1. Two sows were housed in farrowing crates with slotted floors and fed daily with approximately 200 μCi 198Au from 3 d before farrowing until their piglets were 21 d old.

2. The sows' faeces became radioactive but their milk remained free of radioactivity. The piglets' mean (±SE) whole-body radioactivity was equivalent to 8·5 ± 0·9 g (range 3·8–15·5 g) of faeces. This is probably a measure of their daily intake of faeces.

3. The possibility of using this natural coprophagia to prevent piglet anaemia has been demonstrated on two commercial piggeries by feeding the sows a diet containing 2000 mg Fe/kg.
