METHOD OF DETERMINING AND FORECASTING ECONOMIC BENEFICIAL QUALITIES OF CATTLE BEEF COWS Russian patent published in 2013 - IPC A01K67/02 

FIELD: agriculture.

SUBSTANCE: invention relates to breeding and selection of cattle of meat productivity and can be used in pedigree and commercial beef cattle breeding. The method comprises methods of inter-breeding, inter-herd selection, which provide a simplified pedigree evaluation and a more reliable selection of cows with high milk productivity contributing to an increase in body weight of weaned calves, that lead to better efficiency of feed consumed, characterised by the index of production value (IPV) of up to 7% indicating a low, and more than 8% of the high economically useful properties of cows of meat production. The calculation of the IPV is calculated as follows: where D_1,2,3 is the annual demand of meat cow for the feed in the first, second and third calving, depending on its live weight; N_1,2,3 is the live weight of calves at the age of 205 days, obtained from meat cow, respectively, in the first, second and third calving; 100 is the number of percent; n is the members of the sampling.

EFFECT: method provides a simplified pedigree evaluation and more reliable selection of cows with high milk productivity contributing to an increase in body weight of weaned calves.
