Abstract

Feed hopper for a sow has opening at bottom surrounded by a seat upon which a ball check is adapted to rest, thereby to seal the opening and prevent the discharge of feed therethrough. A sow can nudge upwardly the ball check, unsealing the opening and permitting the discharge of feed from the hopper. Vertically adjustable means limit upward movement of the ball check so as to limit the maximum extent to which the opening can be unsealed. A water button, operatively connected to a source of water, can be nudged by the sow to discharge water for her.
