Association of selected genes with milk fat in two breeds of cattle
Original language description
The aim of the work was to evaluate genotype and allelic frequencies of selected genes affecting milk fat synthesis and to investigate possible association between gene polymorphisms and milk production traits. For this purpose, the analysis of DGAT1 (diacylglycerol acyltransferase 1), FASN (fatty acid synthase) and LEP (leptin) was carried out on 754 dairy cows distributed in five farms located in the Czech Republic. The tested animals were divided into three groups: Czech Fleckvieh (CF; n=266), Holstein (H; n=329) and crossbreds (CB; n=159, with 87% of CF crossbreeds). The dominant genotypes for all observed groups were: AA genotype for DGAT1 gene (0.962, 0.973 and 0.912; p<0.01), GG genotype for FASN gene (0.770, 0.662 and 0.774; p<0.01), and MM genotype for LEP gene (0.714, 0.783 and 0.826; p>0.05). The evaluation of milk production traits in the first lactation has shown, that the highest fat yield was found out in dairy cows with genotypes AA (327 kg), AG (330 kg) and MM (328 kg). The differences were statistically significant only for DGAT1 gene. These results suggested, that milk from dairy cows with DGAT1 gene A allelic variant would be more appropriate for the production of dairy products (butter, cheeses).
