Neonatal Calf Mortality Prevention and Welfare

Neonatal calf mortality in the first week of life represents significant welfare harm. Prevention through management and early intervention reduces both suffering and losses.

Key Facts

Up to 5% of UK dairy calves die within the first week of life
Hypothermia, failure of passive transfer, and scour account for most neonatal calf mortality
Inadequate colostrum quality or quantity predisposes calves to fatal infections
Hypothermia in newborns can be reversed if detected within hours with warming and warming box
Electronic colostrum refractometers ensure colostrum quality before feeding

Welfare Considerations

Neonatal calf welfare in the first critical days depends on rapid colostrum absorption, protection from cold, and prompt treatment when problems develop. Hypothermic calves that are found quickly, dried, warmed in a warming box, and given colostrum via stomach tube can recover fully. Calves in whom failure of passive transfer is identified at 18-24 hours can receive plasma transfusion. Prevention through monitoring calving cows closely, ensuring calves receive colostrum within 6 hours, and keeping calving pens clean and draught-free prevents most neonatal mortality.

What You Can Do

Monitor calving cows closely to ensure calves receive colostrum within 2-6 hours
Use a Brix refractometer to verify colostrum quality before feeding
Provide warming boxes for hypothermic calves and dry them rapidly after birth
Support training programmes for farmers in neonatal calf care and resuscitation
