Dairy Cow Metritis: Uterine Infection Welfare in the Transition Period

Puerperal metritis in dairy cows causes severe systemic illness in the days after calving, with fever, septicemia, and profound welfare compromise requiring prompt diagnosis and treatment.

Key Facts

Metritis affects an estimated 15-20 percent of dairy cows in the first two weeks after calving
It involves bacterial infection of the uterus causing foul-smelling discharge, fever, and toxemia
Risk factors include dystocia, retained placenta, twin birth, and negative energy balance
Severe metritis can progress to septicemia with multi-organ failure
Prompt antibiotic treatment reduces severity and duration of illness significantly

Welfare Considerations

Dairy cows with puerperal metritis experience acute and severe welfare compromise in the early postpartum period. High fever causes profound weakness, reduced appetite, and depression. The systemic toxemia from bacterial infection causes organ dysfunction that is clinically apparent as rapid deterioration in general condition. The combination of the normal metabolic stress of early lactation with the added burden of uterine infection creates a severe welfare crisis that requires intensive management. Untreated cows deteriorate rapidly and may die or require euthanasia. Even with treatment, recovery takes days to weeks during which welfare is significantly compromised.

What You Can Do

Implement daily monitoring of all cows in the first two weeks postpartum for metritis signs
Develop a written metritis treatment protocol with your veterinarian for prompt, consistent response
Address controllable risk factors including calving hygiene, assistance protocols, and energy balance
Ensure recumbent cows with metritis receive supportive care including assisted feeding and hydration
Review calving records to identify patterns in metritis incidence and address herd-level risk factors
Include metritis incidence in herd health monitoring as a welfare indicator
