Title: BOAR CART FOR INSEMINATION OF SOWS
Abstract:
A boar cart (10) for carrying a boar through alleyways of a sow insemination area for interaction with the sows during insemination is formed by a cage for containing the boar including a cage floor (17) on which the boar stands, two sides (50, 51) each defined by vertical bars on a respective side of a longitudinal center line of the cage assembly for confining the boar so that the boar is maintained extending longitudinally of the cage, a front (52) and a rear (53) defined by vertical bars, at least one of which can be opened as a door to allow entry and exit. The cage is mounted on rear driving wheels (22) and front steering/caster wheels (35, 36). The cage is defined by a front portion (12) and a rear portion (11) connected together for pivotal articulated movement about one or two pivot couplings defining a vertical pivot axis (13) arranged substantially at the center line such that the cage can articulate to the left and to the right for navigating left and right corners in the alleyways while the boar is retained in the cage. The length of the cage is reduced by bowing the front and rear bars. The front steering wheels (35, 36) can be set to direct the steering slightly to the left or right so as to tend to guide the cage along one or other side of the alley where it has rollers (43, 44) to run along a rail and hold the boar close to the sows on one side.
