High Fat Feeding of Lactating Mice Causing a Drastie Reduction in Fat and Energy Content in Milk without Affecting the Apparent Growth of Their Pups and the Production of Major Milk Fat Globule Membrane

was apparently no significallt difference in the growth of the pups raised by either diet greup. This discrepancy might be in part explained by a hypothesis that the pups might moniter calorie contellt in milk and keep sllckling until the energy intake reaches their satisfaction. Moreover, nearly the same amounts of major milk fat globule membrane proteins MFG-E8 and blltyrophilin were shown to be
