| 摘 要： | 对5个杂交组合羔羊的生产性能进行了测定。结果表明:羔羊哺乳期平均日增重2个三元杂交组合高于3个二元杂交组合;断奶育肥期日增重德克塞尔×无角道赛特×小尾寒羊(TL×PD×XW)和萨福克×无角道赛特×小尾寒羊显著高于无角道赛特×小尾寒羊(PD×XW)和德克塞尔×小尾寒羊(TL×XW)(P<0.05);料重比TL×PD×XW和SK×PD×XW极显著高于PD×XW和TL×XW(P<0.01),显著高于SK×XW(P<0.05);胴体重、屠宰率、眼肌面积、胴体净肉重等指标2个三元杂交组合显著或极显著高于3个二元杂交组合。建议在半干旱地区开展肉羊经济杂交时,以SK×PD×XW组合最好。

| Abstract: | Lamb growth performance from 5 cross combination was measured.The results showed that average weight gain during lactation period of 2 three-way crossbreeding combinations was higher than 3 two-way crossbreeding combinations.During fattening period,Texel×poll Dorset×Small-tail han(TL×PD×XW)and suffolk×poll Dorset×Small-tail sheep were significantly higher than poll Dorset×Small-tail han(PD×XW)and Texel×Small-tail han(TL×XW)(P<0.05).Feed gain ratio of TL×PD×XW and SK×PD×XW was significantly higher than those of PD×XW and TL×XW(P<0.01),significantly higher than SK×XW(P<0.05).The indicators of carcass weight,dressing percentage,loin eye area,carcass meat weight of lambs of 2 three-way cross combinations were higher than 3 two-way cross combinations.Therefore,SK×PD×XW is optimum crossing combination in Semi-arid areas. |
