The use of lard as the sole source of fat was investigated in a formula fed to healthy premature infants. It was absorbed as well as a conventional cow's milk fat/vegetable oil mixture in a control formula (which was otherwise identical), and is supported normal growth. Lard is cheaper than cow's milk fat and appears to be a satisfactory substitute as an energy source.
