摘 要: 以中国优良地方猪种——二花脸猪为母本,用新美系杜洛克、德系抗应激皮特兰、加系双肌臀大白猪和新丹系长白猪等西方瘦肉型猪种作为父本进行土四元配套杂交组合试验,并与杜长大洋三元杂交组合进行比较.结果表明,除生长性能外,二花脸猪土四元杂交组合在繁殖性能和肉质特性方面有突出表现,甚至优于杜长大,尤其是以长大杜二组合的杂交效果较为理想. The performance is studied of the double cross combinations [(L×Y)×(P×E), (L×Y)×(D×E), (P×D)×(Y×E)], formed from Erhualian pig as dam line, the new Duroc of USA, anti-stress Pietrain of Germany, double muscle Large Yorkshire of Canada and the new Landrace of Danmark as sire lines, and compared with that of D×(L×Y) three-way crossing combination. The results show that except for growth capability, reproduction performance and meat quality of the Erhualian double cross combinations are superior to that of D×(L×Y) three-way cross combination, especially in (L×Y)×(D×E) combination.
