Using FAMACHA to Assess Goat Health

The FAMACHA method is a simple and effective tool for monitoring anemia in goats, particularly caused by blood-sucking parasites like the Barber Pole worm (Haemonchus contortus). Here’s a detailed guide:

What is FAMACHA?

• FAMACHA Scoring: A method to evaluate the color of a goat’s lower eyelid to assess anemia levels.
  • Bright pink/red: Healthy, no anemia.
  • Pale pink/light pink: Mild anemia, possible parasitic load.
  • White or very pale: Severe anemia, urgent treatment required.
• Targeted Use: FAMACHA is specifically for identifying blood-sucking worms, such as the Barber Pole worm, but does not detect food-consuming parasites. Other diagnostic methods, like fecal samples, are necessary to identify those.

Step-by-Step FAMACHA Check

1. Prepare the Goat:
   • Calm the goat and secure it safely.
   • Ensure proper lighting for accurate eyelid color evaluation.
2. Examine the Eyelid:
   • Use your thumb to gently pull down the lower eyelid.
   • Look at the inner surface of the eyelid for color.
3. Interpret the Results:
   • Bright Pink: No signs of anemia; the goat likely has no significant blood-sucking parasitic infection.
   • Light Pink: Moderate anemia; consider treatment and check for Barber Pole worms.
   • White or Pale: Severe anemia; requires immediate deworming and supportive care.
4. Record Findings:
   • Document the FAMACHA score as part of the goat’s health records for regular monitoring.

When FAMACHA is Not Enough

• Non-Blood-Sucking Parasites:
  • FAMACHA does not detect parasites that consume food rather than blood. For these, fecal testing is essential.
  • Fecal samples help identify eggs or parasites like coccidia, which impact a goat’s gut and overall health.

Common Indicators of Parasite or Mineral Deficiency

1. Hair Quality:
   • Poor coat condition (coarse texture, uneven growth, lack of shine) can indicate mineral deficiencies or other underlying health issues.
2. Body Condition:
   • Monitor weight and body condition. A thin goat with poor coat quality may need nutritional or parasitic intervention.
3. Testing for Confirmation:
   • Send fecal samples to a lab for detailed analysis.
   • Use mineral supplements or multi-mineral injections to address deficiencies.

Action Plan Based on FAMACHA Results

1. No Anemia (Bright Pink):
   • Continue regular health checks and pasture rotation.
   • Ensure access to balanced minerals and nutrition.
2. Mild Anemia (Light Pink):
   • Deworm using appropriate medications.
   • Consider multi-mineral injections if poor coat quality or low mineral intake is suspected.
3. Severe Anemia (White/Pale):
   • Immediate Deworming: Use effective dewormers targeting blood-sucking worms (e.g., Barber Pole worms).
   • Supportive Care: Administer anemia treatments, such as Red Cell or iron supplements, and monitor recovery.

Additional Notes

• Hair as a Health Indicator:
  • Healthy goats have sleek, shiny coats. Poor coat quality often signals underlying issues like parasites or mineral deficiencies.
• Mineral Absorption:
  • Not all goats consume enough minerals. Multi-mineral shots can provide a direct boost to those not grazing or consuming loose minerals adequately.
• Fecal Testing:
  • Always complement FAMACHA checks with fecal testing to get a full picture of the goat’s health.

Conclusion

FAMACHA is a vital tool in goat herd management, offering a quick and cost-effective way to detect and address anemia caused by blood-sucking worms. Combined with regular fecal testing, nutritional supplements, and proactive health monitoring, you can maintain a healthy and productive goat herd.
