Mastitis in Cows: When to Bottle-Feed the Calf and Best Practices

In severe clinical mastitis, temporary calf separation and bottle-feeding may be necessary. Decision: always consult the herd veterinarian.

Indications for Separation

• Severe systemic signs: Fever, toxemia, inappetence, marked udder inflammation
• Calf unable to nurse: Weakness, injury, anatomical defect
• High contagion risk: Staph. aureus, Mycoplasma, Strep. agalactiae—pathogens transmissible via milk
• Abnormal milk: Pus, blood, clots, watery—unsafe for calf consumption

Bottle-Feeding Protocol

1. Colostrum first: Ensure adequate IgG transfer (test serum total protein or Brix refractometer).
2. Milk handling: Pasteurize (60°C/60 min) or use milk replacer if pathogen risk high.
3. Hygiene: Sterile bottles, nipples; clean prep area.
4. Feeding schedule: 2–3 quarts, 2–3x/day; monitor intake, weight gain.

Reintroduction

As cow recovers (clinical signs resolve, SCC declines), gradually reintroduce calf under veterinary guidance. Monitor both for health.

Goal: Protect calf, maintain cow productivity, minimize economic loss.
