The objective of this study was to estimate genetic parameters for total number born (TB), stillbirth (SB), mummy (MUM), and litter birth weight (LBW) in Landrace (LR) and Large White (LW)pigbreeds. Data were collected from swine commercial herd at Pak Chong district, Nakhon Ratchasima Province. A total of 99,250 records during 2004 to 2011 were used to analysis.Genetic parameters and breeding values were estimated by animal model withmultipletrait analysis by BLUPF90-Pig PAK 2.5 software. The results were shown that estimated heritability for all traits were low. Next step to improve these traits, the selection intensity, should be increase selection index and concentrate with raising management during pregnant and farrowing. The genetic correlations... |
