Abstract
The Iraqi local chicken is national wealth, so it is necessary to work on increasing knowledge of its fertilization capabilities. The current research aims to identify the local breeds that have fertility characteristics by studying the variance in semen quality and comparing it with some characteristics of the semen of other local breeds. Replicates of white breeds W, Black B, and striped BW were adopted at 60 weeks of age. Semen values according to the characteristics of colour, the volume of semen, number and concentration of sperm, percentage of abnormalities, live and dead sperm, and individual and collective motility. Semen colour for all breeds was pearly white, and there had been no big differences in the characteristics of semen size, sperm count, concentration, individual and collective motility, and percentage of dead sperm. While, the white and striped breeds significantly outperformed the black breed (P≤0.05) in the proportion of stay sperms. Black breed significantly outperformed the rest of the study breeds in the percentage of sperm abnormalities, as it turned out that the study breeds had good fertility characteristics compared to other local breeds.
