Armidale’s Chiswick research station have been successful in making surrogate rams and bulls by stem cell. The research has been described by experts as more significant than artificial insemination or cloning for Australia’s livestock industries.
The experimental approach proven so far in sheep involves irradiating a ram’s testes while placing stem cells from a second ram into the testes of the first, ram A.
In the following weeks ram A produces semen the usual way, but is using the stem cells of ram B and therefore producing semen carrying the genetics of ram B rather than that of his own.However, research is still in the experimental phase with results yet to be formally published.
