Milk samples were taken from rats feeding ten pups and from both the suckled and non-suckled glands of rats feeding two pups. The lipid, protein and lactose concentrations were similar in the milks from the secreting glands, but the fluid from the non-suckled glands contained less lactose and lipid but significantly higher total protein and transferrin concentrations. The fatty acid compositions of the milk from the three sources were very similar. The mammary tissue from the rats feeding ten pups had a higher DNA content/g wet wt. than either the suckled or non-suckled mammary tissue of the rats feeding two pups. The specific activities of several lipogenic enzymes were significantly lower in the non-suckled mammary tissue.
