Abstract

This study was done to investigate the inbreeding content and its relationship with some productive traits in Moghan agro-industrial company Holestein cows using 17966 Holestein cows pedigree data from 2007 to 2016. For preparing and editing of data, estimate of inbreeding coefficient and traits regression content from inbreeding, Fox pro, Excel, CFC and Wombat softwares were used, respectively. 32.12 percent of total animals were inbred. Inbreeding coefficient average for total population and inbreed animals in this study was calculated 0.56% and 1.85%, respectively. Inbreeding depression for 1% increasing of inbreeding for milk production and number of days in milk were estimated -15.14 kg and -1.60 day, respectively

Persian Title: بررسی ارتباط آمیزش خویشاوندی با برخی از صفات تولیدی در گاو¬های هلشتاین مجتمع کشت و صنعت مغان
Persian Abstract: این مطالعه به منظور بررسی میزان هم¬خونی و ارتباط آن با برخی از صفات تولیدی 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، برآورد ضریب هم¬خونی و محاسبه میزان تابعیت صفات از هم¬خونی به ترتیب از نرم افزار¬های Fox pro،Excel ،CFC و Wombat استفاده گردید. 12/32 درصد کل حیوانات هم¬خون بودند. میانگین ضریب هم¬خونی کل جمعیت و حیوانات هم¬خون به ترتیب 56/0 و 85/1 درصد برآورد شد. افت ناشی از هم¬خونی به ازای افزایش یک درصد هم¬خونی برای صفات میزان تولید شیر و تعداد روز¬های شیردهی، به ترتیب 14/15- کیلو¬گرم و 60/1- روز برآورد شدند.
