摘要
以太湖猪为母本、抗应激皮特兰或杜洛克为第一父本、无氟烷基因的长大或大长公猪为第二父本的土四元杂交组合,经过示范与推广,结果表明:杜(皮)太二元母猪初配情期受胎率87.88%,经产母猪情期受胎率达到95.16%,窝均产仔13.72头,产活仔13.29头,35d断奶窝重112.99kg;长大杜(皮)太等四元杂交瘦肉猪日增重684.44g,料重比2.96∶1,瘦肉率61.91%;且无应激现象的发生,肉质正常,经济效益和社会效益非常显著。
The four-way cross combinations which were formed with Taihu pig as the female line and anti-stress Pietrain or Duroc as the first male line, and non- halothane gene L×Y or Y×L as the second male line were investigated. The results showed that the first-cycle conception rate of D(P)×T yelt was (87.88%), fecundation rate of sow 95.16%, pigging 13.72 per litter, pigging live piglet 13.29 per litter and 35 d weaning weight of litter 112.99 kg; the average day gain of (L×Y)×[D(P)×T] double cross pigs was 684.44 g, feed/gain 2.96:1, lean percentage 61.91%. Moreover there was normal meat quality and no stress in the four-way cross pig, and good benefit was created.
