全株玉米青贮饲料在反刍类野生食草动物饲养上的应用

Application of Whole-plant Corn Straw Silage in Feeding of Wild Herbivorous Animals

青贮饲料具有营养丰富、易于储存、占地少、易操作、成本更低、没有火灾问题等优点,随着野生动物养殖的发展,尤其是城市动物园中野生食草动物对于饲草的需求越来越大,青贮应在野生动物饲养中逐渐发挥作用。通过选择人工圈养的野生食草动物进行饲喂全株玉米青贮饲料的试验得出:全株玉米青贮饲料可以作为梅花鹿、马鹿、骆驼、牦牛、大羚羊、羊驼等多种反刍类野生食草动物的饲料;饲喂青贮饲料时需要给动物一个适应期,不同种动物的适应期存在差异;长颈鹿始终拒食青贮玉米饲料。

Silage is rich in nutrition and is easy to prepare and store. With the development of wild animals rearing, there is an increasing demand for forage from the wild herbivorous animals in city zoo. Accordingly, the silage has potential to play an important role in the rearing of wild herbivorous animals. A field experiment on feeding effect of whole-plant corn straw silage on captive wild herbivorous animals was conducted. The results showed that the whole-plant corn straw silage was able to serve as forage for sika deer, wapiti, camel, yak, nylghau, alpacas, and other wild herbivorous animals; an adaptation period was needed when the silage was applied in the feeding of animals, and the adaptation period varied among different varieties of animals; corn silage intake was not observed in giraffe during the experimental period.
