Automatic feeder to reduce stress at weaning. A smooth transition continuing the piglet's positive growth curve from the first day of weaning. Need not to be fixed to the floor of the box. With a sensor to distribute and mix the feed. This feeder encourages increased feed intake and fast growth, resulting in fewer days to finish. It mixes feed with water in the trough, while a control panel allows little and often feeding at preset times to mimic the sow’s own feeding pattern. A warm water version of the Transition Feeder is available for young piglets when feeding milk replacer.
