Abstract: The J Bale Feeder is designed to minimize waste when feeding round bales to a small number of animals and/or to a variety of species, and to eliminate the need for expensive round bale handling equipment at the site where the animals are fed. The feeder consists of a V-shaped round bale cradle on wheels with a roof, a grate below the bale to catch falling hay and a hitch convenient for a regular sized pick-up or even smaller utility vehicle. To further minimize waste, the V-shaped cradle has adjustable openings for the animals to access the bale. A grated, hinged door in the back of the cradle, which opens wide to allow easy loading, combined with a similar grate on the front of the cradle, ensures that animals eat from the adjustable openings rather than the ends of the bale.
