Genomic testing and its evaluation indicators is one of the well-known scientific branches in the field of biology, genetics, which is actually the science of studying inheritance or transferring traits from one generation to another. Genes carry the necessary instructions to make proteins, which in turn determine the activities of the cell and various actions of the body, thus contributing to the appearance of various traits. Recently, scientists have studied these genetic instructions in the form of a new field of science called genomics. In fact, genomics is a new word that studies all the genes in the body of an organism (genome) and the interaction of these genes with each other and with the surrounding environment. In other words, genomics studies the sequence, structure and function of the genome. The focus of this new scientific branch is on the study and interpretation of genetic information or the genome of an organism. Genomics in livestock With the increase in the population of the earth and the need of people for livestock products, the former methods were not enough to meet this need and new methods were proposed. Today, animal husbandry has entered a new phase that requires new tools and technologies. From 2011 to 2020, using these new methods, America has increased the milk production of dairy animals, especially Holstein, by about 14%. This remarkable progress in milk production has occurred by using animal breeding methods based on genetics along with traditional methods. In traditional methods, the breeder chooses for mating according to the appearance and clinical condition of the animal, which has many errors.

In modern methods, by using genome information and analyzing and checking this information, the genomes of the best animals are determined and then they are selected for mating. Today, with the advancement of genetic science, farmers are able to identify all the effective genes in their livestock, which makes them make decisions with better accuracy.

The process of genetic breeding of livestock is generally as follows:

Preparation of sample containing cow DNA (blood sample – ear tissue – hair)
Genome extraction with laboratory methods
Its analysis by
bioinformatics experts

With this work, it is possible to extract the abilities and weak points hidden in the genome of livestock, and for the development of the next generation, mating of livestock can be done in a controlled and targeted manner.

In the recent year, the Newgen Serve Pars international livestock company (Newgen) consisting of animal science graduates, and leading producers of Iran’s cattle industry, have entered this field by obtaining an official license from the American Veterinary Organization and Iran’s competent authorities. sending ear tissues to American reference laboratories and genetic data analysis have paved the way for genetic modification in the country in order to prevent the exit and removal of animals with high genetic capacity in addition to reducing the costs of livestock farmers and rapid genetic growth
