松辽黑猪生长发育性能研究

目的]为松辽黑猪新品系和吉松配套系选育优质肉猪新品种提供理论依据。方法]选取松辽黑猪,松野杂猪和杜长大三元杂交育肥猪各15头,分成3个组分别为S、Y和B组,组内设3个重复,每个重复5头猪,在同一条件下进行饲养试验,并对其生长发育性能进行测定。结果]S组松辽黑猪的胸围发育程度明显高于Y组松野杂猪和B组杜长大三元杂交猪,差异极显著（P〈0.01）,其他指标均差异不显著;Y组松野杂猪的增重速度、发育程度、屠宰率和产瘦肉率与B组杜长大三元杂交猪相比,差异均不显著。结论]在增重速度和产肉率方面,松辽黑猪新品系和松野杂猪新品种的选育是成功的。

Growth Performances of Songliao Black Pigs

Objective] To Provide a theoretical basis for breeding new pig varieties of high-quality pork from Songliao Black Pigs and Jisong commercial strains.Method] A total of 45 pigs including 15 Song-liao Black pigs,15 Song Wild Hybrid pigs and 15 Duroc-landrace-yorkshire pigs were divided into three groups,namely S,Y and B group.There were three repeats in each group,and five pigs in each repeat.The growth performances of all pigs were detected under the same feeding condition.Result] The chest circumferences...
