Abstract
The mean apparent absorption of sulphur when sodium sulphate was continuously infused into the rumen or the duodenum of four sheep in amounts of 1� 5, 3�0, and 6�0 g/day was 93 �1, 95�3, 95�9% and 93 �1, 92,8, 81� 5% respectively. The net absorptive capacity of the entire intestine under these conditions was calculated to be up to 5 g of sulphate sulphur daily.
