“…In contrast to our results, Johnson et al. () found that duodenal infusions with coconut or safflower oils significantly reduced protein concentration in bile–pancreatic juice. According to Majewska et al.…”

“…Moreover, cholinergic nerves, stimulating the motor activity of the initial part of the duodenum, play an essential role in this process. Our results are in contrast with those obtained by Johnson, Mitchell, Tucker, and Schelling (), who showed significantly decreased bile‐pancreatic juice secretion in animals with duodenally infused coconut or safflower oils in comparison with control ones (61.0 or 61.5 vs 69.5 ml/hr).…”

“…In contrast to our data, Johnson et al. () found significant decrease in pancreatic lipase activity after duodenal infusions of highly saturated oil (coconut). These authors used different sources of triglycerides as lipid substrates for ovine lipase and observed that butterfat and coconut oil were hydrolyzed more rapidly than olive, corn and safflower oils as well as beef tallow.…”

“…In contrast to our results, Johnson et al (1974) found that duodenal infusions with coconut or safflower oils significantly reduced protein concentration in bile-pancreatic juice. According to Majewska et al (2013), protein concentration in pancreatic juice may be dependent on the protein degradation rate in the rumen.…”

The aim of this study was to compare the effect of rapeseed and linseed oils added to the diet on pancreatic enzyme activities in sheep. The experiment was conducted on six adult sheep with a catheter introduced into the common bile-pancreatic duct and a T-cannula into the duodenum. The animals were divided into three groups, two sheep in each. A twice-replicated 3 × 3 Latin square was used in the experimental design. The sheep were fed meadow hay and the concentrate alone or the same ration supplemented with rapeseed or linseed oils at a dose of 5% of the basal diet. After adaptation period, a mixture of pancreatic and bile juice was collected for three consecutive days. The secretion of bile-pancreatic juice showed an increasing trend in sheep fed rapeseed and linseed oils (69.5 and 68.5 ml/hr respectively) in comparison with control ones (59.8 ml/hr). Lipase and trypsin activities were significantly increased when sheep were fed diets with rapeseed or linseed oils (175 and 21.6 or 179 and 23.2 U/L respectively) in comparison with those fed control diet (128 and 13.1 U/L respectively). It was concluded that oil as a dietary supplement can mainly modify the secretion of bile-pancreatic juice and enzymatic activity of the pancreas and also might affect animal production.

“…In sheep MAGEE (1961) reported that the p H of duodenal chyme is an important regulator of pancreatic activity. It is now clear that the gland may be stimulated through hormonal and nervous pathways; the maintenance of the normal rate of secretion depends mainly on the release from the intestinal wall of a humoral agent (TAYLOR, 1962;HARRISON and HILL, 1962;AUST and COOK, 1968;CLARY et al, 1969;JOHNSON et al, 1974;ARIENTI et al, 1974).…”
