Abstract

The present study was conducted to determine the effects of different levels of L-Carnitine (Lohman 20% Carnitine) and methionine on female broiler chickens in a completely randomized experimental design with 12 treatments and 3 replicates in 36 pen with three levels of L-Carnitine (0, 75 and 150 mg.kg) and four levels of methionine (85, 100, 115 and 130 NRC%). At 42 d, 2 chickens from each replicate were randomly taken for measurements of body weight, serum triglyceride (TG), cholesterol (CHOL), low density lipoprotein (LDL), high density lipoprotein (HDL), glucose (GLU), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The highest body weight (P<0.05) was found at the level of 115% methionine + 150 mg/kg L-Carnitine with beneficial effect on serum Glu, TG, AST and ALP. In conclusion, we opined that the best combination was 115% methionine and 150 mg/kg L-Carnitine for optimum production in broiler.
