Milk productivity of offspring depending on the milk productivity of mothers of holstein cows

\nAs a result of scientific research, the milk productivity of Goldsmith cows was studied depending on the productivity of their mothers. Under conditions of homogeneous feeding and conservation, the milk productivity of their mothers in cows of group III was 4545.0 kg, in cows of group II - 5189.0 kg, in cows of group I - 321.0 kg, and the amount of milk received by their daughters for 1 lactation was 520.3 kg or 15.9% (P>0.999) and 196.0 kg or 5.5% (P>0.95), respectively, the fat content in milk is 18.3 kg or 14.8% (P>0.999) and 6.6 kg or 4.9% (P>0.99), the protein content in milk is 16.2 kg or 14.5% (P>0.999) and 6.0 kg or 4.9% (P>0.95)., A milk mixture with a content of 4% is 456.0 kg or 14.7% (P>0.999) and 165.0 kg or 4.9% (P>0.95), the milk ratio is 70.5 kg or 9.1% (P>0.999) and 19.5 kg or 2.4%, the average daily milk content is 1.7 or 15.7%. (P>0.999) and 0.7 kg, or 5.9% (P>0.95), were high.\n
