Role of nature and number of parturition in the incidence of uterine prolapse in dairy cows in north Iraq

Abstract

This study was conducted in the specialized vet. clinic in reproductive diseases and artificial insemination, in Balad region in Saladin province in the northernIraq.

    This study included72 cows have uterine prolapse, the number of multipara cows that have uterine prolapse was 49( 68.06%). While the primipara cows with uterine prolapse were23(31.94%), with significant difference between two groups at (<0.01).

    This study showed that the difficult male parturitions in multipara cows was 23(71.88%)and the normal male parturitions in this group was 9(28.12%). These results were  significantly difference between two groups at( p<0.01). The total percentage of uterine prolapse that accompanied the male parturitions in multi para cows was 65.31%. While the number of difficult  female parturitions  was 12(70.59%) in this  group of cows, and the number of normal female parturitions was 5(29.41%). With significant difference at (P<0.01).and the total percentage of uterine prolapse associated with female parturition in the same cows was 34.69%. the study indicated that the number of difficult male parturitions in primipara cows was 9(69.23%), and the number of normal male parturitions was 4(30.77%) in this group of cows , with significant difference between two groups at(P<0.01).and the total percentage of uterine prolapse accompanied male parturitions in primipara was 56.53% .While the number of difficult female parturitions in primipara cows was 7(70%), and the number of normal female parturitions was 3(30%). These results were significantly difference at (P<0.01). with total percentage of uterine prolapse related to female parturitions in this group was 43.47%.

    Conclusion: it is concluded from this study that the number of parturitions increases the probability of incidence of uterine prolapse, hence the uterine prolapse is more commonly in multipara cows, and the dystocia for both sexes of fetus play an important role in its incidence.
