| The study was conducted on 113 local Iraqi ewes, presented in Al- Jazeera - Al-budiab area which belongs of Al- Anbar province. The age of the animals ranged from 2-5 years. The animals were fed on free rearing and given 2% of B.W. conc. and the water were given ad libtum. The animals were divided into three groups according to the colors of the face and body. The first group (No. = 40) have Brown color of the face and white color of the body. The second group (No.=46) have a Black color of the face and white color of the body. The third group (No. =27) have a Black color of the face and spotted body. Chi-square test were used for analysis of data. The results showed that the total conception rate were 49.5% (56/113), while the total twinning rate was 7.07% (8/113). The results also showed that there is an increase in conception rate in the 2nd and 3rd group (54.3%, 55.5%) as compared with 1st group (40%). There was a significant difference (P≤0.05) in conception rate between 2nd, 3rd and the first group. Twining rate was 6.6%, 13.6 and 36.6% in the 1st, 2nd and 3rd groups respectively. There was a significant difference (P≤0.05) in twinning rate between different groups. The fertility rate were 42.5%, 60.8% and 70.3% in the lst, 2nd the 3rd groups respectively. The Birth rate were 106.2%, 112% and 126.6% in the 1st, 2nd and 3rd group respectively. There was a significant difference in birth rate (P≤0.05) between the 3rd group and the other groups. It was concluded from this study that Iraqi local breed ewes having Black face with spotted body showed the best reproductive performance | ||
