Present day research in swine nutrition with its early weaning programs and its use of the baby pig in biological assays has necessitated the determination of the nutritional requirements of the baby pig. The requirements for two of these nutrients (protein and fat) have not been clearly established. Early studies on the protein and fat requirements of baby pigs were conducted with liquid synthetic milk diets, which were formulated generally on the basis of the composition of sow milk.
