| Abstract | ||||
| Crossbreeding is considered a simple approach to improve poultry productivity depending on heterosis. As such, this experiment was conducted to use this phenomenon to increase meat yield in the local strains through crossing with broiler chicken. Sharkasi chicken (Nana) and Cobb parents (CC) were used as source for fertilized eggs required in this study. All possible mating combinations between the two strains were made to produce offspring (CC, NaNa, Nana, and nana); crosses (NaC and naC) and reciprocal crosses (CNa and Cna). The obtained chicks were wing banded, brooded in a floor pens under standard environmental conditions and fed ad libitum during the experimental period. Body weight as well as feed consumption was recorded at 0, 2, 4, 6, and 8 weeks of age to evaluate growth performance. At the end of the experiment (8 weeks), represented birds from each genotype were taken and slaughtered for carcass measurements | ||||
