Lactating mice were fed either a low fat or a high fat diet. Milk samples were collected and the composition was examined. Triglyceride and free fatty acid contents were greatly reduced in the milks of high fat diet group, while protein and lactose contents were almost the same between both diet groups. Although the energy content of each component was also lower in milk of high fat diet group, there was apparently no significant difference in the growth of the pups raised by either diet group. This discrepancy might be in part explained by a hypothesis that the pups might monitor calorie content in milk and keep suckling until the energy intake reaches their satisfaction. Moreover, nearly the same amounts of major milk fat globule membrane proteins MFG-E8 and butyrophilin were shown to be present in the milks from both diet groups and gene expression of both proteins in the mammary glands were also indistinguishable, suggesting that production of major MFGM components is not simpl
