Pigs fed hLZ-milk had less ETEC-induced intestinal damage at the end of the experiment.

<p>Histological sections at 10X magnification showing average villi from the ileum of pigs (<b>A</b>) fed hLZ-milk or (<b>B</b>) control milk. Pigs fed hLZ-milk had reduced damage due to ETEC infection as seen by increased surface area (taller villi) and less inflammation (thinner lamina propria), compared to pigs fed control milk.
