Dairy Heifer Welfare: Rearing for Longevity

An in-depth guide to dairy heifer welfare from birth to first calving, focusing on practices that support lifetime health and longevity.

Key Facts

Heifer rearing represents a significant welfare and economic investment
Colostrum management in the first 24 hours determines immune competence
Pneumonia and diarrhoea are the leading causes of calf mortality and welfare compromise
Social housing of calves improves welfare and cognitive development
Body weight and height targets predict first calving success and lifetime performance
Age at first calving affects lifetime health, welfare, and longevity

Welfare Considerations and Management

Welfare-centred heifer rearing begins with excellent colostrum management (4 litres within 2 hours of birth) and continues through appropriate housing, nutrition, and health management. Social housing from early life improves calf welfare and learning ability. Pre-weaning pneumonia control through good ventilation is critical. Nutrition programmes targeting appropriate growth rates (not excessive) without excess body condition support long-term welfare. First calving at 22-24 months in good body condition optimises lifetime performance and welfare.

What You Can Do

Ensure calves receive 4 litres of high-quality colostrum within 2 hours of birth
House calves in pairs or small groups from early life to support social development
Monitor growth rates regularly to ensure targets are being met appropriately
Target first calving at 22-24 months in body condition score 3.0-3.5
