A total of 204 quail chicks aged one week (Coturnix coturnix Japonica) were used. They were divided into four groups each containing 51 quail chicks. Diets having normal (3000 kcal/kg) and low (2700 kcal/kg) metabolizable energy level were supplemented with 0 and 100 mg/kg L-carnitine. Diets were formulated to be isonitrogenic. The experimental period lasted five weeks. L-carnitine supplementation to the diets having normal energy level did not affect the live weight at the end of the experiment, total live weight gain, feed intake per one kg live weight gain and carcass yield but increased total feed intake (p<0.01) and decreased serum cholesterol level (p<0.01). The values of live weight at the end of the experiment were increased (p<0.01) and feed intake per one kg live weight gain (p<0.01), the serum levels of cholesterol (p<0.01) and triglyceride (p<0.05) were decreased by L-carnitine supplementation to the low energy diets. As a result, L-carnitine supplementation to the diets of low energy level have positive effects on the performance and decrease the levels of serum cholesterol and triglycerides of Japanese quails.eninfo:eu-repo/semantics/closedAccessblood parameterscarnitinefattening performancequailArticle542127132WOS:000254709400010N/A
