Abstract
RAT milk contains a large amount of fat and protein1. The amount of sugar in this food is just sufficient to cover the energy needs of the infant rat for about 2 hr., and it is thus obvious that the energy required for the remaining 22 hr. of the day must come either from fat or protein. This is underlined by the fact that liver and muscle glycogen content, although falling transiently shortly after birth, soon return to higher levels2.
