| 概要 | The carnivorous animal eats a processed mainly muscle piece at the zoo, whereas the animals pushes skin and bone aside and gets muscle in nature. Recently, “carcass feeding”, which is an approach feed...ing a zoo’s carnivorous animal a large carcass, is getting attention as environmental enrichment in Europe and America. However, it is hard to obtain the large carcass in Japan, and hence the carcass feedings are not performed. On the other hand, deer and wild boar are captured to reduce negative impact on agriculture and forest vegetation in the various parts of Japan. However, the use of captured deer and wild boar is limited. Therefore, we connected stakeholder concerned with “the problem of the animal welfare in zoo” and “the issue of local beast harm” using technique of the scientific communication, and have begun to grope for solution to the problem as the joint project from the summer in 2017. We are active currently as “Wild meǽt Zoo”. In the results of feeding of carcass and behavior, extension of feeding time and diversification and a change of feeding pattern were observed. The results suggest that carcass feeding is effective as enrichment for zoo’s carnivorous animal. The difference of sterilization did not affect feeding behavior. In our experiment, we fed the carcasses whose head, internal organs, and blood were removed. This process may reduce the psychological burden (loathsomeness etc.) on park visitors.続きを見る |
