Rumen contents from four blue wildebeest (Connochaetes taurinus) and six black wildebeest (Connochaetes gnou) were collected from two locations during two winter culling seasons. A total of 16 species of protozoa were found in blue wildebeest with Dasytricha ruminantium, Opisthotrichum janus and Ostracodinium gracile occurring in all four animals. In black wildebeest, 23 species of protozoa were observed with only Diplodinium bubalidis (caudal spine morphotype) and Ostracodinium damaliscus being present in all animals. In the blue wildebeest, the total number of species in an individual animal varied from 9 to 11 and in the black wildebeest, the number ranged from 4 to 14. Concentrations of cells per ml ranged from 1110 to 5880 in the blue wildebeest and 3120 to 6240 in the black wildebeest. This study is the first report on protozoa species in the blue and black wildebeest. A new species of Entodinium is described, Entodinium taurinus n. sp., observed in the rumen contents of three blue wildebeest. Several physical parameters of the digestive tract were also measured, including distribution, pH and density of gastrointestinal contents in different sections of the total tract. In vitro gas production was estimated for rumen, cecum and colon contents.
从两个冬季淘汰季节的两个地点采集了来自 4 只蓝角马（Connochaetes taurinus）和 6 只黑角马（Connochaetes gnou）的瘤胃液。在蓝角马中发现了 16 种原生动物，其中 Dasytricha ruminantium、Opisthotrichum janus 和 Ostracodinium gracile 存在于所有 4 只动物中。在黑角马中，观察到 23 种原生动物，只有 Diplodinium bubalidis（尾刺形态型）和 Ostracodinium damaliscus 存在于所有动物中。在蓝角马中，个体动物的物种总数从 9 种到 11 种不等，而在黑角马中，数量从 4 种到 14 种不等。每毫升细胞数在蓝角马中从 1110 到 5880 不等，在黑角马中从 3120 到 6240 不等。本研究是首次报道蓝角马和黑角马的原生动物种类。描述了一种新的内变形虫属物种，即 Entodinium taurinus n. sp.，在 3 只蓝角马的瘤胃液中观察到。还测量了几个消化道的物理参数，包括总消化道不同部位的分布、pH 值和胃肠道内容物的密度。估计了瘤胃、盲肠和结肠内容物的体外产气量。
