How do I perform a fecal egg count on my horse?

Performing a fecal egg count on your horse is an essential part of managing their health and preventing parasitic infections. This process involves analyzing a sample of your horse’s manure to determine the number of parasite eggs present, helping you tailor deworming treatments effectively.

What is a Fecal Egg Count?

A fecal egg count (FEC) is a diagnostic test used to estimate the number of parasite eggs in a horse’s manure. This test helps identify the presence and intensity of parasitic infections, such as strongyles and ascarids, allowing you to develop a targeted deworming strategy.

Why is Fecal Egg Counting Important?

Regular fecal egg counts are crucial for effective parasite management. They help:

• Identify high shedders: Horses that shed a large number of eggs can be treated more aggressively.
• Prevent resistance: Overuse of dewormers can lead to drug-resistant parasites.
• Save costs: Targeted treatments reduce unnecessary medication expenses.
• Monitor effectiveness: Assess the success of deworming programs.

How to Perform a Fecal Egg Count on Your Horse

Performing a fecal egg count involves several steps. Here’s a simple guide to help you through the process:

Step 1: Collect a Manure Sample

1. Gather materials: You’ll need a clean, sealable plastic bag or container, a permanent marker, and gloves.
2. Collect fresh manure: Pick up a sample directly from the ground, ideally within a few hours of defecation. Aim for a sample size about the size of a golf ball.
3. Label the sample: Use a marker to write your horse’s name and the date on the container.

Step 2: Prepare the Sample for Testing

1. Mix the sample: Ensure the sample is well-mixed to provide an accurate representation.
2. Weigh the sample: Use a small scale to measure approximately 2 grams of manure.
3. Add flotation solution: Mix the manure with a flotation solution, such as a saturated salt or sugar solution, in a test tube or small container.

Step 3: Analyze the Sample

1. Centrifuge or let settle: If available, use a centrifuge to separate eggs. Alternatively, let the sample sit for 20-30 minutes.
2. Examine under a microscope: Place a drop of the solution on a microscope slide and cover it with a coverslip. Use a microscope to count the number of eggs in the field of view.
3. Calculate the egg count: Multiply the number of eggs counted by a factor to estimate the eggs per gram (EPG) of manure.

Step 4: Interpret the Results

• Low shedder: Less than 200 EPG
• Moderate shedder: 200-500 EPG
• High shedder: More than 500 EPG

Tailor your deworming program based on these results, focusing more on moderate and high shedders.

When to Perform a Fecal Egg Count

Perform fecal egg counts at least twice a year, ideally in the spring and fall. More frequent testing may be necessary for horses with high shedding levels or those in high-risk environments.

People Also Ask

How Often Should I Deworm My Horse?

The frequency of deworming depends on your horse’s fecal egg count results and environmental factors. Generally, horses should be dewormed 2-4 times a year, but always consult with a veterinarian for a personalized plan.

What is the Best Flotation Solution for Fecal Egg Counts?

Common flotation solutions include saturated salt, sugar, or zinc sulfate solutions. The choice depends on availability and specific parasite detection needs. Each solution has its benefits and limitations.

Can I Perform a Fecal Egg Count at Home?

Yes, with the right equipment and knowledge, you can perform a fecal egg count at home. However, for accurate results, consider having a veterinarian or laboratory perform the test.

Why is My Horse Still Showing Symptoms Despite Low Egg Counts?

Low egg counts might not always correlate with the absence of symptoms. Other factors, such as emerging larvae or non-parasitic issues, could be affecting your horse’s health. Consult a veterinarian for a comprehensive evaluation.

What Equipment Do I Need for a Fecal Egg Count?

Basic equipment includes a microscope, test tubes or containers, a flotation solution, and a scale. A centrifuge can improve accuracy but is not essential for basic counts.

Conclusion

Performing a fecal egg count is a practical step in maintaining your horse’s health. By regularly monitoring and interpreting these counts, you can develop a targeted deworming strategy that minimizes parasite resistance and ensures your horse’s well-being. For detailed guidance and accurate results, consider consulting with a veterinarian or professional laboratory.
