摘　　要：本研究旨在探讨雄麝产麝香能力与繁殖能力的关系,为种质资源选育提供理论基础。实验对224头林麝的麝香产量进行了记录,其中57头具有繁殖力数据。统计分析麝香产量和繁殖力影响因素,以及二者的相关性。结果表明,不同年龄组,不同取香时间组,圈养林麝的产香量差异不显著(P>0.05),但随着年龄增长,产香量有下降的趋势。成体麝的平均产香量显著高于育成麝3.51 g/只(P<0.05)。不同年龄组,雄麝繁殖力差异不显著(P>0.05)。不同取香时间,雄麝繁殖力差异不显著(P>0.05)。相关性研究表明,雄麝繁殖力指标之间相关性显著(P<0.05)。雄麝产香量与双胎率、胎均产子数正相关,随着雄麝产香量的增加,双胎率、胎均产子数也在增加,但相关性不显著(P>0.05)。正确取香不影响雄麝繁殖力。雄麝产香量高,繁殖力指标有相对较好的趋势。结合雄麝体况、年龄、产香量、历年繁殖经历等可以初步筛选配种雄麝。本研究为提高林麝繁殖效率,优化饲养管理提供理论指导。This experiment was designed to explore the relationship between the musk-producing ability and fertility of male musk deer,which would provide a theoretical basis for germplasm resource breeding.The musk production of 224 forest musk deer was recorded,of which 57 had fecundity data.The influencing factors of musk yield and fecundity,and the correlation between them were statistically analyzed.The results showed that there was no significant difference in musk production among different age groups and different musk-extracting time groups in captive forest musk deer(P>0.05),but the musk production tended to decrease with age.The average production of adult musk deer was significantly higher than that of juvenile musk deer,with a difference of 3.51g per deer(P<0.05).There was no significant difference in the fecundity of male musk deer among different age groups(P>0.05).There was no significant difference in the fecundity of male musk deer at different musk-extracting times(P>0.05).The correlation study showed that there was a significant correlation among the fecundity indicators of male musk deer(P<0.05).The musk production of male musk deer was positively correlated with the twin birth rate and the average number of offspring per litter.With the increase in the musk production of male musk deer,the twin birth rate and the average number of offspring per litter also increased,but the correlation was not significant(P>0.05).Correct musk extraction could not affect the fecundity of male musk deer.The higher the musk production of male musk deer,the better the trend of fecundity indicators.Combined with the physical condition,age,musk production,and previous reproductive experience of male musk deer,breeding male musk deer can be preliminarily screened.This study provides theoretical guidance for improving the reproductive efficiency of forest musk deer and optimizing the feeding and management.
