What keeps pig farmers from a massive switch towards boars?

The market – and for pig farmers that is the slaughterhouse- should want to buy and sell pork of non-castrated pigs. In several European countries and beyond, there is still resistance to meat from uncastrated pigs. This is often based on prejudices or stakeholders are not aware of the detection systems that can ensure the proper quality.
Customers then choose traditionally meat from castrated pigs to avoid the perceived risk of boar taint. However, the benefits for pig farmers are large. Boars are financially more attractive than gilts and barrows.
