| 摘 要： | 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。 |

| Abstract: | 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. Four evaluating items, which were average annual profit of each replacement gilt, profit of each standardized commodity pig, quantity of sows corresponding 1 000 standardized commodity pigs and intramuscular fat content of commodity pigs, were used to optimize these crossbreeding systems. Result was that Duroc×(Large White × Jihe White Specilized mother line B)was the best one. |
