[Changes in the protein content and their amino acid makeup in the muscles in feeding rats corn with an increased lysine content]. / Zminy vmistu bilkiv ta ikh aminokyslotnoho skladu u m'iazakh pry hodivli shchuriv kukurudzoiu z pidvyshchenym vmistom lizynu

The biochemical indexes of the rat muscles were studied as affected by maize with a higher content of lysin. It is shown that a month after an increase in the body weight and mass of muscles are more pronounced in the rats which were fed maize with a higher content of lysin. The latter, evidently, is due to an increase in the content of sarcoplasmatic proteins, RNA, as well as macroergic compounds, ATP and creatine phosphate, in the muscle of the animals under experiment. The qualitive composition of muscles proteins changes in these animals. A rated gain in essential amino acids is observed as compared to the control group. Hence the feeding of the maize with a higher content of lysin to animals may increase the feed value of meat products.
