| Abstract | ||
| The investigation was carried out at Sheep and Goat Breeding Station, State Board of Agricultural Research, Ministry of Agriculture in Agargouf, 25 km west of Baghdad, during May, 2009 to June, 2011. The objective of this study was to evaluate and compare reproductive performance characteristics between local Awassi and Turkish Awassi breeds (150 ewes each breed group). The two flocks reared under semi-intensive production system, were better feeding under sanitary control out of diseases, and suitable housing were provided. The rams joined ewes during mating season of 2009/2010. Early embryonic mortality, fertility (percentage of ewes lambed out of ewes exposed to rams), twinning percentage (number of ewes bearing twins, expressed as a percentage of the ewes that lambed), lambing percentage (number of lambs born per ewes exposed to rams), mortality (lambs died expressed as percentage of lambs born), prolificacy at lambing (lambs borne per ewes lambed), prolificacy at weaning and total weights of lambs weaned per ewe exposed. Imported Turkish Awassi ewes had significantly (p<0.01) surpassed local Awassi ewes by 11.3% in lambing percentage (114.6% vs. 103.4%).Imported Turkish Awassi ewes had significantly (p<0.01) surpassed local Awassi ewes by 15.3% in lambs weight/ewe lambed at weaning (25.35 kg vs 23.72 kg). It was concluded that imported Turkish Awassi ewes were superior to Iraqi Awassi in many physiological and reproductive traits under semi-intensive System so that It was recommended to distribute Turkish Awassi breed for accelerated lambing in semi-intensive production. | ||
