Abstract

Abstract:

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.

Key words: forest musk deer (Moschus berezovskii), musk production, twin birth rate, average number of offspring per litter, non-pregnant rate, musk-producing ability, fertility
