摘 要: 以中国优良地方猪种———太湖猪为母本,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,太湖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;尤其是长大杜太的总产仔数和产活仔数分别达到14.51和13.86头,肌肉失水率6.58%,均优于杜长大(P<0.01或P<0.05),且肌肉脂肪含量适中(3.32%),是较为理想的杂交组合. The performances of the double cross combinations [ (L× Y) ×( P × T), (L × Y) × (D × T), ( P × D) × ( Y × T) ], which were formed from Taihu 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, were studied and compared with that of three-way crossing combination D × ( L × Y). Except for growth capability, reproduction performance and meat quality of the Taihu double cross combinations were superior to that of D × ( L × Y) combination, especially in ( L × Y) × ( D × T) combination which is a more ideal combination with the higher litter size ( 14.51 ), survival litter size ( 13.86 ) and lower water loss (6.58%) compared with D× (L × Y) combination (P 〈0. 01 or P 〈0.05), and medium muscular fat (3.32%).
