The aim of the study was to analyse the relationship between DGAT1 K232A polymorphism and bulls’ breeding value for five reproductive traits – age at first insemination, calving-to-conception interval, calving-to-first service interval, non-return rate in heifers, and non-return rate in cows.The investigation was conducted on 264 Polish Black-and-White (Polish Holstein-Friesian) bulls from the active...
The aim of the study was to analyse the K232A polymorphism in the acyl CoA:diacylglycerol acyltransferase gene (DGAT1) and to estimate the effects of lysine (K) and alanine (A) encoding variants on milk yield and composition in cattle. A total of 100 Jersey cows was tested for DGAT1 genotypes using the PCR-RFLP technique. The K and A allele frequencies were 0.83 and 0.17, respectively.Effect of the...
