Abstract
The present study was conducted to determine the effects of supplemental dietary L-carnitine at different levels on growth performance, carcass traits, and composition of edible meat in Japanese quail. One hundred sixty-eight 1-d-old Japanese quail chicks were fed the same basal diet that was supplemented with 0 (control), 30, 40, or 50 mg L-carnitine/kg of diet. The effects of dietary L-carnitine supplementation at different levels on body weight gain, cumulative feed intake, and feed conversion ratio of Japanese quail did not differ. Supplementation of L-carnitine to Japanese quail diets from 0 to 35 d of age did not affect the hot and cold carcass yields and the relative values of heart, liver, gizzard, and abdominal fat. Levels of supplemental dietary L-carnitine did not affect the dry matter, moisture, CP, or ether extract content of the total edible meat in Japanese quail chicks.
