The growth and health of piglets is reduced directly after weaning because of high incidence of diarrhoea.
Feeding low doses of seaweed to piglets may positively affect gut health and reduce diarrhoea. It will also supply several minerals.
• Effectivity might differ depending on the seaweed type, harvest season and processing method. Brown and red seaweed species may be better than green.
• Several commercial seaweed products can be used, and it is important to ask for documentation of effect before relying on e.g. effect on diarrhoea.
• High levels of macro and micro minerals have to be taken into account when composing diets with seaweed.
• Many seaweed extracts are available, which may not be suitable for organic production.
