Abstract Progeny of primiparous sows (gilts) have poor production performance compared to those of multiparous sows. This has been attributed to underlying biological events that occur early in life. We specifically focused on the development of the gastrointestinal tract (GIT) and its function in sow vs gilt progeny (SP vs GP) reared under commercial conditions. Piglet tissues were harvested at birth, at 24 h, and pre- and post-weaning (28 v 29 d) and used to quantify GIT integrity. All data were analysed using Genstat V18 for the effects of parity (sow vs gilt) in birth (0 vs 24 h) and weaning (pre- vs post) cohorts. GIT integrity was quantified from freshly excised tissue i..View full abstract
