Nutritional supplementation during the post-weaning transition period represents one of the highest-impact welfare interventions in pig production, reducing the incidence and severity of welfare-compromising post-weaning diarrhea.
Post-weaning nutrition welfare reflects the compounding challenge of managing a transition that is physiologically stressful regardless of nutritional intervention quality. The best nutritional programs reduce but cannot eliminate the welfare cost of early weaning — demonstrating that nutritional management cannot fully substitute for the welfare improvement that later weaning ages provide. Both dimensions deserve attention: improving post-weaning nutrition within current production systems while advocating for later weaning ages that reduce the baseline stress the nutritional interventions are trying to manage.
