The Ad-lib feeder is the ideal feeder for ad-lib feeding, and is suitable for groups of 10 to 12 sows. In the case of larger groups, several feeders can be used. The feeder can be adjusted very precisely to ensure that the sows do not overeat and it forces them to eat slowly. This perfect adjustment of the Ad-Lib feeder is also very well suited for daily rationing. The elevated trough provides an easy fodder position for the sows, and it is kept very clean by the elaborated low point. As a result no fodder residue remains. The feeder is available with or without water supply. In combination with the DRN 4 stainless steel drinking trough, this feeder forms the ideal solution for the ad-lib feeding of groups of sows.
