温氏不同配套系肉猪生长性能比较

Comparisons on growth performances of commercial pigs of Wens synthetic lines

摘要: 为比较温氏不同配套系肉猪性能，对WS501、WS401和SH301肉猪进行生长性能和肉质测定。结果表明，3种配套系肉猪各阶段生长速度差异不显著（P>0.05），WS501料重比较低，比其他2种配套系低0.047~0.115，后期优势明显；在大群表现中，WS501料重比和饲养时间有一定优势；屠宰试验中，WS501肉猪在宰后胴体直长、肋骨数、膘厚和HGP估测瘦肉率方面有一定优势，肉质差异不显著。

Abstract: 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.
