Abstract
    The analysis of the cattle genome, mostly on genetic diversity and population structure, provides useful information for designing effective strategies to improve production, management and conservation of valuable genetic resources, especially of endangered breeds. Bovine DNA analysis involves a series of genetic analysis methods that result in data on the location of genes within the genome, information on certain molecular markers, SNP, etc. At the same time, the application of genomics techniques in the analysis of genetic material in cattle, in order to see the resistance to certain diseases, indicates the importance of the interdisciplinary dialogue between animal health and their genetics. Knowledge of the principles and methods of identifying genetic diversity and evolutionary processes a different species of animals contribute greatly to the implementation of programs for the conservation of valuable genetic resources. This paper presents the most important methods used in the genomic analysis of cattle breeds, starting from DNA extraction, electrophoresis techniques as well as methods used in the analysis of the PCR reaction
