  • Patent number: 5437244
    Abstract: The livestock watering tank includes a top, bottom and sidewall. The top wall has an opening for access to the water. The opening is closed by a float. The animal drinks by pushing the float down into the water with its mouth, causing the float to partially submerge so that water is exposed and may be drunk. The float rises back to its natural position after the animal finishes drinking. The float has a port for allowing water or other weighted substance to be introduced into it. The addition of the substance into the float generally neutralizes the buoyancy of the float with respect to the water in the tank, thereby decreasing the amount of force necessary for the animal to submerge the float for drinking.

  • Patent number: 4337728
    Abstract: A method of feeding hogs is disclosed. The method includes the steps of providing all the hogs with all the feed they care to consume for a limited feeding period of time, and thereafter denying all feed to all the hogs for a limited feedless period of time. Preferably, weaner hogs are provided with all the feed they care to consume during three separated, limited feeding periods of approximately two hours each per day. These feeding periods are alternated with three feedless periods during which all feed is denied to all the small hogs. This feeding regime is maintained until the hogs weigh approximately 100 pounds. Thereafter, two limited feeding periods are provided each day until the hogs reach market weight. In this way, hog weight gain per day is maximized and the amount of feed consumed per pound of hog weight gained is minimized.Apparatus for carrying out this feeding method is also disclosed.

  • Patent number: 4165683
    Abstract: A barbecue apparatus intended primarily for outdoor use, in which two side panels and two end panels form a generally rectangular shaped body with an open top and bottom, and a rotatable grill is supported by the upper edge of the two end members in the upper part of said body consisting of two sections for holding meat therebetween. A basket or other elongated retainer is disposed in the bottom of the body for holding burning fuel for cooking the meat, and a lid, preferably hinged to the upper edge of one of the side panels of the body, closes the body while the meat is cooking to provide effective radiation of heat onto the meat and to direct the hot gases on and around the meat. The body and lid are preferably constructed of stainless steel which provides a reflective inner surface for directing the heat from the burning fuel onto the meat while the lid is in its closed position.

  • Patent number: 4121538
    Abstract: A farrowing crate is provided which has adjustable connecting structure for connecting the side walls thereof to the end walls thereof in various adjusted positions with the farrowing crate width at the top remaining constant and the width at the bottom being increased step-by-step as the side wall is raised. The side walls are constructed of tubular construction with a lower horizontal tube having pins welded thereto which are selectively engagable in apertures arranged at respective steps of stepped brackets attached to the end walls. The stepped brackets exhibit inwardly facing vertical step surfaces which restrain lateral outward movement of the side wall during the adjustment process. The upper tubular member of the side wall includes locking apertures. Upper brackets are attached to the upper parts of the end walls, which upper brackets form stepwise nesting places for the upper tubular member as well as apertures alignable with the locking apertures to accommodate latch pins.
