Parasite Control Testing for Goats

This lesson focuses on the critical role of testing in managing parasite control for your goat herd. By regularly testing fecal and blood samples, you can monitor parasite loads, identify specific issues, and administer targeted treatments, ensuring the health and well-being of your goats.

Key Topics Covered:

• Why Testing is Essential
  • Testing eliminates guesswork in diagnosing parasite issues and determining treatment needs.
  • Regular tests provide a clear picture of herd health, especially for common parasites like Barber Pole Worm, stomach worms, and coccidia.
• Types of Tests and Labs
  • Fecal Testing:
    • Identify parasite types and loads.
    • Recommended lab: MidAmerica Ag Research (midamericaagresearch.net).
    • Results are typically returned within two days.
  • Blood Testing:
    • Diagnose issues like CAE, CL, and other health concerns.
    • Recommended lab: Sage Labs.
    • Results are typically returned within three days.
• Steps for Fecal Testing
  1. Collect fresh fecal samples: Look for goats lying down, as they typically defecate shortly after standing.
  2. Gather 6–7 fecal pellets per goat in labeled Ziploc bags.
  3. Send samples to a reputable lab for analysis.
  4. Use results to determine whether treatment is needed and what type of dewormer to use.
• Interpreting Fecal Results
  • Labs provide egg counts and parasite types.
  • Egg count thresholds:
    • 1–10 eggs: Low concern, monitor health and condition.
    • 11–50 eggs: Moderate concern, consider treatment if health issues are evident.
    • 50+ eggs: High concern, treatment is strongly recommended.
  • For low or moderate counts, focus on strengthening goats’ immune systems before considering retreatment.
• Common Parasites and Their Control
  • Barber Pole Worm (stomach worm):
    • Common in pregnant does, often blooms heavily around kidding.
    • Treat with dewormers like Ivermectin or Valbazen based on lab results.
  • Coccidia:
    • Common in kids, causing diarrhea.
    • Treat with sulfa-based medications like Albon or SMZs.
    • Presence in adult goats often indicates mineral deficiencies or heavy worm loads.
• Testing Frequency and Herd Size Considerations
  • For large, active herds: Test regularly (e.g., twice a year) to maintain control over parasite loads.
  • For small, closed herds: Test occasionally to ensure herd health.
  • Always test new goats entering the herd before integration.
• Key Benefits of Testing
  • Prevents overuse of dewormers and reduces risk of resistance.
  • Allows for targeted treatment rather than blanket deworming.
  • Supports long-term herd health and reduces management costs.

Conclusion:

Parasite control testing is an indispensable tool for maintaining a healthy goat herd. Regular fecal and blood tests provide accurate data to guide treatment decisions, reducing the risks of overmedication and resistance. By understanding and interpreting lab results, you can implement effective parasite management strategies, ensuring the health and productivity of your goats. Take advantage of reputable labs and online resources to stay informed and proactive in managing parasites.
