Abstract
هدف از مطالعه حاضر غربالسازي پروفايل ژنتيکي ژن کاپا-کازئين ميان گاوهاي دو رگه فريسوال (سايوال × HF) پرورش يافته در هند بود. تعداد 200 گاو فريسوال براي HinfI RFLP بر اساس تعيين ژنوتيپ ژن کاپا-کازئيين مورد ارزيابي قرار گرفتند. ما مشاهده کرديم که تنها دو ژنوتيپ (AA و AB) در ميان جمعيت مورد مطالعه به ترتيب با فراواني ژنوتيپ 58/0 (تعداد = 117) و 24/0 (تعداد = 83) وجود دارند. فراواني الل مورد محاسبه براي A و B، به ترتيب 79/0 و 21/0 بود. رابطه ژنوتيپها با صفات توليد شير مشخص تأييد نمود که AB اثر معنيداري (P<0.05) روي توليد کل شير، توليد حداکثر، توليد در 300 روز و درصد SNF در مقايسه با AA دارد.
Abstract
The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117) and 0.42 (n=83), respectively. The calculated allele frequency for A and B was 0.79 and 0.21, respectively. Association of genotypes with certain milk production traits revealed that AB had significant (P<0.05) effect on total milk yield, peak yield, yield at 300 days and SNF% as compared to AA.
