Abstract

The effect of .36, .86, and 1.24% dietary lysine on the rate of turnover of liver proteins in chicks in the first 15 days of life was studied. Half-lives of 18.4 +/- .2, 5.7 +/- 1.0, and 6.3 +/- .1 days corresponding to 26.6 +/- .2, 8.2 +/- 1.4, and 9.1 +/- .1 days turnover time and 3.8 +/- .02, 12.3 +/- 1.9, and 11.0 +/- .2% net daily degradation for liver proteins of chicks fed .36, .86, and 1.24% dietary lysine, respectively, were obtained. Turnover rate of the liver proteins increased in a manner similar to the gain in body weight with the levels of dietary lysine.

摘要

研究了日粮赖氨酸含量分别为0.36%、0.86%和1.24%对雏鸡出生后前15天肝脏蛋白质周转率的影响。日粮赖氨酸含量为0.36%、0.86%和1.24%的雏鸡肝脏蛋白质的半衰期分别为18.4±0.2天、5.7±1.0天和6.3±0.1天，相应的周转时间为26.6±0.2天、8.2±1.4天和9.1±0.1天，每日净降解率分别为3.8±0.02%、12.3±1.9%和11.0±0.2%。肝脏蛋白质的周转率随日粮赖氨酸水平的升高而增加，其增加方式与体重增加相似。
