Estimation of genetic parameters for sire pig breeds using purebred and crossbred information

Original language description

Genetic parameters were estimated for Czech sire pig breeds from purebred and crossbred information. The data set contained 10315 records from station test (traits: VCS - valuable cuts and ADGS - average daily gain from 30 to 100 kg) and 71728 records from field test (traits: ADGF - lifetime average daily gain, LMF - lean meat contents). The following breeds were included in the analysis: Duroc, Belgian Landrace, Hampshire, Pietrain, Czech Meat pig and a sire line of Large White. A four-trait animal model was used for the calculation of genetic parameters running VCE under LINUX. The effects of breeds and crosses were modelled by linear regression on the gene proportions from individual breeds. The following heritabilities were estimated: VCS 0.56?0.019, ADGS 0.32?0.004, ADGF 0.21?0.005, LMF 0.42?0.008. Estimates of genetic correlations were: VCS-LMF 0.52?0.025, ADGS-ADGF 0.34?0.024.
