Abstract

Progeny from primiparous sows (gilt) have lower birth weights, higher mortality and poorer performance than the progeny from multiparous sows. The reasons for this are complex but may involve poorer quality colostrum and impaired gastrointestinal tract (GIT) barrier function. With evidence that events early in life impact whole‐of‐life mortality and productivity the aim of this experiment was to investigate the influence of sow parity on piglet and GIT development at birth and weaning. The experiment comprised of 72 mixed gender Large White x Landrace piglets from parity 2–3 sows (SP) vs gilts (GP). Piglets were euthanased at birth (pre‐suckle), 24 h, pre‐weaning (PW,~28 d.) and 24 h after w..
