Genetic Evaluation of Fleckvieh and Holstein Heifers per their Origin and Ancestors’ Productivity

Abstract

Investigations indicate that genetic ability of milk productivity in the heifers of Holstein breed makes 10377.5 kg, the average milk yield amounts to 6965 kg, which makes 67.1 % of the overall genetic ability, while the amount of milk fat + milk protein is 494.6 kg. The same indices in the heifers of Fleckvieh breed are 9819.5 kg, 6226 kg, 64.4 % and 446.6 kg respectively.
According to the indices of the ancestors’ milk productivity registered in the breeding cards the mating applied for the breeding of heifers of Holstein breed has a number of advantages over that of applied for the Fleckvieh breed. Thus, to ensure high milk productivity, it is recommended to raise animals of Holstein breed in the farms of Armenia.
