  • Patent number: 4998506
    Abstract: In general, cages for young pigs or other animals are either unsanitary or do not provide protection from the elements, i.e. a warm dry and draft free environment. A simple solution to these problems is provided by a unitary two-piece housing with a generally rectangular base, a feed trough on the top front end of the base, a removable perforate floor which is easy to wash, a liquid waste storage and a controlled discharge drain outlet, a cover mounted on the base with an open front end, and a skeletal rod or wire gate for closing the open front end slidably and pivotally mounted in the cover for movement between a closed position in the open front end and an open position permitting easy access to the animals. The gate prevents soiling of the feed trough by the animals in the housing, and the stall configuration reduces competition at feeding times. The feed trough is further designed to distribute liquid feed equally along the length of the housing.
