摘要
合肥野生动物园自 1 978年开始进行黑麂 (Muntiacuscrinifrons)的饲养和繁殖 ,1 989年第一胎圈养条件下繁殖的黑麂出生 ,到 2 0 0 1年底累计繁殖黑麂 5 1头 ,繁殖种群正处迅速增长期。 1 3年的繁殖资料统计结果表明 ,圈养条件下育龄母麂平均每 1 2个月产一胎 (多数在 1 1～ 1 3个月 ,少数仅 6～ 9个月 ) ,孕期2 4 0d左右 ,哺乳期 2～ 3个月 ,少数母麂可产后发情 ,但极少有两年三次产仔现象。值得注意的是圈养条件下黑麂多在 9～ 1 1月交配 ,4～ 7月产仔 ( 80 39% )。圈养条件下黑麂幼年的死亡率较低 ( 7 84 % ) ,成年黑麂多死于消化道及呼吸道感染等疾病 ( 5 6% )。
Chinese black muntjac(Muntiacus crinifrons) have been kept in the Hefei wild animal park since 1978.The first captive-bred black muntjac was born in 1989 (sire No.87001; dam No.87002), and from 1989 to 2001 51 black muntjac have been born in this institution. Only one young is produced at a time after a gestation period of about 240 days. A new offspring can be produced every 12 months. The lactation period is about 2-3 months. In this captive population, most births occurred between April and July and most matings (80.39%) took place between September and November. However, in wild populations, breeding is continuous throughout the year and there is no definite breeding season. Juvenile mortality has been low (7.84%) in captive animals and the predominant cause of death (56%) in captive adult black muntjacs has been infection of the intestines and lungs.
