1. The absorption of zinc by the duodenum of the rat was greatly enhanced at late stages of pregnancy and during lactation.

2. During pregnancy no increase in lysine uptake could be demonstrated, but during lactation, when further increases in Zn absorption occurred, uptake of lysine was increased.

3. The increased absorption of Zn at different stages of pregnancy and lactation appeared to be related to the demand made by the developing foetuses and post-natal offspring.
