چکیده:   (380 مشاهده)
در این پژوهش از رکوردهای طول عمر 26991 راس بره حاصل از 405 راس قوچ و 8114 راس میش نژاد مهربان که طی
سال­های 1360 تا 1390 به­وسیله سازمان جهاد کشاورزی استان همدان جمع­آوری شده بود، استفاده شد.
به منظور تعیین عوامل ثابت برازش شده در مدل آماری (سال تولد، ماه تولد، تیپ تولد، سن مادر، اثر گله، جنس بره و متغیر کمکی وزن تولد بره و اثرات متقابل بین آنها) از رویه GLM نرم­افزار SAS استفاده شد. اثر متقابل سال تولد-جنس بره و تمامی اثرات ثابت به جز نوع تولد، سن مادر و متغیر کمکی وزن تولد بره به صورت خطی بر طول عمر معنی­دار (001/0P< ) بودند. جهت برآورد پارامترهای ژنتیکی صفت طول عمر از روش بیزی با استفاده از نمونه­گیری گیبس و نرم­افزار TM1 استفاده شد. برای تمام تجزیه­های بیزی  از 500000 نمونه، با دوره­ی گرم کردن 100000 و با فواصل 100 از یکدیگر استفاده شد. میانگین وراثت­پذیری مستقیم و مادری طول عمر در تجزیه­های مختلف به ترتیب بین 16/0 تا 22/0 و بین 13/0 تا 15/0 برآورد شدند. میانگین همبستگی بین اثر ژنتیکی افزایشی مستقیم با اثر ژنتیکی مادری 54/0- تا 61/0- بدست آمد .با توجه به برآورد پایین وراثت­پذیری صفت طول عمر، می­توان نتیجه گرفت، به منظور افزایش طول عمر، باید با بهبود شرایط محیطی و تصمیمات کاربردی و مدیریتی، طول عمر بره­ها را افزایش داد
