Abstract |
The present research was
carried out to investigate the effects of different levels of L-Carnitine
(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 day, 2 chickens from each
replicate were randomly taken for measurements of IgG and blood cell
counts.
Highest IgG, WBC, RBC, Hb and HCT was found in birds
fed 130% NRC + 150 mg//kg L-Carnitine. Lowest IgG, RBC, Hb and HCT were
observed in group of birds treated with 100% NRC + 0 mg/kg L-Carnitine.
Lowest WBC was observed in group of birds treated with 85% NRC + 0 mg/kg
L-Carnitine.
In conclusion, we opined that the best combination
was 130% NRC methionine and 150 mg/kg L-Carnitine for optimum immunity
and body defence against infectious diseases in female broilers.
