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.
