Influence of bulls on the reproduction indicators of daughters taking into account their productivity
The main objective of the development of dairy cattle breeding is to increase
the breeding productive characteristics, taking into account the preservation of the
reproductive qualities of animals. The research was conducted on the basis of data
from the breeding plant for black-and-white cattle breeding OOO “Zazerkalie” in the
Vologda region. Bulls-improvers were determined by the complex of selected traits,
taking into account the linear affiliation: Meson 3097402441; Retirement 11720463 of
the line of the R. Sovering (1st lactation of daughters). It is recommended to use the
best breeding material (seed of breeding bulls, breeding young), which allows the next
generation to get a reliable improving effect on the selected characteristics.

The impact and results of using sires in dairy cattle populations in the Vologda region
Studies were conducted on controlled populations of dairy cattle of
Ayrshire, Kholmogory, Yaroslavl, black-and-white breeds of breeding farms in the
Vologda region. It has been revealed that the sires of domestic selection have a greater
degree of influence on the productive indices of their daughters than foreign ones do.
The calculation of the breeding value of bulls in terms of their daughters’ productivity
has been carried out, and on the basis of a comparative analysis the best producers
in the context of selections having the greatest impact on the productivity indices of
descendants have been determined.
