Liquid whey was fed to dairy cows and heifers to determine its nutritive value. Sixteen cows were allotted to groups of four each and randomly assigned to a treatment (1) water only, (2) whey plus 30.2 liters of water daily, (3) whey plus 15.1 liters of water daily, and (4) whey only. Grain was offered at 7.5 kg per animal daily, and hay was free choice. Hay consumption was reduced by feeding whey, but milk production and composition were not changed. Total consumption of liquid (water whey) was the same for the four groups.
