Abstract |
A research was conducted
to explore the effects of various levels of L-Carnitine in diet on
carcass characteristics and some serum parameters in female broiler
chickens. A total of 480 one-day old female broiler chicken (Ross 308)
were randomly allocated to 4 dietary treatments (6 replicates with 20
birds in each) in a completely randomized design. Treatments included
were control and the addition of various levels of L-Carnitine at level
of 100, 200 and 300 mg/kg in diets. The results showed that 300 mg/kg L-Carnitine
in diet decreased live body weight, carcass, thigh, and intestinal
weight (P<0.05). However, all dietary treatments decreased breast weight
compared to control diet (P<0.05). In addition, no significant
difference was observed in carcass yield and relative organ weights. The
serum triglyceride decreased significantly in treated groups. Aspartate
aminotransferase (AST), alanine aminotransferase (ALT) and albumin
increased significantly (P<0.05) in group fed 300 mg/kg L-carnitine. In
conclusion, the addition of L-Carnitine in diets had no positive effects
on carcass traits in first 10 days of age.
