  • System and method for uniformly delivering feed rations to the feedbunks of animal pens in a feedlot
    Patent number: 5878402
    Abstract: A system and method for uniformly delivering assigned feed rations to the feedbunks associated with animal pens. The system includes a feed delivery vehicle having a feed storage compartment and a scale. The function of the scale is to weigh the amount of feed in the storage compartment at sampled time intervals, and produce a first data signal indicative of the weight of the feed at these sampled time intervals. The vehicle also has a ground speed radar unit which measures the true ground speed of the vehicle at sampled time intervals as the vehicle travels alongside of the feedbunk, and produces a second data signal indicative of the vehicular speed at these sampled time intervals. A computer aboard the vehicle processes the first and second data signals along with information regarding the length of the feedbunk and produces a control signal as the vehicle travels alongside the feedbunk.
