They plan to perform myostatin inhibition to boost the muscles in horses.
They will develop horses with more muscle mass, which could run faster for longer distances and jump higher. At the end of 2017, Kheiron-Biotech announced that they have healthy embryos created by this type of gene editing that the horses will be born by 2019.
In 2016, six cloned polo ponies won the Argentinian Open with polo star Adolfo Cambiaso on board. The first horse was cloned in 2003, with the other main laboratory in the business of bettering breeding being Crestview Genetics, based in Texas.
When it comes to clones, the International Federation for Equestrian Sports (FEI) lifted a ban in 2013.
This result is related to a prediction that I made in 2006. I predicted that gene doping would rampant in horse and dog racing. However, I expected this back in 2008. Gene editing has been possible for quite a while. There could have been gene doping that was not detected. The Kheiron-Biotech work is a very public development of super horses.
