Building healthy, well-adapted dairy cows starts with welfare-conscious rearing
Dairy heifer rearing — raising female calves from birth to first calving — spans approximately 24 months and determines lifetime welfare, productivity, and longevity. Welfare problems established during rearing, including social isolation, nutritional restriction, painful procedures, and inadequate space, have lasting effects. Welfare-conscious rearing produces cows that are healthier, calmer, more productive, and longer-lived.
The standard practice of individual calf housing was based on disease control logic, but research from Cornell, Wageningen, and other institutions consistently shows pair-housed calves outperform individually-housed calves on behavioral, physiological, and production measures. EU regulations now require that calves over 8 weeks cannot be individually housed except on veterinary advice.
Conventional dairy calf rearing severely restricts milk intake (4-6 L/day) far below the calf's natural intake (8-12 L/day). This causes chronic hunger, cross-sucking, and poor welfare. Enhanced milk feeding (ad libitum or near-ad libitum) produces better welfare, better growth, and better lifetime productivity. The welfare and economic cases for enhanced feeding are now both strong.
