Comparative analysis of genomic evaluation results of stud bulls and assessment of the race quality

The article provides data on the differences in the assessments of the quality of raceand genomic evaluation of stud bulls. Zootechnicians and breeders choose bulls forthe reproduction of the herd, based on the genomic forecast of different countries. Acomparative analysis of the assessments results of stud bulls by the quality of raceand by genome was carried out on the basis of the artificial insemination enterprise Joint Stock Company "Udmurt Breeding Work". The study involved more than 70Holstein bulls of different lines. On average, the forecasts for genomic assessmentand the assessment of the quality of race by the level of milk yield, as well as by thequality indicators of milk, practically coincide. However, if we consider the forecast formilk yield in the context of lines, then there are differences in the genomicassessment and assessment of the quality of race in some lines. According to thequalitative characteristics of milk, the differences are significant in the section oflines, depending on the assessment. Thus, the study showed that genomicevaluation of the stud bulls can be used to predict the qualitative characteristics ofrace, but it is necessary to take into account the characteristics of each line.
