Role of low dietary fat in the treatment of dogs with exocrine pancreatic insufficiency.

Abstract

The main objective of the study reported here was to determine whether signs typical of exocrine pancreatic insufficiency (EPI) are alleviated when affected dogs are fed a diet with low fat content, compared with feeding ordinary commercial dog food or food prepared by the owner. The most cost-effective amount of enzyme supplement also was estimated. The study consisted of 6 test periods. Duration of the first and third periods was 4 weeks, and that of the others was 2 weeks. During the first 2 periods, the dogs were fed their original diet. The amount of enzyme supplement was reduced by half between the first and the second period. During the last 4 periods, the dogs were fed only the low-fat diet, and amount of the enzyme supplement was reduced stepwise. During the entire study, owners were asked to assess daily the severity of 9 signs typical of EPI. A new index was established by adding the daily scores of each individual EPI sign. This index was designated the EPI index and was used as a measure of the general well-being of the dog. When the mean EPI indexes of the original diet periods were compared with those of the corresponding low-fat diet periods, there were no statistically significant differences by use of Tukey's test or the paired t-test. There was considerable variability between dogs, however. The fat content of the original diet did not correlate with the difference in EPI signs when the dogs were fed the low-fat diet.(ABSTRACT TRUNCATED AT 250 WORDS)
