半自然条件下麋鹿的生长发育与繁殖习性

在大丰保护区的半自然条件下，麋鹿新产仔鹿性二型差异大于圈养条件下的仔鹿；１龄幼鹿第１年生长发育迅速，其后足长已基本达成体后足长；４岁时后足长即已显著大于引进的成体鹿。大丰雌性麋鹿３岁开始产仔，比圈养条件下晚１年，４岁时体重方达成体重。雄性５岁后方能达成体重并才有机会获得交配权．发情期主要集中于６月上、中旬，产仔期主要集中于３月中、下旬，产仔半数时间为３月２７日，产仔期比圈养麋鹿更趋集中。仔鹿产后１～３天为“印记”的敏感期，１周龄后即开始随群活动并有觅食行为。

THE GROWTH AND BREEDING HABIT OF MILU(ELAPHURUS DAVIDIANUS) IN DAFENG RESERVE

In semi-natural condition of Dafeng Reserve, the difference of weight of neonatal males and females was 2.24 times that in captivity. The hind foot length of 4 years old was significantly more than that of introduced deer(>5 years old). Females conceived in the third year in which the body weight was about 89% of an adult, and males began to have the opportunity to copulate in the fifth year. The rutting season concentrated in the first half of June, and the gestation length was 287 days. 71. 2% of the births occurred between March 16 and April 4 with the median birth date on March 27. The results discussed the biologicAl characteristics of wild Milu and the genetic diversity conservation.
