| Abstract: |
Simple Summary: Poultry breeding programs are established to ameliorate the genetic potential of domestic birds through a selection process and crossbreeding programs. In this context, crossbreeding has been considered as an essential tool to produce favorable genotypes, which are affected by different genetic resources and non-genetic factors. Thus, the aim was to evaluate the impact of crossing white and brown quail lines on growth performance, carcass traits, and the relative expression of growth-related genes. The crossbred WBQ quail line (male white female brown) exhibited a significantly greater dressing percentage and better feed conversion ratio (FCR), as well as higher mRNA expression of growth hormone receptor (GHR) and insulin-like growth factor-1 (IGF-1) genes. |
