Commercial pig weaning at 3-4 weeks separates piglets from sows before natural weaning age, causing significant stress. Advanced management strategies can reduce the behavioral and physiological impact of this transition.
Early weaning is one of the most welfare-significant events in commercial pig production. Piglets simultaneously lose their mother, familiar environment, and primary nutrition source while facing an unfamiliar diet, new pen mates, and social reorganization. The resulting stress is measurable in cortisol levels, reduced growth rates, and increased disease susceptibility. Management strategies that buffer these transitions — earlier creep feed introduction, environmental enrichment, minimal mixing, and extended weaning age — represent evidence-based welfare improvements without compromising production viability.
