8-280+ lb (3.5-130+ kg) pig weight

Our extended hopper dry finishing feeder offers up to 80% more feed capacity than the standard height version and can be used in both grow-to-finish and wean-to-finish facilities. This feeder’s wide feeder spaces provide ample shoulder room for the largest market weight pigs while its low-lip trough allows it to be used for pigs as small as 8 lb (3,5 kg). Its divider allows free feed flow between spaces and its deep feeder headspace reduces feed waste.
