Summary: The application of the BLUP method to evaluate Holstein-Friesian bulls showed advantage over the CC method. In breeding value evaluation of sires by the BLUP method, the possibility to eliminate the main systematic environmental influences is very significant. The systematic influences on the productivity of the first lactation cows were estimated at 36% for milk yield, 37% for fat yield and 23% for fat content. The relationship matrix model of breeding values of sires turned out to be better than the model with genetic groups. By crossing the Simental with red Holstein-Friesian breeds, the milk yield in lactation has increased for 637 kg and the fat yield for 24 kg. The heritability of the Lipizzaner horses for withers height, chest volume and cannon bone circumference varied from 0.49 to 0.80, 0.31-0.68 and 0.25-0.58, respectively. The BLUP model was applied for breeding value evaluation regarding the body measurements. Crossings concerning the sheep production showed that it is possible to increase the daily gains for 14-19% by means of this method.

Keywords: cattle, horse, sheep, genetic parameters, breeding value, BLUP method, crossing

Research goals: The aim of these researches is to find a suitable model of the BLUP-method which should provide a high accuracy of the cattle breeding values. The estimated results were of use in shaping the new suggestions and instructions for evaluation of bulls and cows. Quantitative genetic analysis of the morphological and reproductive parameters of various horse populations enabled the estimating of differences between the genetic groups and choosing the way of their genetic improvement. The crossings in cattle and sheep breeding indicated the possibility of increasing the meat and milk production by means of this method.
