Abstract

There were studied the milk productivity and body items measurements of Simmentals in this work. The dependence of yield and quantity of milk fat on the indicators of cow-heifers' performance were established. The animals whose height at the shoulder is 136 sm and more, chest depth – 77 sm and more, width of chest – 53 sm and more, chest girt behind shoulders – 196 sm and more, skewed body length –163 sm and more, width of ribbing – 57 sm and more and metacarpus girt– 18,1 – 20,0 sm had the highest above named indicators.
