A Manger for Experimental Feeding

Virginia Agricultural Experiment Station, Blacksburg, Virginia

ABSTRACT

Considerable difficulty has been experienced with losses of feed when conducting feeding experiments with dairy animals. When the amount of feed is restricted the head of the animal may be closely confined for a sufficiently long time to allow the animal to eat and by so doing insure against any considerable loss of feed; however, when the animal is fed to the limit of her capacity, eating requires considerable time and she must have enough freedom to insure comfort, therefore losses of feed are difficult to prevent.

The accompanying diagram shows a manger that has proved satisfactory in use under the latter conditions. The mangers were built in sections long enough to provide individual mangers for three stalls. These were built and then set in place before the stalls. Two features distinguish these mangers from those that have been used commonly heretofore. First, a swinging rack or frame is suspended from a horizontal rod thirteen inches from the extreme front of the manger and high enough so that it will swing clear of the floor.
