Biological completeness of protein and its role in farm animals feeding

Purpose. To study the biological completeness of feed protein, including green mass cereal and leguminous fodder crops. find out role their aminoacid composition for farm animals feeding. Methods. Sampling was carried in accordance with State Standard Ukraine ISO 6497:2005, determination content moisture other volatile substances – 6496:2005, nitrogen crude protein 7169:2010. The amino acid determined on AAA500 ion-exchange automatic analyzer. Results. Cereal grain proteins are characterized by a relatively low lysine, threonine, corn tryptophan. richest source essential aminoacids among plant feeds is soybean meal, which contains, average, 43% protein. complex use sunflower rapeseed meal maximally balances nutrition the. But this raw material should be checked non-protein to confirm its natural origin. For ruminants, crops valuable feed, because it reaches 12% tillering phase, but decreases two times earing phase. In legumes, alfalfa chickweed, branching phase at level 27-29% terms absolutely dry matter, flowering –15-17%. individual aminoacids, exceeds 1.5-2 times. Conclusions. lysine triticale rye grains highest 3.6%, while wheat only 2.8%. An important condition solving problem animal multicomponent nature, ensures better balance aminoacids. times, lower compared legumes.
