Abstract

The linear estimate of black-motley breeding heifers has been carried out, an analysis of their milk products was done. It was found that the best animal results are general variety of heifers - 73,1 points, the worst diagnostic on udder is 61 points, and appendicular organs of heifers are 63,1 points. Milk products is 5419 kg per lactation, fat is 3.63%, protein is 3.2%. The determined coefficient of
correlation between general variety of heifers and milk yield of animals has been weak ,r = 0,13 and the average connection between productivity and assessment of the udder (r = 0,43) has been found.
