Theraw soybeans and heated soybeans were rolled before being• mixed into theconcentrate mixture. Alfalfa hay and concentrate were consumed ad libitum in aratio of 35 % hay and 65 % concentrate.Milk production and percent protein in milk were significantly greater whencows were fed soybean meal or Jet-Sploded beans than when fed raw soybeans.Percent milkfat and total milk solids were not affected by treatment.
