Whey peptide increased short fatty chain acid levels. In elastase-instilled mice whey peptide increased total levels of SCFA (a), acetic acid (b), propionic acid (c) and butyric acid (d) while the increases were not proved by standard enteral diet. Results are expressed as mean ± standard deviation of mean and compared using Mann–Whitney U tests. The sham group consisted of phosphate buffered saline-instilled mice on a control diet
