Abstract

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.

Summary

Introduction

At the moment the technology development and selection should be a basic requirement for the creation of such animal genotypes, which combine high production capabilities and quality with an enhanced ability to Express them in terms that do not meet adequately the physiological needs of the organism, that is, the genotype of the animals must be assigned to the whole complex of characteristics, first and foremost, the ability to develop their productive capabilities in the presence of a large number of stress factors in increasing and developing intensive technologies. An important problem of beef cattle breeding is the development of advanced management technologies, as well as breeding methods This will allow us to improve the production of high-quality products at an accelerated pace and create new types of cattle that meet the requirements of intensive and cost-effective beef production and breeding of repair young animals. In this regard, the chosen direction of scientific research in beef cattle breeding meets the urgent requirements of beef production and rearing of repair young animals in farms of various directions and organizational structure in the Russian Federation. 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
