摘要： This invention relates to a stand for supporting hay bales above the ground. The inventive hay stand The device is formed in the shape of an rectangular prism or cuboid from an inert plastic, closed-cell, polyurethane structural foam that will not allow water or air to move through it. The devices are constructed by pouring the structural foam material into forms that are constructed to yield the desired shape. The structural foam has two chemicals that are mixed and then poured into the form. The foam then heats and rises to take on the shape of the interior of the form. Once the foam is fully cured, the forms are removed, and the device is ready for use. Hay stands constructed in accordance with the present invention are useful for protecting hay bales from spoilage due to ground moisture.

摘要： This invention relates to a feeder for feeding hay bales to animals. The inventive animal feeder includes a feeder base, a feeder cone and a tray. The feeder cone is mounted above the base for receiving and holding the hay to be fed to animals. In one embodiment, the feeder cone has three inwardly sloping cone side assemblies and an inwardly sloping shortened cone side assembly to facilitate loading hay into the feeder cone. A tray is supported by the base and positioned below the feeder cone to catch hay that falls as animals are feeding from the feeder cone, preventing waste and exposure to parasite and other contaminants. In an alternative embodiment, all four sides of the feeder cone 12 are constructed the same, with no shortened side.
