Study Notes
Animal Nutrition
- Feeds and forages are essential components for animal diets and include various nutrients necessary for growth and development.
Carbohydrates (CHO)
- Carbohydrates are primary energy sources for animals, classified as simple or complex sugars.
- Lignin is indigestible, negatively affecting the digestibility of fiber and protein.
- Whole grain cereals, such as barley, are rich in starch, primarily in the forms of amylose and amylopectin, which are located in the endosperm.
Energy, Protein, and Fibre Sources
- Energy sources include grains and fats, which provide high-caloric diets necessary for growth and maintenance.
- Protein sources in livestock diets include grass and cottonseed meal, providing essential amino acids.
- Fibre supports digestive health and gut function in animals.
Fat and Energy in the Diet
- Fats, primarily triglycerides, are composed of glycerol and three fatty acids, serving as a concentrated energy source.
- Simple triglycerides contain identical fatty acids, whereas mixed triglycerides consist of different fatty acids.
- Dietary fat aids in the absorption of fat-soluble vitamins and provides essential fatty acids.
Digestion of Fat
- Fat globules are challenging to digest in the stomach, requiring movement to the small intestines for further breakdown.
- Pancreatic lipase, activated by bile, facilitates the emulsification and breakdown of fats into fatty acids.
Protein Structure and Function
- Proteins are made from amino acids, which can be categorized into essential and non-essential groups.
- Essential amino acids include arginine and histidine; non-essential amino acids include alanine and glycine.
- Amino acids are broken down into ammonia, which is converted to urea for excretion when in excess.
Metabolism and Measurement of Energy in Ruminants
- Digestible Energy (DE) refers to the fraction of feed energy that is absorbed and utilized by the body, excluding energy lost in feces.
- Understanding the partitioning of feed energy helps optimize ruminant diets for efficient nutrient utilization.
