摘要
目前,我国已有30多年的朱鹮人工繁育历史,人工繁育技术日渐成熟,但依旧存在诸多问题尚未解决。本研究主要对四川朱鹮繁育基地人工繁育工作中的常见问题进行归纳总结,同时基于实践经验以及现有的文献资料对问题产生的原因进行分析,提出相应的解决和预防方案。2017—2019年四川朱鹮繁育基地共繁育朱鹮107只,发现弃卵雄鸟6例、死亡胚胎78例、育雏期疾病8种共94例。经分析,弃卵行为可能是由外界干扰造成,胚胎死亡则可能与亲鸟营养缺乏相关,而育雏期疾病大都由饲喂不当、育雏环境管控不严、雏鸟营养不良所致。因此,加强朱鹮繁殖期和育雏期的管理、改善朱鹮亲鸟和雏鸟的营养水平有助于减少朱鹮人工繁育中问题的发生。
At present,there are more than 30 years of artificial breeding history of crested ibis in China.Although the artificial breeding technology is becoming more and more mature,there are still many unsolved problems.In this paper,the common problems in the artificial breeding of crested ibis in Sichuan Crested ibis Breeding Base were summarized at first.At the same time,the causes of the problems were analyzed based on practical experiences and existing literatures,and the corresponding solutions and prevention measures were put forward.From 2017 to 2019,a total of 107 crested ibis were successfully bred in Sichuan Crested ibis Breeding Base.And there were 6 abandoned male birds,78 dead embryos and 94 cases of 8 diseases in brooding period.Based on careful analysis,it could be known that the behavior of egg abandonment might be caused by external interference,while embryo death might be related to the lack of nutrition of parent birds,and most of the diseases during brooding period were mostly caused by improper feeding,poor control of brood environment and malnutrition of nestlings.Therefore,strengthening the management of breeding period and brooding period and improving the nutrition level of crested ibis parents and nestlings were helpful to reduce the problems in artificial breeding of crested ibis.
