Abstract
The research was carried out in the Livestock Research Division / Nineveh Research Department to study the effect of four different treatments of Sex ratio male: female (1: 1, 1: 2, 1: 3 and 1: 4), using 477 birds at production age, for 10 weeks on the performance of the partridge. The results showed that 1: 3 treatment significantly increase (P <0.05) on other treatments 1: 1, 1: 2 and 1: 4 for daily egg production / female%. A significant increase (P <0.05) of 1: 1 treatment over other sex ratio treatments 1: 2, 1: 3 and 1: 4 appeared in weekly consumed feed. Also, there was a significant improvement (P < 0.05) in the treatment of the sexual ratio 1: 3 over the treatment of 1: 1 and mathematically on the treatments 1: 2 and 1: 4 in food conversion ratio (FCR) kg/dozen eggs. While the sex ratio treatments did not have a significant effect on fertility%, hatching%, hatching of fertilized eggs%, However, it was observed that the increase of female numbers in the treatment, led to decreased fertility and hatching rates, because the males may have a preference for certain females when mating. the sexual ratio did not affect mortality% or weight hatching.
