supply of greens, fodder, feeding regimens for young and mature stock. New
trends in enhancing production and
management. Capital and land requirements and socio-economic
concept.
3.3. Feeding and management of animals under drought, flood and
other natural calamities.
