云岭黑山羊与波云F1代山羊的育肥及肉质性能的研究

通过对9月龄波×师F₁代、波×文F₁代、波×楚F₁代、师宗黑山羊、文山黑山羊、楚雄黑山羊进行育肥和屠宰试验，结果表明，在放牧＋补饲条件下，波×师F₁代、波×文F₁代和波×楚F₁代羊的平均日增重(分别为137.2、133.1和132.3 g)明显高于师宗黑山羊、文山黑山羊和楚雄黑山羊的平均日增重（分别为103.6、102.3和101.6 g），且差异极显著；在全放牧条件下，波×师F₁代、波×文F₁代和波×楚F₁代羊的平均日增重(分别为74.2、72.1和73.5 g)也高于师宗黑山羊、文山黑山羊和楚雄黑山羊的平均日增重（分别为48.7、47.8和46.1 g），差异极显著（P<0.01）；对放牧＋补饲育肥条件下的波×师F₁代、波×文F₁代、波×楚F₁代、师宗黑山羊、文山黑山羊、楚雄黑山羊每组随机抽取6只做屠宰测定，师宗黑山羊、文山黑山羊、楚雄黑山羊的屠宰率、净肉率、眼肌面积等都低于波×师F₁代、波×文F₁代、波×楚F₁代羊，差异显著（P<0.05）。羊肉品味评定综合口感差异不显著（P＞0.05），表明各波杂F₁代羊肉的品质与云岭黑山羊羊肉的品质近似。

Study on Meat Quality and Feedlot Performance of F_1 Which Bore Cross Yunnan Black Goat

With 9 month feedlot of F₁ which were Bore × Shizong (BS), Bore × Wenshan(BW), Bore × Chuxiong (BC) and Shizong, Wenshan black goat under different condition. The results showed that the F₁ average daily gain (ADG) of BS 137.2 g，BW 133.1 g and BC 132.3 g under grazing+additive fed condition, the ADG were higher than S 103.6 g, W 102.3 g and C 101.6 g and signalization diversity (P<0.01). And the F1 ADG of BS 74.2 g，BW 72.1 g and BC 73.5 g were higher than S 48.7 g, W 47.8 g and C 46.1 g and signalization diversity (P<0.01) under grazing condition. There were random selected 6 goats each group for slaughter test of dressing percentage, meat rate and eye meat area, the results showed that the S, W and C goat was lower than F1 of BS, BW and BC and signalization diversity (P<0.05). Meat taste result showed no difference (P>0.05) of all and that indicated that the meat quality were similar between F1 and Yunnan black goat.
