Transition Cow Welfare: The Critical Periparturient Period in Dairy Farming

The transition period around calving is the highest-risk phase for dairy cow health and welfare. Managing this period well prevents most major metabolic and infectious diseases.

Key Facts

The transition period spans three weeks before to three weeks after calving and is associated with the highest disease and mortality rates in dairy cows
Negative energy balance occurs as milk production increases faster than feed intake can compensate after calving
Metabolic diseases including milk fever, ketosis, and displaced abomasum occur predominantly in the transition period
Milk fever (hypocalcaemia) occurs in 5-10% of cows at calving and causes muscle weakness, recumbency, and death if untreated
Ketosis affects up to 40% of dairy cows in the early lactation period and causes anorexia, reduced milk production, and liver damage
Overcrowding in pre-calving pens increases stress, reduces lying time, and is associated with increased transition disease rates
Feeding management in the close-up period is the most critical preventive intervention for metabolic disease
Cows that experience difficult calvings (dystocia) have significantly higher rates of retained placenta, metritis, and reduced fertility

Welfare Considerations

Transition cow welfare represents one of the highest-impact welfare intervention opportunities in dairy farming. The concentration of multiple serious health risks in a six-week window means that good transition management prevents a disproportionate share of total cow suffering. Metabolic disease causes genuine suffering: milk fever results in paralysis and the inability to rise; ketosis causes anorexia and progressive liver dysfunction; mastitis from immune suppression causes painful udder inflammation. Preventing these conditions through nutritional management, appropriate space allowance in pre-calving pens, early disease detection, and prompt treatment directly improves welfare for millions of cows annually. Transition management is also one of the clearest alignments of welfare and productivity in dairy farming: healthy cows produce more milk and remain in the herd longer.

What You Can Do

Support dairy welfare standards that include transition cow management requirements
Choose dairy from farms with transparency about disease rates including ketosis and milk fever incidence
Advocate for pre-calving pen space allowance requirements in welfare certification schemes
Learn about transition cow health and share why this period is so critical for dairy cow welfare
Support research into cost-effective transition management interventions for smaller dairy operations
Reduce dairy consumption from operations with no welfare transparency to create market incentives
Engage with dairy industry groups to promote transition cow welfare as a priority management area
