How natural and extended weaning approaches in pig farming reduce welfare harm and what commercial implementation looks like.
Natural weaning approaches in pigs demonstrate that the welfare harm of conventional abrupt early weaning is not an inevitable feature of pig farming but a consequence of specific production choices. Systems that allow gradual, later weaning — whether through family pens, lactation feeding systems, or simple later weaning ages — show measurably better welfare outcomes for both sows and piglets across multiple indicators. The production implications are real and require management adaptation, but commercial viability has been demonstrated in pilot programmes. The welfare argument for extended, natural weaning is compelling: it reduces one of the most significant acute welfare events in commercial pig production without sacrificing the viability of the farming operation.
