Researchers from the Faculty of Agronomy of the University of Buenos Aires are working on a new technique that would allow them to change the sex chromosomes of an animal to get the desired sex in a cloned animal.
They are specifically interested in creating bulls from cows’ chromosomes to increase production.
“This would increase the number of calves that can be produced, because while a cow with expensive hormone treatments can generate only 20 or 30 calves per year, a bull produces more than 10,000,” said Daniel Salamone, director of the university’s Laboratory of Animal Biotechnology.
“In the long term, we are looking to develop a method to change the chromosomes of a female. Instead of having the original XX, we would have XY,” specified Salamone.
The same laboratory also worked in creating the first cloned transgenic cows of South America, which are able to generate growth hormones in their milk.
And they have also cloned the first horses of the region.
