Editing the genome of farm animals using CRISPR / Cas9 technology

One of the most discussed topics in modern genetics is the technology emergence for editing of biological objects genomes CRISPR / Cas9, which has a huge impact on molecular biology, this technology allows adding, removing and making changes to the genome of various organisms, including higher mammals. It is an innovative and powerful tool for obtaining animals with specified characteristics. It has become possible in a relatively short time to create an animal with the modified genome, which improves the quality and efficiency of livestock production.

Influence of the polymorphism complex of κ-casein (CSN3) and prolactin (PRL) genes on the milk productivity of the holstein first calf heifers

The presented study is dedicated to the influence of the polymorphism complex of κ-casein (CSN3) and prolactin (PRL) genes, which are responsible for milk quality and milk productivity. The study was carried out among Holstein first calf heifers by Integrated Agricultural Production Centre “Breeding farm named after Lenin” of Atninsky district of the Republic of Tatarstan. DNA samples were separated from blood samples of 261 cows for identification and genotyping according to kappa-casein and prolactin genes by PCR-RFLP analysis method.
