Transition Cow Welfare: Calving and Early Lactation

The transition period around calving is the highest risk period for dairy cow health and welfare, requiring intensive management to prevent metabolic disease.

Key Facts

The transition period spans three weeks before and after calving
Hypocalcaemia (milk fever) affects up to 25 percent of cows in some herds
Ketosis results from inadequate energy supply relative to lactation demands
Displaced abomasum is most common in the first two weeks post-calving
Transition cow management directly affects the entire subsequent lactation

Welfare Considerations

Transition cows face a cascade of metabolic challenges as they shift from dry period to early lactation. Milk fever causes rapid collapse and, without treatment, death. Subclinical hypocalcaemia is far more common and reduces immune function, increasing susceptibility to mastitis and metritis. Ketosis causes nausea, reduced appetite, and altered behavior. Liver disease from fat mobilization compounds the welfare impact. Management strategies including pre-calving calcium supplementation, dietary cation-anion balance adjustment, and early ketosis detection through ketone monitoring reduce the welfare burden of transition disease significantly.
