- Abstract
There are presented the results of the studying productive qualities of Holstein cows of various origins. The material for the research was cattle of the Holstein breed of German selection-Society of limited liability "Dastocom" and French selection - Society of limited liability "Holstein". Milk yield of cows in the herd of LLC "Dastocom" for the first lactation averaged 8851 kg of milk. The milk productivity of Holstein cows of French selection (LLC "Holstein") for the first lactation averaged 6334 ± 34.7 kg of milk. At cattle of the Holstein breed of German selection (LLC "Dastocom"), a high level of heritability for milk yield (mother-daughter) was found, which amounted to 0.756. The greatest influence on the fat content in the milk of the first-calving cows of LLC "Dastocom" was exerted by paternal ancestors (h2 = 0.39). For the entire analyzed population of cows-heifers of LLC "Holstein", milk yield and fat content in milk were largely determined by heredity (h2 = 0.24-0.49) and (h2 = 0.44-0.32), respectively.
