摘  要：
选用麻城黑山羊(Ⅰ)为对照组,波尔山羊×麻城黑山羊(Ⅱ),麻城黑山羊×波麻F1(Ⅲ),波麻F1×波麻F1(Ⅳ),波尔山羊×波麻F1(Ⅴ)5个组,以放牧加补饲的方式育肥,试验期90d,期间于第0、90d称重,试验结束时于每个组选择12头屠宰并进行胴体性能和肉质性能的分析。结果表明:①杂交后代的日增重较麻城黑山羊组均有所提高,其中Ⅱ、Ⅲ、Ⅴ组的日增重极显著高于麻城黑山羊(P<0.01)。②杂交后代的胴体性状较麻城黑山羊有了较大提高,其中Ⅱ、Ⅴ组的屠宰率和净肉率分别显著、极显著高于麻城黑山羊(P<0.05,P<0.01),Ⅱ、Ⅳ组的肉骨比显著高于麻城黑山羊(P<0.05);Ⅱ、Ⅴ组的眼肌面积极显著高于麻城黑山羊(P<0.01);③各组间主要肉质性能除麻城黑山羊的pH24显著高于Ⅱ、Ⅳ组(P<0.05)外,差异均不显著(P>0.05)。结果提示,Ⅱ组是肉羊生产理想的杂交组合,Ⅴ组可用于进一步培育麻城黑山羊新品系的研究。

摘  要：
In order to study improvement and new strain breeding of Macheng black goats, an experiment was conducted to investigate fattening performance and meat quality traits among Macheng black goats and its crossbred progenies. All experimental goats were divided into five groups, which were Macheng black goats group (Ⅰ for CK), Boer×Macheng black goats group (Ⅱ), Macheng black goats×BMF1 group (Ⅲ), BMF1×BMF1 group (Ⅳ), Boer×BMF1 group (Ⅴ). After rearing of 90 days by grazing and supplementary feeding and weighing on the 1st and 90th day, twelve goats were respectively slaughtered to determine the carcass traits and meat quality in different groups. The results showed that: fattening performance of crossbred progenies were higher than that of group Ⅰ, average daily gain of group Ⅰwas lower than that of group Ⅱ, Ⅲ and Ⅴ (P<0.01); ② the carcass traits of crossbred progenies were greatly increased, the dressing percentage and net meat percentage of group Ⅱ and Ⅴwere significantly greater than that of group Ⅰ (P<0.01, P<0.05), respectively; meatbone ratio of group Ⅱ and Ⅳ was significantly higher than that of group Ⅰ (P<0.05); Loin-eye area of group Ⅱ and Ⅴ was significantly higher than that of group Ⅰ(P<0.01); ③ main meat quality of different group were similar (P>0.05), except that pH24 of group Ⅰ was higher than those of group Ⅱ and Ⅳ (P<0.05). These finding of this experiment showed that group Ⅱ was suitable for the potential of meat-type goats, and group Ⅴ could be used to further research on new Macheng black goats strain breeding.
