Effect In-Ovo Injection (MethioGrow) Liquid Methionine in Broiler Breeder Eggs On Hatching Characters and Growth Performance
Abstract
Amino acids could be use due to its positive effects on several physiological and biochemical parameters, which key adapting function of metabolic processes during early development. Methionine is typically the first-limiting amino acid for protein requirement in poultry diets. Investigators are shown that Methionine concentrations in the blood plasma, and tissue of newly hatched control chicks were lower than those of chicks that received amino acid mix in egg The present study was conducted to study the effect of injecting methionine on the chicks growth performance, and immunoglobulin (IgG and IgA). Fertile 375 eggs of (Ross-308) broiler breeder strain were obtained at 30 weeks of age from Kosar Company, Taq Taq/Erbil. All eggs were weighted, incubated, and distributed randomly into five treatments. Our results indicate the egg injection with MethioGrow have significantly effect the body weight, feed conversion ratio, hatchability and Immunoglobulin’s (IgG, IgM) at 7 and 17 days old. But feed intake was not significant affected by adding the MethioGrow.Key words: Methionine, Ovo injection, hatchability.
