Weaning is one of the most stressful events in a beef calf's life. Innovative management approaches can significantly reduce the acute stress of separation from the cow.
Weaning is an inherently stressful event for beef calves because it combines the disruption of an important social bond with a complete change in nutrition and often a change in physical environment. The acute distress of abrupt weaning — evidenced by intense, prolonged vocalisation and reduced feeding and rumination — represents a period of genuine suffering that can be significantly reduced through management innovation. Two-stage weaning with nose flaps, which prevents suckling while maintaining mother-calf contact for a transition period, is probably the single most effective welfare improvement available to beef cattle producers at low cost. The reduced immune suppression from lower stress weaning also has production benefits, providing economic incentives aligned with welfare improvement.
