Study the Effects of Different Levels of Energy and L-carnitine on Meat Quality and Serum Lipids of Japanese Quail

B. Parizadian, M. Shams Shargh and S. Zerehdaran    

Abstract: Effects of various levels of energy and L-carnitine on meat quality and serum lipids of Japanese quail were examined. This experiment was carried out using 480 quails in a completely randomized design with two levels of energy (2900 and 3100 kcal kg-1) and three levels of L-carnitine (0, 250 and 500 mg kg-1) by factorial arrangement. Four replicates with 20 quails were allocated to each experimental treatment and birds were reared for 42 days. At the end of the experiment, two birds from each experimental unit were selected and after slaughter and separation of carcasses, thigh and breast samples were transferred to the freezer to asses meat quality parameters. The results showed that using of higher levels of energy increased the amount of blood cholesterol and triglyceride (p<0.05). The quails were fed with ration containing L-carnitine supplementation, had lower triglyceride in comparison with control group (p<0.05). Higher levels of energy increased the amount of crude fat and malonaldehyde in breast samples. The amount of malonaldehyde in breast samples after storage for 90 days and amount of crude fat and malonaldehyde in thigh samples after storage for 30 and 90 days were affected by different levels of L-carnitine, so that using of 250 mg kg-1 L-carnitine significantly reduced the amount of malonaldehyde in breast samples and crude fat and malonaldehyde in thigh samples (p<0.05). Therefore, it can be concluded that the supplementation of diet with L-carnitine has positive effects on blood triglyceride and meat quality in Japanese quail.
