Oral treatment with Lactococcus lactis expressing Staphylococcus hyicus lipase enhances lipid digestion in pigs with induced pancreatic insufficiency

The Staphylococcus hyicus lip gene was cloned in Lactococcus lactis. Pancreatic insufficiency was induced by ligation of the pancreatic duct in pigs. In pigs who had undergone pancreatic ligation, the coefficient of fat absorption was higher after consumption of lipase-expressing L. lactis (91.9% +/- 3.7%) than that after consumption of the inactive control strain (78.4% +/- 2.4%).
