摘　　要：该试验旨在研究鲁西黑头羊与湖羊在繁殖性能方面的异同,为进一步推广鲁西黑头羊提供科学依据。分别选取50头2周岁鲁西黑头母羊及湖羊母羊,按照品种分为2组,湖羊组为对照组,鲁西黑头羊组为试验组,并在相同的条件下进行饲养。试验结果表明,试验组中鲁西黑头羊的发情率、受胎率、产羔情况均高于对照组湖羊,且试验组初生公羔羊、母羔羊的体重显著高于对照组(P<0.05),而体长无显著差异。综上所述,在相同的饲养管理条件下,鲁西黑头羊的繁殖性能稍优于湖羊,能够在全国范围内进行推广应用。This experiment aims to study the similarities and differences in reproductive performance between Luxi blackhead sheep and Hu sheep,providing scientific basis for further promoting Luxi Blackhead Sheep.In this experiment,502-year-old Luxi blackhead ewes and Hu sheep ewes were selected and divided into two groups according to their breeds.The Hu sheep group was the control group,while the Luxi blackhead sheep group was the experimental group.They were raised under the same conditions.The experimental results showed that the estrus rate,conception rate,and lambing status of Luxi blackhead sheep in the experimental group were higher than those of Hu sheep in the control group,and the weight of newborn male and female lambs in the experimental group was significantly higher than that in the control group(P<0.05),while there was no significant difference in body length.In summary,under the same feeding and management conditions,the reproductive performance of Luxi blackhead sheep is slightly better than that of Hu sheep,and can be promoted and applied nationwide.
