Principles of Animal Nutrition and Feed Technology: A Comprehensive Guide for Veterinary Science
Understanding Animal Nutrition and Feed Technology
Animal nutrition is the science of providing animals with the nutrients they need for optimal growth, development, and well-being. Feed technology involves the processing, preservation, and storage of animal feed to ensure its quality and availability.
Essential Nutrients for Animals
Animals require a wide range of nutrients, including carbohydrates, proteins, fats, vitamins, and minerals. Essential nutrients are those that the body cannot synthesize on its own and must be obtained from the diet.
Urea Supplementation in Ruminants
Urea is a non-protein nitrogen source that can be used to supplement protein in the diets of ruminants. It is converted to ammonia in the rumen, which can be utilized by microorganisms for protein synthesis.
Apparent Digestibility of Feed
Apparent digestibility refers to the proportion of a nutrient in feed that is absorbed and utilized by the animal. It is lower than true digestibility, which accounts for the fraction of nutrients that are lost in feces.
Assessing Protein Quality in Non-Ruminants
The quality of protein in feedstuffs for non-ruminants can be assessed using various methods, including amino acid profiles, biological assays, and in vitro digestibility techniques.
