A minimum value for fat, protein, and vit. A occurred about the 27th day, while reducing sugar showed the opposite trend, being highest about the 30th day. A sharp rise occurred in the Ca/P ratio at the end of lactation. Flavin decreased during heavy lactation, rising as the pups received additional food but decreasing again when the pups were removed.
