Ananova:

A Belgian vet has produced a cd containing the noise of a grumbling boar to make pigs horny.

The music is meant to make the sows excited in order to insert the sperm more easily by artificial insemination.

According to the Belgian vet Frank Vermeiren the cd has proved already to be a big success in Holland.

"I've already sold 400 of them and the results are terrific," he told Het Laatste Nieuws.

Vermeiren is going to introduce the cd now in Belgium.

"And the harder the music sounds, the more horny they become. A pig farmer I know, has placed sound boxes under the raster in the stable of the sows. It makes the music sound as if an excited boar is living in a stable under their feet. It makes them go wild," he added.
