ABSTRACT:
An apparatus for the semi-automatic feeding of piglets up to 21 days old, comprises an open feeding trough which is supplied with liquid feed in predetermined quantities at predetermined intervals. The inlet to the feed trough is disposed substantially centrally along the length of the trough, in the vicinity of a raised area of the trough, so that the feed distributes itself to the end of the trough under gravity. The strong, dominant animal of the group automatically makes to feed from the trough vicinity of the feed inlet, and the sloping arrangement of the trough ensures that the smaller, weaker animals obtain an adequate supply of feed. The trough surface is smooth and essentially free from crevices, recesses and the like, so that it is essentially cleaned by the feeding piglets themselves.
