摘　　要：为探究非遗传因素对济宁青山羊繁殖性状的影响,本研究收集山东省嘉祥济宁青山羊原种场和曹县正道牧业科技有限公司2012—2023年母羊产羔记录共2912条数据,使用最小二乘分析和多重比较分析场、胎次、产羔年份、产羔季节和产羔类型对繁殖性状的影响。结果表明,不同胎次、产羔年份和产羔类型对母羊的繁殖性能具有极显著影响,其中母羊在第4次及以上胎次的胎产羔数和胎羔羊总产羔重最高,且母羊的总产胎次越多,总产羔数和总产羔重越高;场对羔羊平均初生重具有显著影响,对其他性状具有极显著影响;产羔季节对胎羔羊平均初生重具有显著影响,对胎产羔数和胎羔羊总产羔重影响不显著,其中夏季产羔的胎羔羊初生重较高。本研究结果可为今后济宁青山羊遗传参数估计和遗传评定奠定基础,以便制定更准确的育种方案。In order to explore the effects of non-genetic factors on reproductive traits of Jining Grey goats,a total of 2912 pieces of data of ewe lambing records from 2012 to 2023 were collected from Jining Grey Goat Breeding Farm in Jiaxiang and Zhengdao Animal Husbandry Technology Co.,Ltd.in Caoxian in Shandong Province,and least squares analysis and multiple comparison analysis were used to analyze the effects of field,parity,year of lambing,season of lambing and type of lambing on reproductive traits.The results showed that different parities,lambing years and lambing types had extremely significant effects on reproductive performance of ewes.Among them,lambing number and total lambing weight of ewes per parity in the fourth and above parities were the highest,and the more the total parity of ewes was,the higher the total lambing number and lambing weight were;field had a significant effect on average birth weight of lambs,and had very significant effects on other traits;lambing season had a significant effect on the average birth weight of lambs,but had no significant effect on lambing number and total lambing weight of ewes per parity,and the birth weight of lambs in summer was higher.In summary,the results of this study could lay the foundation for genetic parameter estimation and genetic evaluation of Jining Grey goats in the future,so as to formulate more accurate breeding programs.
