Critical Success Factors

Ventilation

Pneumonia is the #1 killer. Your shed needs:

  • Fresh air in, moist air out
  • No drafts at calf level
  • Dry bedding always
  • Space: 2m² per calf minimum
Feeding Protocol

Consistency beats everything.

  • Same person feeds if possible
  • Same time ±15 minutes
  • Correct temperature (38-40°C)
  • Clean equipment EVERY time
Health Monitoring

Catch it early or pay the vet.

  • Check temperatures daily first week
  • Isolation pen ready always
  • Know your normal vs sick signs
  • Have electrolytes & vaccines ready

The Truth About Calf Rearing: From Another Young Farmer

"My first year, I lost 3 calves in a week. Pneumonia. I was feeding them, but the shed was damp. €1,200 gone. I nearly quit."

"Year 2, I followed a system. Dry bedding every morning. Fans for ventilation. Exact feeding times. Record keeping."

"That year, 29 out of 30 calves weaned. The sick one recovered in 3 days because I caught it early. That's the difference: system over guesswork."

"Now I buy 50 calves every spring. It's hard work, but the numbers work. At 8 months, they're worth triple what I have in them. That's how you build a farm."

The secret isn't magic. It's doing the simple things right, every single day.
