Assessing the Genetic Diversity of Five Cattle Breeds Using SNP Markers Associated with Health

Currently genetic evaluation of animals is an important part of the development of the agricultural complex. The improvement of molecular technologies every year makes it possible to carry out genetic research aimed at finding the most valuable animals in a cheaper and faster way. Indigenous breeds of cattle are an attractive object for such research because they have greater adaptive potential and resistance to diseases. However, modern comparative data on the genetic diversity of most local breeds based on SNP markers associated with health are lacking. Genetic association tests using these genetic markers for the Tagil, Sychev, Suksun and Istoben breeds are still to be carried out. The purpose of this work was to compare the genetic diversity of five cattle breeds using SNP markers associated with the development of ketosis, mastitis and productive longevity.
