摘要
仔狐早期（５日龄内）的死亡率最高，占哺乳期死亡数的４７％；占仔狐、育成狐死亡总数的４１％。本研究对北极狐初产雌狐实行短期环境监控，同时进行恢复或强化母性的调驯，连续５年产仔雌狐的母性行为正常，有效地扼制了仔狐的早期死亡，５日龄内仔狐的成活率平均达９８６８％，比对照组高２１６５％。
Early mortalty of larva fox is the highest,and the proportion of it to mortality number in nursing period is 47%,the proportion of it to the mortality number of larva and adult foxes is 41%.Short period monitoring environment was practised on primparous Aratic fox.Trainning materal instinct was restored and strengthened.It indicated that materal instictive action of farrowing vixen was nomal for 5 years,early mortality of larva fox was controlled effectively.Within 5 days,the average survival rate of larva fox is 96.68%,it was higher than control groups by 21.65%.
