鬣羚的行为观察

在人工饲养条件下,采用了目标动物取样法和随机取样法,对鬣羚的冲撞、攻击、领域、择偶、繁殖、母仔等行为进行了观察研究。结果表明,鬣羚初入新环境中,有高度的敏感性,由此产生强烈的应激行为。其中,猛烈地冲击笼舍和不停地向上跳跃是其严重的应激行为之一;有较强的领域行为;在繁殖期间鬣羚对配偶具有选择性;发情高峰期1～2d,怀孕4个月后,腹部明显向两侧膨大,怀孕期220～226 d:仔羚在产后需2h以上才能站立;在15日龄内母羚平均每天要哺乳6～8次;2月龄时,能较好地吃食人工饲料,断奶月龄在2～3个月,断奶时宜将母羚隔至邻笼而将仔羚留在原笼舍。鬣羚笼舍围栏的高度宜在2.5～3m,应为新进的鬣羚提供较暗的小内室,保持安静的环境。

Serow Behavior Observation

We studied behaviors of captive serow （ Capricornis sumatraensis） , including bumping, aggression, reproduction, mating, territorial defense, feeding and lactation. Our methods were focal animal sampling and random sampling. Serow often maintained a high degree of vigilance leading to stress behaviors, of which bumping the cage fiercely and continuously jumping were most frequently observed. Serow showed strongly developed territorial behavior. Serow displayed mate choice behavior during the breeding period. The peak of estrus lasted 1 - 2 days. The belly of female serow showed obvious enlargement to both sides after 4 months of pregnancy and the gestation period ranged from 220 to 226 days. Neonatal serow could stand alone 2 hours after birth. The adult female serow fed 6 -8 times per day for 15 days after birth. Young serow fed on man -made food when 2 months old and were weaned at 2 - 3 months. After weaning, the young serow should remain in the birthing cage and its mother be moved into the adjacent cage. The proper height of a cage for serow is 2. 5 - 3.0 meters and the surroundings should be quiet and dark. Our results provide important information for the further development of captive breeding and protection of serow.
