Abstract
This study was undertaken to investigate the time required for post partum (pp) uterine involution in Turkish Awassi ewes with single and twin births. This will lead to asses the most appropriate time for insemination that ensure the highest fertilization rate as well as to avoid endometritis. This study carried out at sheep and goat improvement station/ state board of agricultural researches in Agargof (25km western of Baghdad( during the period of January to April, 2009. This trial involved 30 ewes (15 with the single births and 15 with twin births) of 2-4 years old and 40-75 kg live body weight. The diameter of uterine horn was significantly decreased in ewes with single births from 63.87±1.27 mm at the first week pp to 11.53±0.56 mm at seventh week pp. Concomitantly, diameter was also decreased in ewes with the twin births from 62.07±31.1mm at first week pp to 11.93±0.55mm at seventh week pp. The thickness of endometrium was obviously reduced in ewes with the single (from 5.87±1.27 to 1.00±0.00 mm ) and twin births ( from 5.66±0.27 to 1.00±0.00 mm) for the first and seventh weeks pp respectively.In conclusion, the uterine involution in Turkish awassi ewes ewes occurred, 35 days pp. Thus, it is possible to inseminate ewes after this period to achieved highest fertilization rate and to avoid endometritis.
