Periodical Change in the Carcass Composition of Chicks after Switching over the Diet to Lipogenic or Lipolytic Diet

Abstract

Periodical change in carcass composition of young chicks was determined after switching over the lipogenic diet to the lipolytic diet or vice versa. It was found that change in carcass fat level is rapid and reversible. When the lipolytic diet is switched to the lipogenic diet, carcass fat increases gradually and reaches to an apparent equilibrium after 12 days with fiducial limits from 17 to 9 days. When the lipogenic diet is switched to the lipolytic diet, carcass fat decreases to reach to an apparent equilibrium after 7 days. The lipolytic or lipogenic effect of diet is not simply due to the change in supply of dietary energy to the chicks.
