Creation of optimal selection-technological model cow of production type based on Holstein genotype

Abstract

Based on the recommendation of adaptation the ICAR a regional management model of high-yielding genetic resources of animal husbandry in dairy farming was developed, which has been tested in the ICAR Secretariat and at the national level of the Russian Federation. For developing the optimal selectiontechnological model cow of the production type based on Holstein genotype the interaction of the control assistant and evaluation service, laboratory for milk quality selection control and genetic control was used. Using highly productive bulls of Holstein breed is one of the main directions into improvement the productive and technological characteristics of the dairy cattle of local genotypes. In the recent years, thanks to extension of the livestock genetic research, it was considered useful to monitor the distribution of genetic abnormalities BLAD, CVM, DUMPS, BC, BY, FXID; studies of lethal haplotypes HH1, HH3, HH4, HH5, AH1, associated with impaired fertility, lack of cholesterol HCD and shortened spermatic filament syndrome ARMC3B. An integrated approach allows developing recommendations to the selection of parental pairs, to improvement the exteriorconstitutional features, and excluding from the breeding process the male and female parent; who are genetic abnormalities carriers associated with impaired cow fertility.
