چکیده

ناباروری ازعوامل اصلی زیان اقتصادی و هم چنین تاثیر گذار بر بازده تولیدمثلی در دامداری ها می باشد. هدف از این مطالعه بررسی عوامل موثر بر ناباروری در گاو های شیری می باشد. اطلاعات مورد نظر شامل وضعیت تغذیه، تعداد شکم، وضعیت زایمان، فصل زایش، جفت ماندگی و متریت از پرونده گاو های ارجاعی به بیمارستان دامپزشکی دانشگاه شهید چمران اهواز جمع آوری شد. تجزیه و تحلیل اطلاعات با استفاده از آزمون رگرسیون لوجیستیک و مربع کای انجام شد. شانس زایمان طبیعی برای گاوهایی که از جیره غذایی مناسب استفاده می کردند 5/020 برابر گاوهایی بود که تغذیه ضعیف داشتند (0/05>p).  تاثیر وضعیت زایمان و جفت ماندگی بر ابتلا به متریت نیز معنی دار بود (0/05>p). نسبت شانس ابتلا به متریت برای گاوهایی که به سخت زایی مبتلا شده اند نسبت به گاوهایی که زایمان طبیعی داشته اند 31/419 بود. هم چنین این نسبت برای گاوهای جفت مانده نسبت به گاوهای که جفت خود را در زمان طبیعی دفع کرده اند 1/377 می باشد. توجه به عوامل مستعد کننده مانند تغذیه، سخت زایی، جفت ماندگی و متریت حتی در گاوهای بومی می تواند نقش به سزایی در کاهش ناباروری در گاو شیری داشته باشد.

چکیده [English]

Infertility is one of the main causes of economic losses and also affects the reproductive performance in dairy farms. The aim of this study was to consider the factors affecting infertility in dairy cows. The information, including nutritional status, parities, parturition, calving season, retention of placenta and metritis, was collected from the case of the referred cows to the Veterinary Hospital  of Shahid Chamran University of Ahvaz. Data analysis was performed using logistic regression and chi-square tests. The chance of a normal parturition for cows used a proper diet was 5.020 times more than of poorly fed cows (p<0.05).The effect of dystocia and placental retention on metritis was also significant (p<0.05). The chance ratio for metritis in cow with dystocia at parturition time compared to cows with normal parturition was 31.419. Also, this ratio for cows with retained placenta compared to normal cows was 1.377. Prevention the predisposing factors such as poor nutrition, dystocia, retention of placenta and metritis complex, even in native cows, can play a significant role in reducing infertility in dairy cows.
