The invention concerns an apparatus to teach cows to lie down in the cubicles which are to be found for that purpose in the stable instead of lying down on the wet dirty floor of the passageway. The apparatus according to the invention is fastened on the cow with a girth and measures the electric resistance of the floor on which the cow is going to lie down. If the animal is going to lie down on a floor with a low electric resistance the apparatus produces some sound signals, if the animal does not react by standing up this is followed by an electric shock. |
