Weaning stress in commercial pig production is a major welfare challenge, as early weaning ages cause significant physiological and behavioral distress that advanced management approaches can reduce.
Weaning stress management addresses one of the most welfare-significant transitions in commercial pig production. The abrupt separation of piglets from sows at ages far earlier than natural weaning creates simultaneous physiological and behavioral challenges — digestive system immaturity, immune vulnerability, loss of social comfort and cessation of nursing all occurring simultaneously. Advanced management reduces welfare impact through older weaning ages, gradual dietary transition using creep feeding, enriched transition environments, and careful group composition management. The welfare case for later weaning ages is strong and the commercial case, through reduced antibiotic use and improved piglet performance, is increasingly recognized by the industry.
