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.
