Genetic trends for backfat thickness and time on test for Landrace and Large White breed in Vojvodina

The aim of the paper was to analyse genetic trends for backfat thickness and time on test in Landrace and Large White pigs in Vojvodina. Data included 5, 872 data records from field test for Landrace and 5, 934 for Large White from 2008 to 2014. Residual maximum likelihood method was used to obtain variance components for analyzed traits. Breeding values were estimated using animal model. In order to obtain genetic trends, breeding values were summarised by year. Genetic trends were negative and favourable for backfat thickness in both breeds, while there was no substantial changes in genetic trends for time on test.
