4) crossbreeding system
杂交繁育体系
1.
Three foreign line pigs, Duroc, Landrace and Large White, a local breeding line, Jihe White Specilized mother line B and a pure local line, Taihu pigs were chosen to build crossbreeding system on quality pigs through simulating biology ecnomics process.
选用杜洛克、长白、大白3个国外引进品种,冀合白猪专门化母系B1个国内培育品系,以及1个地方品种太湖猪,模拟杂交繁育体系的生物经济学过程,构建了优质猪的杂交繁育体系,并以每头后备母猪平均每年的利润、每头标准化商品猪的利润、每1000头标准商品猪相对应的母猪头数和商品代出栏猪肌内脂肪含量(肉质指标)4个评价指标对杂交繁育体系进行了优化选择,结果在4种杂交配套组合中,杜洛克×(大白×冀合白猪专门化母系B)经济效率和商品代猪肉质最优。

The results show that the 3 most efficient crossbreeding systems are Hamshire×(Yorkshire × Landrace), Hamshire×(Landrace× Yorkshire) and Hamshire ×(Yorkshire,Landrace)rot.
在特定的繁育方法内，繁育体系的效率随着亲本品种数量的增加而增加；亲本品种数量固定时，终端杂交繁育体系的效率高于终端轮回杂交，而终端轮回杂交繁育体系的效率又高于轮回杂交繁育体系；同时条本品种组分对繁育体系的生产效率具有重要作用。
