Effect of the level of dietary lysine on turnover rate of liver protein in the chick.
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.
