Abstract

Charon ventriculi comprised over 30% of the total protozoa observed in rumen contents of a Flamenga cow fed Rhodes grass hay (Chloris gayana). Both percentage of composition and concentration decreased markedly when concentrate was added to the ration or the animal was fed in pasture. Although C. ventriculi is classified as a holotrich, concentrations of this species in the rumen appear to follow a diurnal cycle more closely related to be entodiniomorph protozoa.

摘要

瘤胃袋形虫在以罗德草干草（Chloris gayana）为食的弗拉门戈奶牛瘤胃内容物中观察到的原生动物总数中占比超过30%。当在日粮中添加精饲料或动物在牧场饲养时，其组成百分比和浓度均显著下降。尽管瘤胃袋形虫被归类为全毛目，但该物种在瘤胃中的浓度似乎遵循与内毛目原生动物更密切相关的昼夜循环。
