PAPER - I
SECTION A

1. Write short notes on any three of the following in about 200 words each:
(a) Factors affecting nutrients consumption by large ruminants
(b) Trace elements requirements of poultry for-egg
(c) Recommendations for improving feed resources in India
(d) Role of water-soluble vitamins in animal health

2. Mineral mixtures are routinely used as supplement to feeding rations. What do they contain and in what way do these components help the animal?

3. (a) In feeding pigs, state the primary differences as compared to feeding of ruminants that need to be observed.
(b) Name and discuss at least five important steps required to balance a ration.

4. (a) Compare the different system of farming.
Which one would you recommend to a marginal farmer and why?

(b) How are the water needs of large ruminants met under natural conditions? What role does water play in the animal body?

SECTION B

5. Write short notes on any three of the following in about 200 words each:

(a) Digestion and absorption of carbohydrates in the alimentary tract of non-ruminants

(b) Collection and transport of raw milk from rural areas

(c) Factors affecting post-natal growth in a maturing calf

(d) Interdependence of agriculture and livestock farming

6. (a) What are the good qualities of a semen dilutor? Can a single semen dilutor be used for diluting semen of various species of animals if not, why?
(b) What are the main advantages and disadvantages of using frozen semen for artificial insemination?

7. 'Success in sheep business is largely measured by percentage of lamb crop raised and kilograms of lambs marketed per year." How would you achieve this by using modern management techniques if you are a sheed breeder?
