Abstract

The effects of serial milking on the zinc concentration of rat milk and in liver of the suckling young are reported. With consecutive milkings at 7, 14, and 21 days of lactation, the zinc content of rat milk on Day 21 was almost three times as high as that found in rats milked only once (on Day 21). This effect was also reflected in the sucklings; liver zinc concentrations found in pups from serially milked dams were twice those found in pups from dams not milked serially. The results show that serial milking cannot be used if the objective is the procurement of physiologically "normal" rat milk.
