Automatic Stall Feeder
Individual cows are served a measured amount of silage with a first-of-its kind automatic stall or stanchion feeder introduced by Johansen Mfg., Lakeville, Minn.
  A prototype installation has been operating for three years. “We’ve monitored it closely, making a few refinements and ironing out the bugs. We’re now tooled up to produce the feeders commercially,” Loren Johnasen, a mechanical engineer who with his father, Clarence, a DHIA tester in Ottertail County, Minn., teamed up develop the patented silage/haylage feeder.
  The automatic feeder readily adapts to new or existing barns and can be preset to feed from 0 to about 2 bu. of silage per cow per feeding. One cow, for example, can be fed 2 bu. of silage, the cow on her right 1 bu., and the cow on her left can be bypassed completely.
  Silage can be dispensed immediately after the feeder is filled, or, the feeder can be “loaded” and a timer set to drop the feed automatically at a given time during the day or night.
  Johansen is exploring other uses for the feeder. “In feedlots, for example, it could be used to feed all the cattle simultaneously the entire length of the bunk, thus eliminating the usual fighting for position when cattle have to wait to be fed,” he points out.
  It takes about three days to install a complete system for 75 to 100 cows. Measurements are taken and the feeder housing then fabricated to the specs. Cost of a complete system for a stall or stanchion barn is estimated at about $100 per cow, installed.
