Umanets D. Digestibility of fodder metabolism and productive qualities of quails at different levels of lysine and methionine in mixed fodder.

Object - quails of the Japanese breed of an egg direction of efficiency for a different level of a amino acid feed. The purpose - to establish optimum levels of lysine and methionine in mixed fodders of young quails and egg-laying quails of the Japanese breed for more efficiency uses of a forage and quality of production. Methods - zootechnical, biochemical and statistical. Novelty - consists in improvement amino acid a feed quails an egg direction of efficiency. It is received the new data on need quails in lysine and methionine on a level of a protein and energy in a diet. The data on features of influence amino acid a feed quails on digested forages, balance of nitrogen, safety of a livestock, morphological, biochemical and amino acid structure of their blood, a chest muscle of young growth and amino acid structure of eggs of female quails for the first time are received. Results of researches - are used in practice, educational process and research work. Branch - animal industries
