  11. Grass staggers and Blind Staggers.
  12. Net protein utilization and net protein value.
  13. Flushing and steaming-up.
  14. What are the common sources of calcium and phosphorus? How high intake of calcium affects the utilization of other minerals? Explain, how ‘Nutritional Secondary Hyperparathyroidism’ develops in animals?
  15. What points will you consider while formulating a ration for a dairy buffalo? A farmer gives 20 kg green maize (25% DM, 1.2% DCP and 16% TDN), 5 kg wheat straw (90% DM, 0% DCP and 40% TDN) and 4 kg concentrate mixture (90% DM, 14% DCP and 68% TDN) daily to a lactating buffalo weighing 450 kg and yielding 10  kg milk with 7% fat during her first lactation. The maintenance requirements in 280 kg DCP and 3.4 kg TDN, whereas the requirement for 1 kg milk production in 63 g DCP and 460 g TDN. Indicate the deficiency or excess of nutrients in terms of DCP and TDN.
  16. How will you develop a practical and economic ration for commercial broiler production?


  1. Many non-nutritive substances are often being mixed in animal and poultry ration as growth-promoters. Discuss the uses and abuses of these growth-promoters.
  2. Why are broilers and layers fed different types of rations? What are the similarities and dissimilarities in these two rations?
  3. How will you design an economic ration of pigs for production of lean meat? Explain.
  4. What is silage? Discuss in brief about the anti-nutritional factors commonly found in animal feeds.
  5. Discuss at least two methods that are utilized in formulating animal rations.
