波尔山羊与山西本地山羊杂交改良效果研究

波尔山羊是世界著名的优秀肉用山羊品种,有“肉羊之父”的美称,具有体格高大、后躯发达、生长发育快、肉质性能好、屠宰率高、繁殖无季节性、适应性强、杂交改良各地山羊增重效果显著等特点。通过对波尔山羊×洪洞奶山羊(波奶)、波尔山羊×安哥拉山羊(波安)、波尔山羊×黎城大青羊(波青)3个杂交组合羔羊与纯种黎城大青羊作对比,各杂交组合在生长特性、育肥特性、屠宰性能及羊肉品质方面,都表现出良好的性能。特别是黎城大青羊,作为山西省的优良地方山羊品种,其良好的适应性和产肉性能表现突出,波青杂交羔羊也表现突出;奶山羊作为杂交母本,有良好的体形和泌乳性能,所产羔羊不论在产羔率还是羔羊生长速度上比其他品种有明显提高,但在肉质上需进一步改善。
