In lamb feeding trials here at Iowa Station during the past winter, we had two main objectives in mind: (1) To find whether it would pay to feed lambs corn silage and 'alfalfa hay instead of hay and (2) whether one can and should push lambs up to a good feed of shelled corn and hold them at that level, or whether the amount of corn should be shifted from time to time in accordance with the appetite of the lambs to keep them on full feed.
