Abstract

This research was done to estimate the inbreeding coefficient in Moghan agro-industrial company Holestein cows using of 17966 Holestein cows pedigree data from 2007 to 2016. For preparing and editing of data, pedigree analysis and inbreeding coefficient estimation, Fox pro, Excel, Pedigree and CFC softwares were used respectively. Inbreeding coefficient average for total population and inbreed animals in this study was calculated 0.56% and 1.85%, respectively. The lowest and highest inbreeding amount in this herd was observed 0.78% and 37.5%, respectively. The results of this research showed, in compared with other similar populations, average of inbreeding coefficient was lower in this herd that could be related to factors like preventing of very close inbreeding and tending to controlled mating.

Persian Title: برآورد ضریب هم¬خونی در گاو¬های‌ هلشتاین مجتمع کشت و صنعت مغان
Persian Abstract: این پژوهش به منظور برآورد ضریب هم¬خونی در گاو¬های هلشتاین مجتمع کشت و صنعت مغان با استفاده از اطلاعات شجره¬ای 17966 رأس گاو هلشتاین از سال 1386 تا 1395 انجام شد. برای آماده سازی و ویرایش داده¬ها، تجزیه شجره و برآورد ضریب هم¬خونی، به ترتیب از نرم افزار¬های Fox pro،Excel ، PedigreeوCFC استفاده گردید. میانگین ضریب هم¬خونی کل جمعیت و حیوانات هم-خون به ترتیب 56/0 و 85/1 درصد برآورد شد. کمترین و بیشترین مقادیر هم¬خونی در این گله به ترتیب 78/0 و 5/37 درصد مشاهده گردید. نتایج این پژوهش نشان داد که میانگین ضریب هم¬خونی در این گله نسبت به جوامع مشابه دیگر کمتر بود، که می¬تواند با عواملی مانند جلوگیری از آمیزش¬های خویشاوندی خیلی نزدیک و تمایل به جفت¬گیری¬های کنترل شده در ارتباط باشد.
