Study Notes
- There are eight classes of feedstuff.
Eight Classes of Feedstuff
- Dry roughages
- Succulent roughages include pasture and range grasses.
- Ensiled roughages
- High energy concentrates
- Protein concentrates
- Minerals
- Vitamins
- Additives
Dry Roughages
- Bulky feed with low weight per unit volume
- High crude fiber content with low protein and fat digestibility
- To be classified as a roughage, a feed must contain > 18% crude fiber and 70% total digestible nutrients.
Dry Roughage Examples
- Hay
- Straw & Chaff
- Sugarcane bagasse
- Corn cobs
- Cottonseed hulls
Succulent Roughages
- Pasture grasses (natural & cultivated)
- Legumes (fresh)
- Tree leaves
- Roots & tubers
Silages & Haylages
- Made through a fermentation process with high moisture feed from plant material
- Silage has 20 – 45% dry matter (DM)
- Haylage has 50 -75% DM
High Energy Concentrates
- These include cereal grains and milling by-products.
- Molasses
- Animal & vegetable fat
Protein Concentrates/Supplements
- Contain more than 20% Crude Protein (CP)
- Oil seeds and their meals (e.g., SBM, Copra meal)
- Animal, avian, and marine sources (e.g., Fish meal, meat meal)
- Milk and milk by-products
- Brewery and distillery by-products
- Urea, ammonia
Vitamins & Mineral Supplements
- Vitamins and minerals must be added by sources that animals can absorb.
- The vitamin concentration in plant and animal tissues varies greatly.
- Vitamin concentrations in plants are affected by harvesting, processing, and storing.
- Animal livers and kidneys are good sources of vitamins.
Feed Additives
- Non-nutritive ingredients are added to stimulate growth or performance or improve feed efficiency.
- Added in very small quantities
- Examples are antibiotics, antifungals, antimicrobials, probiotics, buffers, colors, flavors, hormones, and enzymes.
