Influence of the country of origin and linear affiliation on the lifetime milk production of Holstein cows in resource-saving technology

Abstract

The productive longevity of cows is a rather complex integral trait, which is determined by both genetic and environmental factors. Among the first ones, the origin of the animals and the lineage of the parents have a significant impact, due to the effective breeding, subject to strict adherence to the system of selection and assessment of animals by breeding value. Therefore, the studies carried out in the aspect of the paternal influence of origin and lineage on the indicators of lifetime productivity of dairy cattle are relevant and motivated. In this regard, the purpose of the study was to determine the proportion of the dispersion effect of the origin and lineage of Holstein cows on the lifetime milk production at industrial milk production technology.
