The greatest success in improving the breeding and productive
qualities of Hereford cattle can be achieved through the use of high-value
breeding bulls. The role of producers at the modern stages of beef cattle
breeding has increased dramatically, so the evaluation of bulls by the
quality of offspring has become an important breeding event to improve
and create highly productive herds of beef cattle. At the same time, the use
of bulls that are predisposed to various diseases or the deterioration of their
offspring can cause irreparable negative consequences for beef cattle
breeding. In the course of research work in the conditions of the farm,
studies were conducted to assess the quality of bulls-producers of the
Hereford breed of cattle. Evaluation of Hereford bulls by the quality of
offspring in farm conditions will increase the efficiency of herd
reproduction technology in beef cattle breeding, allow rational use of bulls,
get a high yield of calves (90-95%), organize the accuracy of accounting
for the origin of young animals, increase the level of breeding work to
improve the productive, breeding qualities of animals and create highly
productive herds of Hereford cattle in a shorter time.
