Study Notes
Non-Essential Nutrients
- Non-essential nutrients cannot be synthesized in sufficient quantities by the body to meet its needs.
- Essential nutrients must be obtained from the diet.
Feed Comparison
- Not all feeds are equal; varies in nutrient composition and digestibility.
- Chicken and rice provide different nutritional profiles.
- Grass and corn also differ in nutrient composition and digestibility.
Components of Nutrients in Feed
- Key components of feed: water, carbohydrates, proteins, lipids, vitamins, and minerals.
- Feed value is influenced by nutritional content, digestibility, palatability, and presence of anti-nutritional factors.
Animal Nutrition Issues
- Insufficient feed risks nutritional deficiencies, growth failure, and mortality.
- Excess feed can cause nutritional toxicity and health disorders.
- Disease stems from responses to internal/external factors; disorders signify structural or functional disruptions.
Livestock Classes and Feeding Methods
- Non-ruminants: Feeding can be restricted or provided ad libitum (free-choice).
- Monogastrics include poultry, which have specific dietary needs.
- Ruminants may vary in size affecting their feeding strategies.
Introduction to Animal Nutrition
- Nutrition is the science of how food nourishes organisms and affects health.
- Focuses on feed, feeding strategies, maintenance, productivity, and health implications.
Nutrition Processes
- Key processes: procurement, ingestion, digestion, metabolic functions, absorption, and excretion.
- Nutrient interactions influence physiological responses in the body.
Nutritional Requirements for Animals
- Requirements include maintenance, growth, and production (e.g., reproduction, products like meat and milk).
- Maintenance ensures the animal's vital functions without weight gain or loss.
Growth and Production Factors
- Growth is influenced by species characteristics, age, and individual variability.
- Production needs include supporting muscle, bone, organ development, and reproductive processes.
Impact of Nutrition on Productivity
- Individual genetic potential, species, age, and management factors influence productivity.
- Nutrition quality and quantity are essential in realizing genetic potential.
Nutrients Overview
- Nutrients are compounds vital for bodily functions and include macronutrients (water, minerals, carbohydrates, proteins, lipids) and micronutrients (vitamins, minerals).
- Different nutrients serve various roles: energy provision, tissue building, and regulation of bodily processes.
