Gastrointestinal development in pigs: implications for nutrition and performance

Code: 9781835451984
John O’Doherty, Dillon Kiernan and Torres Sweeney, University College Dublin, Ireland

Chapter synopsis:

This chapter discusses the pivotal developmental changes within a pig's gastrointestinal system (GIT) across various life stages, emphasizing their importance for achieving growth, health, and feed efficiency. The authors begin by describing how during the prenatal phase, the GIT experiences substantial growth, particularly in intestinal mass. They then examine how after birth, dynamic GIT changes occur, notably how establishment of the pig's intestinal microbiota begins shortly after birth. The authors next explore the challenges that weaning presents, including reduced feed intake, stress, and gut microbiota shifts affecting GIT's pH regulation, enzyme production, and intestinal barrier function. They then outline how dietary strategies can address these issues.
