摘要：

摘 要：【研究目的】进一步探究适合神木县区推广的肉羊最佳杂交组合和生产模式；【方法】在相同舍饲条件下的陶细、德细、萨陶细、特陶细、萨德细、特德细6个杂交组合中各随机选择同期出生的羔羊30只，进行了为期四个月的对比饲养试验。【结果】结果表明，三元杂交组合羔羊在日增重和精料报酬均极显著地高于二元杂交组合（p<0.01），其中以萨陶细组的日增重最高。特陶细组的屠宰率和净肉率虽然相对较高，但与陶细组以及其它三元杂交组没有明显差异（p>0.05）。【结论】由此可见，三元杂交效果较好，萨福克作杂交肉羊的终端父系更具优势。

Abstract : 【OBJECTIVE】In order to find the best cross combination of sheep and Production System of lamb for Shenmu county，【METHOD】300 lamb from 6 Cross Combination, including Poll dorset♂×Fine wool sheep ♀(PF), German mutton merino♂ ×Fine wool sheep ♀(GS), Suffolk♂× Poll dorset♂×Fine wool sheep ♀(SPF), Texel♂×Poll dorset♂×Fine wool sheep ♀(TPF), Suffolk♂×German mutton merino♂×Fne wool sheep ♀(SGF)and Texel♂×German mutton merino♂×Fine wool sheep ♀(TGF), were compared on fattening effect. All of age-group lambs were kept in same indoor feeding condition. 【RESULTS】The results showed that the daily gain, feed conversion efficiency of three-way crosses were higher significantly than that of two-way crosses（p<0.01. The daily gain of SPF was the highest. The dressing percentage and net mutton rate of TPF were the highest, but there was no significant difference between PF, SPF, SGF, TGF and this combination. 【CONCLUSION】Thus, the effects of three-way crosses were better and Suffolk was of more superiority as terminal paternal of crossbred sheep.
