Functional morphology and adaptive significance of the mucous membrane of the corners of the mouth in ruminants

Abstract

Using the methods of scanning electron microscopy, morphological and functional features of the mucous membrane of the corners of the mouth in representatives of Bovinae cattle [Bos taurus taurus] with normal and insufficient nutrition and their adaptive significance were revealed. Determination of the morphology of the mucous membrane and its functional structures of the corners of the mouth of ruminants by the specificity of their nutrition and physical condition is shown. Compensatory mechanisms have been identified in the mucous membrane of the corners of the mouth in Bos taurus taurus, caused by poor-quality malnutrition. The ultrastructural features of the architectonics of the mucous membrane and its functional structures of the corners of the mouth and microbiome were revealed in connection with the specific nutritional characteristics of the compared animals. The obtained information can be used in development of the foundations of rational feeding of ruminants, including keeping wild species in captivity and solving the problems of rational nature management and conservation of biodiversity.
