AbstractThe paper aims to review literature data with respect to Romanian native cattle breeds which are considered at risk of extinction. In the last decades, the number of individuals of Romanian indigenous cows decreased significantly, as a consequence of the intensification and specialization of animal productions and agriculture modernization. Some of the native cattle breeds are already lost, due to their crossing with improved breeds. However, after the accession of Romania to the European Union, various preservation programs were initiated, and most of them included biochemical research and studies of molecular or quantitative genetics. All these, associated with the application of reproduction biotechnologies, give a chance to these animals, which are extremely valuable in terms of their genetic resistance to diseases and environmental factors. The reviewed literature on Romanian indigenous endangered cattle breeds confirms that these animals are carriers of a valuable gene pool, which can be kept and bred while applying different reproductive biotechnologies. Consequently, this paper raises awareness on two issues: the decrease of genetic diversity in two Romanian native cow breeds threatened with extinction (Grey Steppe and Romanian Pinzgauer); and the benefits of genetic diversity of the two breeds.
