摘　　要：利用鲁西黑头羊新品种选育技术资料,对其繁殖性能进行研究分析并与其父本和母本的繁殖性能进行了比较。结果表明:鲁西黑头羊公羊初配年龄为10月龄,实配日龄345 d,公羊平均射精量为(1. 27±0. 39) m L;母羊发情周期平均18. 72 d,妊娠期平均147. 01 d;母羊全年可发情配种,繁殖产羔,两年3产,遵循"春配秋产、秋配春产"的规律;初产母羊平均产羔率162. 07%,2～5岁经产母羊平均产羔率为222. 26%;公羔初生重平均(3. 99±0. 99)kg,母羔平均(3. 71±0. 95)kg。表明鲁西黑头羊繁殖性能优于其父本品种黑头杜泊羊,具有常年发情,多胎、多羔的优良特性。Using the breeding technical data,the reproductive performance of Luxi Blackhead Sheep were analyzed and compared with its male and female parents.The results revealed that the first mating age of Luxi Blackhead Sheep rams was10-month old,the real mating age was 345-day old,and the average ejaculation amount of rams was(1.27±0.39)mL.The average estrus cycle of ewes was 18.72 days and the averages pregnancy cycle was 147.01 days.Ewes could be oestrus and breeding lambs all the year round with three births in2years following the law of“spring mating then autumn lambing,and autumn mating then spring lambing”.The average lambing rate of primiparous ewes was 162.07% and the multiparity ewes of 2~5years old was 222.26%.The birth weight of ram and ewe lambs were(3.99±0.99)kg and(3.71±0.95)kg,respectively.In summary,the reproductive performances of Luxi Blackhead Sheep were better than its male parent Blackhead Dorper Sheep and had excellent characteristics such as non-seasonal estrus,multiple births and prolificacy.
