Flashcards
Energy Feedstuffs
Energy Feedstuffs
Ingredients added to diets to increase energy content, typically high in readily digestible carbohydrates (CHO) and lipids.
Cereal Grains
Cereal Grains
Grains that are high-yielding and used in animal feed depending on price; characterized by variable fiber, low crude protein (CP), high phosphorus (P), and low vitamin content.
TDN (Total Digestible Nutrients)
TDN (Total Digestible Nutrients)
A measure of the digestible energy content in feedstuffs, calculated by subtracting fecal, urinary, gas, and heat losses from gross energy.
Study Notes
- Energy feedstuffs are added to diets to provide readily digestible carbohydrates and lipids.
- They are commonly included at high levels in livestock diets for rapid growth and finishing.
- Energy feedstuffs are characterized by low fiber, low to moderate protein, and high total digestible nutrients (TDN).
Cereal Grains
- Cereal grains have high yields.
- They are mainly for human consumption.
- Their use in livestock depends on price.
- Cereal grains vary in fiber content.
- They typically have low crude protein (CP).
- Phosphorus (P) content is high in cereal grains.
- Vitamin content is minimal and examples of cereal grains include barley, oats, rye, rice, corn, and sorghum.
