Research conducted at South Dakota in 1955-56 has shown that 10 to 19 per cent of ground alfalfa hay in a protein supplement will decrease the consumption of the supplement (S. Dak. Farm and Home Research, Feb. 1957). This resulted in a lowering of the feed cost per unit of pig gain. The objectives of this experiment were to compare three levels (10, 20 and 30 per cent) of ground alfalfa hay in a protein supplement and to compare these supplements fed free-choice to a complete mixed ration.
