COMMON CAUSES OF REDUCED FERTILITY IN COWS IN SOME DISTRICTS OF SALAH- ADDIN

This study was designed to determine the incidence rate of some fertility problems that occur in cows in some districts of Salah AL-Din province. Data were collected from the records of the documentation of the coming cases to the veterinary clinics in ALDhuluiya and Al-Tuz in Salah-addin province. The results of the statistical data showed that cases of dystocia, retained fetal membranes and metritis were the highest incidence of other genital problems in local Iraqi cows, while the incidence of uterine and vaginal prolapse was less than the incidence of other cases. The system of breeding and the quality of food used have the greatest effect on the proportion occurrence of various reproductive problems in local Iraqi cows. ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ــــــــــــــــــــــــــــــــــــــــــ ـــــــــــــــ Keyword: fertility, uterine prolapse, dystocia, metritis. نيدلا حلاص ةيضقا طعب يف راقبلاا يف ةبوصخلا ضافخنلا ةعئاشلا بابسلاا زُاظ يٗذلا رًْ فاًْ ذ٘لْرلاّ ححازجلاّ ٌٖطاثلا ةطلا عزف ٕزط٘ثلا ةطلا ح٘لك دٗزكذ حؼهاج قازؼلا ٕرذح ي٘سح ل٘خد ح٘ذا٘حلا ءا٘و٘كلاّ حّٗدلااّ حجلسفلا عزف ٕزط٘ثلا ةطلا ح٘لك دٗزكذ حؼهاج قازؼلا ل٘ػاوسإ َللإا ذثػ نث٘ه ذ٘لْرلاّ ححازجلاّ ٌٖطاثلا ةطلا عزف ٕزط٘ثلا ةطلا ح٘لك دٗزكذ حؼهاج قازؼلا ٖهًْ قداص راشت – حٗزِجولا ءا٘حلاا عزف ٕزط٘ثلا ةطلا ح٘لك دٗزكذ حؼهاج لا قازؼ vetbashar1981@gmail.com ةصلاخلا لكاشه ضؼت زّذح ةسً حفزؼول حسارذلا ٍذُ دووص حتْصخلا حلاص حظفاحه ح٘ضلا ضؼت ٖف رامتلاا ة٘صذ ٖرلا يه لك ٖف حٗزط٘ثلا خافصْرسولا ٔلا حهداملا ح٘ضزولا خلااحلا ك٘ثْرت حصاخلا خلاجسلا يه خاًا٘ثلا غوج نذ . يٗذلا ساثرحاّ جدلاْلا زسػ خلااح ىا ح٘ئاصحلاا خاًا٘ثلا جئارً درثثا . يٗذلا حلاص حظفاحه ٖف سْطلاّ ح٘ػْلضلا ٖئاضل ولا ي٘ح ٖف ح٘لحولا ح٘لازؼلا رامتلاا ٖف ٓزخلاا ح٘لساٌرلا خلااحلا ح٘مت يه زّذح حثسً ٔلػا دًاك نحزلا باِرلاّ حو٘ش زثكلاا ز٘ثارلا مذخرسولا ءاذغلا ح٘ػًّْ ح٘تزرلا ماظٌل ىا . خلااحلا ح٘مت يه اثّذح حثسً للا لثِولا ّ نحزلا بلامًا حلاح دًاك لساٌرلا لكاشولا زّذح حثسً ٔلػ ح٘لحولا ح٘لازؼلا رامتلاا ٖف حفلرخولا ح٘ . ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــ Introduction Fertility problems are the most common problems affecting reproduction and production in cattle (1). Where reproductive problems lead to significant economic losses in the dairy industry because of the low number of born calves, delayed uterine involution and an increase in calving interval, resulting in reduced milk production, increased costs due to veterinary services and early culling of cattle (2). Therefore, reproductive management plays a very important role in cattle herds, that is any factor causes delay in pregnancy in cows directly reduces both milk production and the number of calves produced per cow per year, increasing the likelihood of herd replacement to reduce economic losses (3). Among the main reproductive problems that have a direct effect on the reproductive performance of cows are Euphrates Journal of Agriculture Science01(3): 73 77 , (2018) Dhaher et al.
