作者于1987～1991年对伊犁鼠兔繁殖生物学进行了初步研究。结果显示,伊犁鼠兔具有年繁殖两胎的时间和可能,第1胎约产于6月初,第2胎约在7月底或8月初。由于其种群密度低,栖息环境恶劣,有些雌体可能失去交尾机会。在捕获的4只雌性成体中,仅1只参加过当年的繁殖,也许部分雌体每年仅产1胎。在所见的21只鼠兔中,雌雄性比为1∶0.8,未成年体鼠兔仅占28.57%。 The author conducted a preliminary study on reproductive biology of Yili rabbit from 1987 to 1991. The results show that the Iraqi poult rabbits have two years of reproductive time and possible, the first child was about early June, the second child about the end of July or early August. Due to their low population density and poor habitat, some females may lose the chance of mating. Of the four female adults captured, only one participates in the current year’s breeding, and some of the females may only produce one child per year. Among the 21 hamsters seen, the ratio of male to female was 1: 0.8, while that of juvenile rats was only 28.57%.
