Principles of Animal Nutrition

Contents:

A brief history and scope of animal nutrition. Nutrients and their classification. Comparative digestive anatomy and physiology of ruminants and non-ruminants.  Pre-gastric and Post-gastric digestion and absorption of major nutrients. Rumen ecology. Regulation of feed intake in non-ruminants and ruminants. Classification and functions of nutrients. Importance of water in the animal bodies its sources, requirements and losses. Carbohydrates nutrition: Structure classification, digestion and metabolism. Volatile fatty acids (VFA): production, absorption and metabolism in ruminants. Lipids: classification, structure, digestion and metabolism. Protein and amino acid: classification, structure digestion and metabolism. Introduction to mineral and vitamins in animal nutrition.

Practical

Classification and identification of feedstuffs, their nutritional composition. Sampling techniques for feed ingredients and forages. Sample preservation, Processing of samples for chemical analyses. Proximate analysis: dry matter (DM), ash, crude protein (CP), ether extract (EE) and crude fibre (CF) determination. Sample preparation for mineral analysis.
