Analysis of short-term rearing characteristic in the captured Yeso sika deer

在日本北海道，野生梅花鹿对农业和林业造成的破坏正在加剧，作为减少损害的对策，短期饲养捕获的梅花鹿进行了有效的利用。本研究旨在阐明捕获的梅花鹿的短期饲养特征。结果表明，成年雌性梅花鹿在分娩或哺乳的影响下体重增长较低。虽然成年公鹿体重增长也较低，但获得的肉重最高。1龄梅花鹿虽然肉重低，饲料利用率高，但增重较高。此外，在成年鹿中，屠宰阶段的育肥效果并不因饲养环境的不同而存在差异。关于生产副产物作为替代饲料的实际应用，提出了降低生产成本的可能性。

In Hokkaido Japan, the agricultural and forestry industries damage caused by a wild Yeso sika deer is intensifying, and effective use by short-term rearing of the captured Yeso sika deer is performed as a countermeasure against damage reduction. The objective in this study was to clarify the short-term rearing characteristic of the captured Yeso sika deer.In the result, adult female deer had low body weight gain by the influence of parturition or breast-feeding. Although the adult male deer was also low body weight gain, the obtained meat weight was the highest. The deer of 1-year-old had high body weight gain, although the meat weight was low, and feed efficiency was high. Moreover, in the adult deer, it was suggested that the difference of the fattening results by a slaughter stage does not come out according to rearing environment. About practical use of the manufacture by-product as a substitute feed, it was suggested that the reduction of a production cost is possible.
