Abstract
Aim: This experiment was conducted to
evaluate the effect of L-carnitine supplementation on growth
performance, nutrient utilization and nitrogen balance in broilers
fed with animal fat.
Materials and Methods: 80 day-old Cobb commercial broiler
chicks were randomly assigned into two dietary treatment groups
with four replicates of ten chicks each. The diets were
isonitrogenous and isocaloric. The birds in both the control (T 1)
and treatment group (T2) were fed with a diet having 5% animal
fat, while the treatment group (T2) was supplemented with 900 mg
of L-carnitine. The birds were fed with standard broiler starter
ration up to 4 weeks of age and finisher ration up to 6 weeks of
age.
Results: The average body weight (g), cumulative feed intake
(g) and cumulative feed conversion ratio belonging to groups T 1
and T2 at 6th week of age
were 2091.25 and 2151.11, 3976.49 and 4171.68, 1.97 and 1.96
respectively. The percentage availability of the nutrients of two
experimental rations T1
and T2
was 68.23 and 68.00 for dry
matter, 58.72 and 55.98 for crude protein, 73.85 and 71.35 for
ether extract, 34.19 and 33.86 for crude fiber, 79.18 and 79.59
for nitrogen free extract, 70.24 and 70.03 for energy efficiency
and nitrogen balance (g/day) were 2.35 and 2.39, respectively.
Conclusion: This study
suggests that the supplementation of 900 mg L-carnitine in diet
with added animal fat had no effect on growth performance,
nutrient utilization, and nitrogen balance of broilers.
Keywords: animal fat,
broilers, performance and nutrient utilization, l-carnitine.
