Nowadays the processes of crossing of different mammalian species are well characterized in light of genetics, and possibility of reproduction. Generally, lack detailed studies on changes in anatomy and histology of internal systems of hybrids. Bison bonasus hybrid is an interspecific species between the bull of European bison (Bison bonasus), and female of domesticated cattle (Bos taurus). To study the anatomy of tongue and distribution of lingual papillae on Bison bonasus hybrid tongue, a stereomicroscopic and scanning electron microscopic observations was conducted. We aimed to study the appearance of macro‐ and microscopic traits in relation to parental species and other bovids. Results indicate that Bison bonasus hybrid tongue possesses characteristic traits for parental species and ruminants from Bovidae family and also species‐specific features differ from mentioned animals. Specific new traits in hybrid are: V‐shaped arrangement of lingual papillae on ventral surface of the tongue, rosette arrangement of conical papillae on the top of lingual prominence, bigger number of vallate papillae and closer arrangement of vallate papillae. In hybrid observed also the appearance of combination of parental traits. Similar to European bison are rectangular shape of lingual prominence and absence of filiform papillae on the root of tongue. Presence of lateral processes of filiform papillae on the apex of tongue, and arrangement of vallate papillae into two rows corresponded to cattle. Development of new morphological features of tongue and its mucosal papillae in Bison bonasus hybrid opens new issue for future studies on organs of digestive system in animals after hybridization.

Bison bonasus 杂交种（Bos taurus × Bison Bonasus）舌和舌乳头的宏观和微观研究。

如今，根据遗传学和繁殖的可能性，不同哺乳动物物种的杂交过程得到了很好的表征。一般来说，缺乏对杂种内部系统解剖学和组织学变化的详细研究。Bison Bonasus杂种是欧洲野牛公牛 ( Bison Bonasus ) 与家养牛 ( Bos taurus )雌性之间的种间种。为了研究舌的解剖结构和Bison bonasus混合舌上舌乳头的分布，进行了立体显微镜和扫描电子显微镜观察。我们旨在研究与亲本物种和其他牛科动物相关的宏观和微观特征的出现。结果表明野牛奖励杂交舌具有母本物种和牛科反刍动物的特征性状，并且物种特异性特征与上述动物不同。杂交种的具体新性状是：舌腹面舌乳头呈V形排列，舌突顶部圆锥状乳头呈莲座状排列，腭乳头数量较多，腭乳头排列较紧密。在杂种中还观察到亲本性状组合的出现。与欧洲野牛类似，舌突呈矩形，舌根没有丝状乳头。舌尖有丝状乳头侧突，呈两列排列，与牛相对应。舌及其黏膜乳头新形态特征的发展Bison Bonasus杂交为未来对杂交后动物消化系统器官的研究开辟了新的课题。
