🔍 Decode the Danger: What’s Causing the Drip?

(Stool Color = Your Clue!)
Decoding Calf Stool: When to Worry & Act

1. Yellow & Frothy

  • Cause: Rotavirus or Cryptosporidium ("Crypto")

  • Action: 🟡 Moderate urgency – Call vet within 12 hours.

2. White/Grey & Pasty

  • Cause: E. coli or Salmonella infection

  • Action: 🔴 HIGH urgency – Vet needed IMMEDIATELY.

3. Bloody or Black/Tarry

  • Cause: Coccidiosis or Clostridium (often fatal)

  • Action: 🔴🚑 ICU-LEVEL EMERGENCY – Rush to clinic.

4. Green & Watery

  • Cause: Nutritional scours (milk replacer issues, overfeeding)

  • Action: 🟢 Monitor + adjust feeding; home care usually sufficient.

💡 Pro Tip: The "Sniff Test"

  • Rotten egg smell? → Suspicious for Clostridium (deadly toxin risk).

  • Sweet, foul odor? → Often signals E. coli infection.

Always isolate sick calves, provide electrolytes, and track symptoms. When in doubt – CALL YOUR VET.

🏡 Immediate Home Care (Do This FIRST)

While waiting for the vet—support survival:

  1. Hydrate or Die 💧

    • Electrolyte Recipe:

      • 1L warm water + 1 tsp salt + 1 tsp baking soda + 2 tbsp glucose/sugar + 1 mashed banana (for potassium).

    • Offer 2–3L/day via bottle or tube.

  2. Probiotic Power 🦠

    • Plain yogurt (2 tbsp/feeding) or calf-specific probiotics (e.g., Pro-Tect Quick Fix).

  3. Belly Soothers 🌿

    • Kaolin Clay: 30g mixed in milk (binds toxins).

    • Slippery Elm Tea: Steep 1 tbsp in hot water, cool, syringe 100ml 3x/day.

  4. WARMTH IS LIFE 🔥

    • Calf jackets + heat lamps if temp <38°C (100.4°F). Cold calves can’t absorb fluids.

❌ DANGER: Home Remedies to AVOID

  • Human anti-diarrheals (e.g., Imodium) – Lethal to calves.

  • Essential oils – Toxic to liver.

  • Withholding milk – Starvation worsens dehydration.

🆘 10 Life-or-Death FAQs
  1. Q: Can scours kill a calf overnight?
    A: YES. Dehydration shuts organs in 12–24hrs. Electrolytes BEFORE vet!

  2. Q: Should I stop milk feeding?
    A: NEVER! Feed ½ milk + ½ electrolytes every 4 hrs. Malnutrition kills faster.

  3. Q: Is bloody diarrhea always coccidiosis?
    A: No! Clostridium (enterotoxemia) causes black tarry blood → needs ANTITOXIN ASAP.

  4. Q: Can I use human electrolytes?
    A: Risk! Human formulas lack bicarbonate. Use calf-specific (e.g., Rehydran).

  5. Q: How to check for dehydration?
    A: Skin tent test: Pinch neck skin >3 sec? Sunken eyes?EMERGENCY.

  6. Q: Are scours contagious?
    A: Extremely! Isolate calf, disinfect boots/buckets with Virukill.

  7. Q: Can probiotics replace antibiotics?
    A: NO. Probiotics support, antibiotics kill pathogens. Use both!

  8. Q: Why is my calf shivering?
    A: Hypothermia or sepsis. Normal temp: 38.5–39.5°C. <37.5°C = CRISIS.

  9. Q: Cost to treat scours?
    A: R300–R2,000 (meds + IV). Prevention is 10x cheaper!

  10. Q: When to call the vet?
    A: IMMEDIATELY if: Blood in stool, unable to stand, temp >40°C or <37.5°C.

💛 Final Thought: The Farmer’s Vigil

Scours test us like nothing else. I’ve held calves at midnight, syringing electrolytes into limp mouths, praying for a swallow. Sometimes we win. Sometimes we weep. But every battle teaches this truth:

“Courage isn’t knowing if they’ll live—it’s fighting like they will.”
