This study highlights the use of European breeding bulls in the selection of breeding stock of Swiss cattle in Uzbekistan in order to improve the productive qualities of cows and create highly productive families. In experimental herds, milk yields of mature cows exceed the requirements of the breed standard by 935 - 1219.4 kg, the ancestors of families are 1627 - 1816 kg higher than the requirements of the breed standard, which indicates their high genetic potential.
