Abstract | The selection of livestock ís based on breeding values (BV), which represent Ihe genetic value of each animal for a particular trait. The traits of interest are commonly chosen by a national breeding program for their biological or economic importance. In the Czech Large White pig population, the production efficiency is evaluated by lean meat content (LM%). However, this supposedly leads to unintended selection pressure on the LM% components: loin muscle depth (LD) and backfat thickness (BFT). Therefore, this work aimed to estimate genetic parameters for these two traits. For this purpose, data from 178,596 pigs between 2004 and 2020 were analysed. |
