In Brazil, refused to select “artificial” cows – This project was launched by an American company this spring. Recombinetics
Scientists in the process found that in the edited genome Holstein cows crept in error. This is due to a special bacterium, incredibly resistant to all known antibiotics. More to come figure out how the harmful microorganism ended up in the gene material, but biologists hope this didn’t happen in the walls laboratories, but on a pasture where full sterility is maintained impossible.
The project is suspended, but it remains a priority for breeders. It’s about creating a hornless milk herds on the basis of the highly productive Holstein breed, and not less promising Hereford or Aberdeen Angus – these breeds are hornless from birth.
