Weaning strongly affects piglet intestinal microbiota
Separation with his mother, change of environment, change of feed: the weaning period is very disruptive for piglets. This stressful period also affects their intestinal microbiota.
These brutal changes lead to behaviour of anorexia, which reduce the development of intestinal villi. Weaning stress increases immune deficiencies and leads to the development of opportunistic infections. The accumulation of those disorders causes inflammations and diarrhoeas which have damaging consequences on piglet growth performance.
