Horse cloning

Equine cloning over the world

Horse cloning is the process of obtaining a horse with genes identical to that of another horse, using an artificial fertilization technique. Interest in this technique began in the 1980s. The Haflinger foal Prometea, the first living cloned horse, was obtained in 2003 in an Italian laboratory. Over the years, the technique has improved. It is mainly used on high-performance but castrated or infertile animals, for reproductive cloning. These horses are then used as breeding stock. Horse cloning is only mastered by a handful of laboratories worldwide, notably in France, Argentina, North America and China. The technique is limited by the fact that some differences remain between the original and its clone, due to the influence of mitochondrial DNA.
