Lysine-supplemented cottonseed

Cooked glandless cottonseed protein quality was superior to that of raw and roasted cottonseed. The roasting process adversely affected protein quality. Supplementation of roasted cottonseed with 0, 0.2, 0.4, 0.6 and 0.8% L-lysine indicated a peak PER response at 0.45%. The adverse effect of roasting on the protein quality of cottonseed was overcome by addition of L-lysine which made the protein... 

The protein composition of cereals is not snfflcient to sustain optimnm growth in most domestic animals. Thus, cereals are supplemented with protein meals that contain high amonnts of lysine and tryptophan. The most common protein meals are soybean, cottonseed, canola, and meat and fish meal. The use of meat and bone meal, and other animal protein meals snch as dried blood, is prohibited in several parts of the world because its consumption has been associated with mad cow disease.
