Fat Excretion in Dogs Lacking Both Bile and Pancreatic Juice. ∗

Summary

In 6 dogs deprived of both pancreatic juice and bile and fed varying amounts of olive oil or oleic acid added to a control meal, the fat assimilative deficiency was approximately 60%. It was comparable in 3 dogs with bile deficiency. In 4 dogs lacking pancreatic juice, oleic acid was absorbed as well as in normal dogs. However, the assimilative deficiency for olive oil was nearly 50%. Apparently in the dog, mechanisms other than the actions of bile and pancreatic juice can account for the assimilation of approximately 40% of the dietary fat.
