Fecal egg counts (FECs) are a valuable tool in the deworming process for horses, providing insights into parasite load and helping to tailor treatment plans. By analyzing the number of parasite eggs in a horse’s manure, owners can make informed decisions about their deworming strategies, ensuring effective treatment while reducing the risk of resistance.
What Are Fecal Egg Counts?
Fecal egg counts measure the number of parasite eggs per gram of feces. This test helps identify the presence and severity of internal parasites, primarily strongyles and ascarids, in horses. A veterinarian or a trained professional typically performs FECs by examining a manure sample under a microscope.
Why Are Fecal Egg Counts Important?
- Targeted Deworming: FECs allow for a more targeted approach to deworming, reducing unnecessary treatments.
- Prevent Resistance: Regular FECs can help prevent the development of resistance to dewormers by avoiding overuse.
- Monitor Effectiveness: They provide a way to assess the effectiveness of deworming treatments.
How to Perform Fecal Egg Counts
Collecting a Sample
To perform a fecal egg count, collect a fresh manure sample, ideally within 12 hours of defecation. Store the sample in a sealed plastic bag and refrigerate it if it cannot be analyzed immediately.
Analyzing the Sample
A veterinarian or laboratory will analyze the sample. The process involves mixing the feces with a flotation solution, which makes the eggs float to the surface for counting under a microscope.
Interpreting Results
- Low Shedders: Less than 200 eggs per gram (EPG)
- Moderate Shedders: 200-500 EPG
- High Shedders: More than 500 EPG
These categories help determine the frequency and type of deworming treatment needed.
Benefits of Fecal Egg Counts for Deworming
Customized Deworming Programs
FECs enable the creation of customized deworming programs tailored to individual horses. This approach prevents the unnecessary use of dewormers and focuses on horses that need treatment.
Reducing Dewormer Resistance
Overuse of dewormers can lead to resistance, making these medications less effective over time. By using FECs, horse owners can strategically target treatments, preserving the efficacy of dewormers.
Cost-Effective Management
Targeted deworming based on FEC results can be more cost-effective than routine blanket treatments. It reduces the frequency of treatments and the amount of dewormer needed.
Practical Examples and Case Studies
Case Study: Farm A
Farm A implemented a fecal egg count program and found that only 30% of their horses required deworming. This targeted approach reduced their deworming costs by 40% annually and improved overall herd health.
Example: Horse B
Horse B, a high shedder, showed a significant reduction in EPG after a targeted deworming treatment. Regular FECs helped maintain low egg counts, reducing the risk of pasture contamination.
People Also Ask
How Often Should Fecal Egg Counts Be Done?
Fecal egg counts should be done at least twice a year, ideally in spring and fall. High shedders may require more frequent testing to monitor parasite levels effectively.
What Are the Limitations of Fecal Egg Counts?
FECs primarily detect strongyle and ascarid eggs but may not identify all types of parasites. Additionally, they do not detect immature or encysted larvae, which can also impact a horse’s health.
Can Fecal Egg Counts Replace Deworming?
FECs do not replace deworming but complement it by providing data to guide treatment decisions. They help ensure that deworming is necessary and effective.
What Is the Cost of a Fecal Egg Count Test?
The cost of a fecal egg count test varies but typically ranges from $15 to $30 per test. This investment can lead to long-term savings by optimizing deworming strategies.
Are Fecal Egg Counts Reliable?
FECs are reliable for assessing adult parasite burdens but should be used in conjunction with other health assessments. Consulting with a veterinarian ensures the most accurate interpretation.
Conclusion
Fecal egg counts are an essential tool in the effective management of equine parasites. By providing a clear picture of a horse’s parasite load, FECs enable targeted and efficient deworming strategies. This approach not only enhances the health of individual horses but also contributes to the broader goal of preventing dewormer resistance.
