Study Notes
Introduction to Animal Nutrition
- Veterinary Zootechnics course focuses on animal nutrition principles for the first semester of S.Y. 2023-2024.
- Key course objectives include understanding nutrients, feeding management, and the importance of food in the animal industry.
Definitions
- Food/Feed: Material capable of being ingested, digested, absorbed, and utilized by animals.
- Nutrition: Processes involving the ingestion, digestion, absorption, and utilization of nutrients, promoting health and sound body structures.
- Nutrient: Essential chemical elements or compounds required for normal metabolism, including carbohydrates, proteins, lipids, minerals, vitamins, and water.
Functions of Nutrients
- Structural components of the animal body.
- Maintains health and wellness.
- Regulates metabolic processes: growth, cell activity, enzyme production, temperature regulation.
- Provides energy, which can be stored or used immediately.
Importance of Animal Nutrition in Industry
- Enhances nutrient-efficient livestock production.
- Improves safety and dietary quality of animal products for human consumption.
- Boosts health and welfare of farm animals.
- Example: Feed conversion rate for poultry meat has decreased by over 20% in 40 years.
Nutrient Classification
- Essential Nutrients: Cannot be synthesized by the body; must be included in the diet.
- Non-essential Nutrients: Produced by the body and do not need to be included in the diet.
Nutrient Requirements
- Minimum nutrient levels necessary for maintenance, growth, reproduction, lactation, and work.
Nutritive Value (NV)
- Refers to the composition and availability of protein, minerals, and energy in feed, as well as efficiency in energy utilization.
Ration and Balanced Ration
- Ration: Total feed allowance for an individual animal over 24 hours.
- Balanced Ration: Formulated to meet all nutrient requirements specific to a species and class of animal for maintenance and performance.
Nutrient Sources
- Most animal nutrition originates from plant sources; plants convert simple substances (CO2, water) into complex nutrients through photosynthesis.
