Comparisons on growth performances of commercial pigs of Wens synthetic lines

In order to compare growth performance of different commercial pigs of Wens synthetic lines, growth performance and meat quality of WS501, WS401 and SH301 hogs were determined. The results showed that there was no significant difference in growth rate between different groups. WS501 had a better feed conversion ratio (FCR), which was 0.047-0.115 lower than those of two other synthetic lines, especially at last stage. In the large group of pig production, WS501 had the advantages in FCR and feeding days. In slaughter test, WS501 had the advantages in carcass length, rib number, fat thickness and HGP estimated lean meat percentage, and there was no significant difference in meat quality.
