自从他们发现,据报道,来自不同地理位置的家畜的瘤胃纤毛虫。然而,到目前为止,只有一个与巴西牛相关的纤毛虫分类学清单。本研究旨在评估社区组成,相对丰度,丰富,巴西牛瘤胃纤毛虫的密度,其饲喂饮食中补充了新月尿素水平。在所有分析的治疗方法中,一个子类,两个命令,三个家庭,11属,并鉴定出31种纤毛虫。在使用的四种处理中,纤毛虫群落组成和物种丰富度有所不同。然而,总纤毛虫密度不受实验饮食的影响。我们描述了一种新的Enodiniid形态类型,奥伯纳核菌,并在巴西第二次录制了Oligoisotrichabubali。
Since their discovery, rumen ciliates of domestic cattle have been reported from various geographic locations. However, until now there is only one taxonomic inventory of ciliates associated with Brazilian cattle. The present study aimed to assess the community composition, relative abundance, richness, and density of rumen ciliates in Brazilian cattle, whose feeding diets were supplemented with crescent urea levels. Across all treatments analyzed, one subclass, two orders, three families, 11 genera, and 31 species of ciliates were identified. The ciliate community composition and species richness varied among the four treatments used. However, the total ciliate density was not affected by the experimental diets. We described a new entodiniid morphotype, Entodinium caudatum m. orbonuclearis, and recorded Oligoisotricha bubali for the second time in Brazil.
