Deworming Calves: Why Timing Matters for a Healthy Start

When it comes to raising healthy calves, one often overlooked but crucial step is early deworming. Internal parasites like worms can silently rob your young calf of nutrition, energy, and growth potential.

🕒 When Should You Deworm a Calf?

Experts recommend the first deworming at 3 to 4 weeks of age. By this time, the calf’s immune system is still developing, and if it’s in contact with contaminated bedding or grazing pastures, parasites can quickly become a problem.

🔄 What’s the Deworming Schedule?

• First dose: At 3–4 weeks of age
• Follow-up doses: Every 6–8 weeks, or as advised by your vet
• Weaning stage: Deworm again during or just after weaning
• After grazing: Deworm before turning out to pasture and after grazing seasons

💊 What Dewormers Should You Use?

Common deworming medications include:

• Albendazole
• Fenbendazole
• Ivermectin

Always follow your vet’s advice for correct dosage, especially based on the calf’s weight and age.

⚠️ Why It’s Important:

• Boosts weight gain and growth rate
• Prevents diarrhea and stunted development
• Strengthens the calf’s immune system
• Prepares the calf for a productive life ahead

✅ Final Tip:

Even if your calf looks healthy, worms might still be inside, affecting performance. Preventive deworming is far more effective than treating after visible damage is done.
