Study Notes
Principles of Animal Nutrition and Feed Technology
- Animal nutrition is pivotal for livestock and poultry health and production.
- Nutrients are crucial for maintaining animal health and enhancing productivity.
- Animals' body and plant composition includes essential nutrients with specific roles.
Nutritional Components
- Carbohydrates, proteins, and fats are primary nutrients with distinct functions.
- Water, including metabolic water, plays a vital role in overall health.
- Minerals (major and trace) and vitamins are essential for health; their requirements vary by species.
Feed Classification and Energy Measures
- Common feeds for livestock and poultry are classified based on availability and importance.
- Measures of food energy include gross energy, digestible energy, metabolizable energy, net energy, and total digestible nutrients.
Protein Evaluation
- Protein quality is assessed using biological value, protein efficiency ratio, and digestible crude protein.
- Calorie-protein ratio and nutritive ratio are used to evaluate protein sources.
Feed Technology Overview
- The feed industry involves processing concentrates and roughages to improve nutrient absorption.
- Techniques for enhancing low-quality roughages include various physical, chemical, and biological methods.
Feed Composition Terminology
- Dry matter refers to the non-water content of feed, calculated by subtracting water percentage from 100.
- Feed efficiency measures the conversion ratio of feed to animal production (meat, milk, eggs).
- Essential amino acids and fatty acids must be supplied through diet as they cannot be synthesized by the body.
Carbohydrates
- Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen; they serve as the primary energy source for animals.
- Functions include energy provision for muscle activity, fat oxidation, and metabolic stability.
Carbohydrate Classification
- Monosaccharides are single sugar molecules, categorized by carbon count: trioses (3), tetroses (4), pentoses (5), and hexoses (6).
- Complex carbohydrates involve digestion via microbial enzymes in the rumen.
Rumen Carbohydrate Digestion
- Initial breakdown converts complex carbohydrates into simple sugars, enhancing microbial enzymatic action.
- Short-chain volatile fatty acids (VFA) such as acetic, propionic, and butyric acid are major end products of carbohydrate fermentation in the rumen.
Rumen Gas Dynamics
- Gas production (approximately 30 liters/hour) varies with feed type; consists mainly of CO2 (40%) and CH4 (30-40%).
- Eructation is the primary method for gas release, with conditions like bloat resulting from gas accumulation.
Methane Production
- Produced by methanogenic bacteria, methane contributes to energy loss (approx. 7% of total feed energy) during digestion.
- Methane generation equates to about 4.5 grams per 100 grams of carbohydrate digested in ruminants.
