摘要
2002年天津动物园东方白鹳人工孵化与育雏及自然孵化与育雏均同时获得成功。通过对笼养东方白鹳自然育雏与人工育雏过程中的孵化、育雏等行为的观察和比较分析,得出以下结论:从1日龄到70日龄,人工育雏与自然育雏在东方白鹳雏鸟生长发育方面的差异较小;自然育雏与人工育雏日饲喂量都增多,但日饲喂次数及饲喂间隔正好相反'行为表现方面自然育雏的东方白鹳比人工育雏的东方白鹳更早学会啄食、扇动翅膀、站立和行走。
In 2002,natural and artificial hatching and brooding of Oriental white stork were both successful in Tianjin Zoo.We comparing natural hatching and brooding with artificial hatching and brooding.We defined natural hatching and brooding as an adult pair of storks nesting in captivity and rearing young without human assistance.Artificial hatching was carried out in incubator and chicks were hand - fed by zoo personnel.During the first 70 days of life,artificially brooded nestlings showed no significant difference to naturally brooded nestlings in terms of growth rate.Food intake of naturally and artificially brooded nestlings increased but the feeding time and feeding interval decreased for naturally brooded nestlings.Naturally brooded nestlings learned behaviors such as pecking,vibrating wings,standing and walking at earlier ages than did human - reared nestlings.
