Abstract

The research was performed in Shahumyan “Agroservice” OSC cattle pedigree farm. The verification of the performed selection and mate selection by mathematical analytical method confirms that, by the targeted breeding of newborns obtained by the use of the bulls of Austrian Swiss breed, in the first birth of F2 generation it’s possible to increase the average productivity of the given herd from 2500 kg to 5734 kg. Thus, we suggest applying diagram 1 for the purposes of maintaining and improving the Brown Caucasian breed. Within the framework of the program of cattle breeding development in the Republic of Armenia for the period 2019-2024, established by RA government decree N 327-L of March 29, 2019, it’s been intended to replenish the herds with pedigree cattle of valuable production-economic features, instead of animals of unknown origin, unfit for reproduction and of low productivity, and to develop the pedigree work. It’s known that the cattle breeding in the Republic is performed with the generation obtained by free mating with underdeveloped bulls of low productivity. For this reason, underdeveloped calves of low living mass are born, and the considerable part of them are bred in insufficient conditions of feeding and stall housing, thus impeding the renewal and replacement of herds with heifers that meet the requirement of the breed first class living mass.
