THE DEPENDENCE OF SIMENTALS MILK PRUDUCTIVITY ON THE BODY ITEMS MEASUREMENTS AFTER THEIR FIRST CALVING
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.
