Five barrows were fitted with permanent pancreatic re‐entrant cannulas to determine the influence of diet on exocrine pancreatic secretions in the weight range from 40 to 65 kg. The pigs were fed four diets. Diets 1 and 2 were based on corn starch and contained 18.6 and 16.9 % crude protein (dry matter basis) from soybean meal and canola meal, respectively. Diets 3 and 4 contained 93.9 % wheat and barley, respectively. In the same order, the crude protein contents (dry matter basis) of these diets were 14.4 and 11.2%, respectively. The experiment was carried out according to 4 × 4 Latin square design. Each experimental period comprised 12 days. Following an adaptation period of 8 days, pancreatic juice was collected from 08:00 on day 9 to 08:00 h on day 10 and from 08:00 on day 11 to 08:00 h on day 12. The pigs were fed twice daily, at 08:00 and 20:00 h, 800 g each meal. Despite large differences, up to 23%, between the overall mean values of the parameters that were measured there was no effect ( P > 0.05) of diet on the volume of secretion of pancreatic juice, the pH and the secretion of total and TCA‐precipitable nitrogen. Due to the high level of within‐study variation there was also no effect ( P > 0.05) of diet on the secretion of amino acids and the total activity of trypsin, chymotrypsin, α‐amylase and lipase in pancreatic juice.
