A process used at a USSR dairy plant for the manufacture of a liquid milk replacer involves blending pasteurized skim-milk with a protein/fat concentrate (made e.g. from 70% buttermilk and 30% bone fat + vitamins and biomycin) to obtain a product with 2% fat. The replacer is stored at <8 deg C in tanks; it is supplied to farms the largest of which is about 17 km from the dairy plant.
