osg::Box is the thing you are after. Create a ShapeDrawable for one, and add it to a group that is part of, or that contains your cow model.
Then set node flags or a cull callback to make the ShapeDrawable invisible, and if you like, you could also set flags on the intersection visitor to only attempt to make intersections with your new collision boxes.
