Abstract:

Indigenous chicken breeds in developing countries have diverse benefits to rural economy as a source of high-quality animal protein. However, there are few reports on the evaluation of economic traits in Egyptian indigenous breeds. Hence, this study aimed to investigate growth performance, carcass characteristics, body measurements and meat quality traits in two indigenous breeds of chickens (Benha line and Golden Montazah) versus Rhode Island Red as a reference worldwide breed. Besides, a time series expression profile of somatotropic axis genes including GH and IGF-1 and their plasma level concentrations were investigated. Benha line chickens (BL) revealed the highest improved estimates of growth performance, carcass characteristics and meat quality traits. In the same manner, it displayed the highest levels of hepatic GH and IGF-1 and muscle IGF-1 gene expression compared to Rhode Island Red (RIR) and Golden Montazah (GM) chickens. Accordingly, BL exhibited the highest levels of plasma IGF-1 and the lowest levels of plasma GH. This result suggests the direct association between growth performance, carcass characteristics and levels of IGF-1 gene expression in the selected chicken breeds. BL is a superior Egyptian genotype with candidate productive traits and competing characteristics, it could be used widely as a proven ancestor of commercial hybrid breeds.
