【 摘 要 】

The aim of the study was to estimate the effects of theCAPN316 ,CAST282, GH L127V ,GHR F279YandA257Gon  milk yield, fat and  protein  yield and content on daughters produced by dairy sires. 24 dairy sires were 100% Holstein (14), 100% Brown Swiss (5) and Holstein mixed with another dairy breeds (5). Analyses included data on 32733 daughters for 2014-2017 years. Molecular genetic analysis was performed by PCR-RFLP. Statistical analysis revealed that population was on Hardy-Weinberg equilibrium. SNPsF279YandA257Gwere not in linkage disequilibrium ( r 2 = 0.029,D’= 0.074), because linkage of certain alleles was observed only in 7.4% of cases (D’).C -allele of SNPCAPN316was strongly associated with protein content, despiteC -allele  of SNPCAST282showed negative association with milk, fat and protein yield. Daughter milk performance traits (DMPTs) for SNPCAPN316corresponded toCC>CG>GGpattern, except variations in milk and fat yield (kg). For SNPCAST282Milk, fat and protein yield (kg) were significantly higher forCGthan forCCgenotype.C -allele for SNPL127Vshowed significant association and differences between genotypes with DYDs for fat yield (kg) – 20.45±5.53 ( P <0.01) and content (%) – 0.13±0.06 ( P <0.05),T -allele for SNPF279Vwas not significantly associated with any trait studied andA -allele for SNPA257Gsignificantly associated with milk and fat yield (kg) for DMPTs/DYDs 1988.33±419.93/-269.69±89.92 ( P <0.01) and 84.30±15.64/-8.33±3.87 ( P <0.05). Results of this study reveal and support known advantages of SNPs studied in panels and selection programs.
