| چکیده | ||
| هدف این تحقیق، بررسی تفاوت پاسخ عملکرد تولیدمثلی بره میشها و میشهای مسنتر لری بختیاری به فلاشینگ بود. به این منظور از میشهای سالم یک گله 55 رأس بره میش و 245 رأس میش بالغ انتخاب شدند. هر یک از بره میشها یا میشهای بالغ به طور تصادفی در یکی از سه تیمار: بدون فلاشینگ(شاهد)، فلاشینگ با دانه جو و فلاشینگ با دانه جو و چربی قرار گرفت. جیره فلاشینگ از دو هفته قبل از معرفی قوچ به گله تا سه هفته پس از آن در اختیار میشها قرار داده شد. نتایج نشان داد که، بر خلاف میشهای بالغ، نرخ آبستنی و نرخ زایش در بره میشها تحت تاثیر تیمار قرار گرفت (0/05 >p). در بره میشها، تعداد بره متولد شده به ازای هر رأس میش در معرض آمیزش در تیمار فلاشینگ با دانه جو و چربی بالاتر از دو تیمار دیگر بود (0/05>p) در صورتی که در میشهای بالغ، اختلاف میشهای تیمار فلاشینگ با دانه جو و چربی از نظر تعداد بره متولد شده به ازای هر رأس میش در معرض آمیزش تنها با تیمار شاهد معنی دار بود (0/05 >p). طول دوره آبستنی در بره میشها و میشهای بالغ در تیمارهای مختلف اختلاف آماری معنی داری نداشت. نرخ دوقلوزایی در بره میشها و میشهای بالغ تحت تاثیر تیمار قرار گرفت اما میزان این تاثیر در بره میشها بیشتر بود (به ترتیب 0/01>p و 0/05>p). بنابراین به نظر می رسد که در میشهای بالغ فلاشینگ و در بره میشها فلاشینگ با چربی باعث افزایش عملکرد تولیدمثلی میگردد. | ||

| چکیده [English] | ||
| The objective of this study was to evaluate the reproductive responses to different flushing treatments in Lori-Bakhtiari ewe-lambs and mature ewes.For this purpose, a total of 55 ewe-lambs and 245 mature ewes in a flock containing 400 ewes, were selected and randomly divided into three groups. The treatments were as: 1; no flushing (control), 2;flushing with barley and 3;flushing with barley and fat. Flushing diets were offered from 2 weeks before to 3 weeks after ram introduction. The conception and parturition rates in ewe-lambs, were significantly affected by treatments (p<0.05) so that, ewe-lambs in the treatment 3, had the highest conception (95 %) and parturition (95 %) rates. The number of lambs born per ewe exposed, in ewe-lambs at the treatment 3 (122 %) was higher than (p<0.05) the treatment 2 (94 %) and the control (88 %) but, in mature ewes, statistical differences (p<0.05) were found just for ewes at the treatment 3 and the control ewes (118 vs. 102). The gestation length for ewe-lambs and mature ewes at all treatments, were similar. The multiple lambing rate was higher (p<0.01) in ewe-lambs at the treatment 3 (29 %) than two other treatments. But, differences between mature ewes at the treatments 3 and 2 for multiple lambing rates (23 and 18 % respectively), were not statistically significant. It seems therefore that, in Lori-Bakhtiari sheep, flushing of mature ewes with barley grain (with or without fat) and flushing of ewe-lambs with barley grain and fat supplement, will increase their reproductive performance. | ||
