The effects of feeding two very differently composed fibre-rich diets and a low dietary fibre (DF) diet on the rate of gastric emptying were examined in six gastric-cannulated pregnant sows. The stomach contents were evacuated through the gastric cannula once daily. Increasing the content of DF in the diet led to higher recoveries of liquid digesta but did not have any effect on the gastric emptying of dry matter (DM) and dietary components. The type of DF in the diet did not have a major influence on the results of the study.
