Abstract

Genetic gain in the population under breeding depends on genetic variability of the trait, reliability of breeding values estimation​​, selection intensity and length of generation interval. In the Czech Republic 31 breeds of sheep is currently involved in performance recording, from which 16 breeds are evaluated by ​​estimates of breeding values ​​using the BLUP Animal Model methodology. In the group of breeds with combined production the highest genetic trend can be seen in the Romney breed, who benefited from a relatively large recorded population kept in large herds and under comparative farming systems. In the group of terminal sire breeds there is particularly visible the superiority of the genetic trend in Suffolk breed compared to other meat sheep breeds.
