In order to improve the productivity of house musk shrews, we investigated whether a male could impregnate more than one female within 24 h. Eighteen males and 40 females aged one year were used in this experiment. The mating systems were as follows: one male was paired with one female, one male was paired with two females, and one male was paired with four females. In the fertility rate, six out of 6, 4 of 12 and 4 of 20 females became pregnant and gave birth under three systems, respectively. In the copulatory behavior, numbers of intromissions and ejaculations were more in the 1:1 mating group as compared with the 1:2 and 1:4 groups. We conclude that it is possible for a male to impregnate about one female within 24 h.
