Argentinian device ensures cull cows do not go in calf

Ensuring that cull cows for fattening do not go in calf has been solved by an Argentinian vet.

Enrique Turin, who is also a professor at the National University of Northwestern Buenos Aires, has designed and is producing a bovine intra-uterine device to prevent pregnancy, and some 2.5 million of these have been exported to countries including Brazil and Spain.

He has patented his invention locally and in the EU.
