Evaluation of the quality of bulls-producers’ offspring according to the quality and testing their sons according to their own productivity

The purpose of the study is to evaluate the bulls- producers on the quality of offspring and test the sons according to their own productivity. Meat cattle breeding in the Republic of Khakassia is represented by Hereford breed. In 2014 a new type of Hereford cattle "Andrianovsky" was approved and adapted; it differs from basic in growth rate, the ability to store energy of growth for a long time without carcass deposition, adapted to year-round pasture keeping, allowing pro-ducing high-quality beef with 10-month pasture keeping. The evaluation of animals in the terms of the quality of offspring makes it possible to identify the best producers in the terms of breeding, i.e., those who, when selecting certain uterus, are able to produce higher-quality off-spring better than offspring of other producers. The analysis of the data obtained in the test of bulls on its own productivity shows the stability of selection charac-teristics and the assessment not only of breeding quali-ties of animals, but also their prediction of the appropri-ateness of using in breeding and commodity herds...
