An Appropriate Genetic Approach to Endangered Podolian Grey Cattle in the Context of Preserving Biodiversity and Sustainable Conservation of Genetic Resources

Abstract

In the context of the general phenomenon of diminishing genetic diversity, especially in cattle, the conservation of endangered species plays a primary role. The disappearance of some animal populations can irreparably affect the biodiversity of genetic resources. Among the most ancient European cattle are breeds that belong to the Podolian group, the history of which is still not well established. The common origin of these breeds is the wild ox (Bos taurus primigenius), which has been declared extinct since the 17th century. The purpose of this paper is to highlight and compare the latest studies on the origin, evolution, genetic diversity, and phylogenetic relationships of Podolian cattle, with special emphasis on the endangered Romanian Grey Steppe. The importance of studying these cattle derives from the special biological properties by which they have distinguished themselves over time (adaptability and resistance to diseases, severe climate and habitat conditions, hardiness, and longevity). The bibliographic references reviewed in this study confirm that these breeds are carriers of valuable genes that must be preserved for improvement of other cattle and protection of biodiversity. The information presented represents a valuable tool for efforts to conserve endangered cattle.
