ANSC 1011 Lecture : NRC Feed Categories Notes
Document Summary
Less than or greater to 18% crude fiber-up to 50% Process of ensiling under anaerobic conditions; fermented plant materials. Common storage method for feed, but does not improve quality. 2. pasture, range plants, green forages: silages and baleage. Realtively immature, green and leafy, not much stems, free of mold and foreign materials. Legumes vs grasses- alfalfa and clovers usually higher quality than grasses: energy feeds. Examples: cereal grains such as corn, wheat and milo, by-products. Cereal grains- low protein quality, low in calcium, and moderate in. Plant sources- sbm (soybean meal), csm (cotton seed meal), cgm (corn gluetein meal) Plant source- primary from meal of oilseeds, usually more than 40% of protein. Purified amino acids or crystalline amino acids- bacteria fermentation by-products. Meals high in phosphorus but tied up with phytic-bound complex-enzyme phytase. First rate limiting amino acid- the first amino acid that restricts the performance of the animal.
