    DESCRIPTION & OBJECTIVES

     

    This post-graduate level course is aimed at nutrition of dairy animals for better milk production and health. It focuses on milk production problems related to nutrition and process of ingestion, digestion and metabolism of different essential nutrients in dairy animals. To apprise students about nutritional requirement and nutritional management of dairy animals

     

    INTENDED LEARNING OUTCOMES

  • Students will be able to explain the physiology of udder and mechanisms of milk production.
  • Students will understand the role of nutrients requirements for milk production.
  • Nutritional management of breeding bulls, dairy cows at different physiological stages
  • Metabolic Health related aspects of dairy animals.
  • COURSE CONTENTS

    Theory: Digestive physiology: Digestion and absorption; Factors affecting digestion; Feed resources: Fodders, crop residues and concentrates; Nutritional requirements of different classes of dairy animals; Requirements for maintenance, growth, production, and reproduction; Feeding systems: Feeding on complete feed, fodder plus supplementation, silage, haylage and hay; Feed formulation for calves, heifers, dry, pregnant and lactating cows; Nutritional management of breeding bulls; Minerals and reproduction in dairy. Feeding of high yielding cows; Bypass proteins, lipids and feeding frequency; Feeding management of dairy animals under tropical conditions; Nutritional disorders and deficiency diseases; Nutrition and milk quality. Feed additives and feed supplements; efficient usage of urea and other NPN sources in dairy feeding.

    PRACTICAL

    Digestion trials; Measurement of digestion kinetics; Digestibility through indicator methods; computerized feed formulation for different classes of animals; Hay and silage preparation.
