چکیده

به منظور شناسایی ریسک فاکتورهای موثر بر سقط جنین در جمعیت گوسفند و بز در جنوب کرمان دو پرسشنامه تهیه شد که پرسشنامه اول مربوط به ریسک فاکتورهای انفرادی و محیطی مربوط به مادر و جنین و پرسشنامه دوم مربوط به ریسک فاکتورهای مربوط به دام ها و گله بود. تحلیل داده ها با استفاده از نرم افزار Minitab و به روش رگرسیون انجام و ضریب همبستگی و درجه معنی داری برای متغیرهای پیش بین ارائه شد. نتایج نشان داد که میانگین سن مادران سقط جنین کرده 33/4 ماه و میانگین سن جنین سقط شده برابر با 3/5 ماه بود. هم چنین واکاوی داده ها نشان داد که بیش ترین میزان جنین های سقط شده مربوط به سن 3 تا 4 ماهگی با حدود 57 درصد و کم ترین میزان سقط در جنین های کم تر از یک ماه و با حدود 6 درصد بود. 80 درصد سقط ها در داخل جایگاه، 34 درصد سقط ها دوقلو و 81 درصد سقط ها در آب و هوای گرم اتفاق افتاد. سیستم نگه داری و منطقه در میزان بروز سقط جنین تاثیر معنی داری داشت به طوری که دام های نگه داری شده در سیستم آزاد و دام های نگه داری شده در مناطق گرم به طور معنی داری میزان سقط جنین بیش تری داشتند. با افزایش سن دام ها و تعداد دام های گله میزان سقط جنین به طور معنی داری افزایش یافت. تغذیه دستی و استفاده از مواد ضدعفونی کننده باعث کاهش میزان سقط جنین به طور معنی داری شد و با کاهش نسبت آخور به دام سقط جنین به طور معنی داری افزایش پیدا کرد.

چکیده [English]

In order to identify the risk factors affecting abortion in sheep and goat population in southern of Kerman, two questionnaires were prepared, the first was related to individual and environmental risk factors related to mother and fetus and the second questionnaire was related to risk factors related to livestock and herds. Data analysis was performed using Minitab software and regression method and the correlation coefficient and significance for the predictor variables were presented. The results showed that the mean age of mothers was 33.4 months and the mean age of aborted fetuses was 3.5 months. Data analysis also showed that the highest rate of aborted fetuses occurred at the age of 3 to 4 months with about 57% and the lowest rate of abortions occurred in fetuses less than one month old with about 6%.80% of abortions on the farm, 34% of abortions were twins and 81% of abortions occurred in hot weather. The results of this study showed that the maintenance system and the region had a significant effect on the incidence of abortion and in animals that kept in the open system and animals kept in warm areas had significantly higher abortion rates. With increasing the age of livestock and the number of livestock, the rate of abortion increased significantly. Manual feeding and use of disinfectants significantly reduced the rate of abortion. With decreasing ratio of manger to livestock Abortion increased significantly.
