A fecal egg count in horses is a diagnostic test used to measure the number of parasite eggs in a horse’s manure. This test helps horse owners and veterinarians determine the level of parasitic infection and decide on appropriate deworming strategies.
What is a Fecal Egg Count and Why is it Important?
A fecal egg count (FEC) is a laboratory test that quantifies the number of parasite eggs present in a gram of a horse’s feces. This test is crucial for managing equine health because it helps identify horses with high parasite burdens, allowing for targeted treatment. By knowing the specific parasite load, horse owners can avoid overuse of dewormers, which can lead to resistance.
How is a Fecal Egg Count Conducted?
Conducting a fecal egg count involves collecting a fresh manure sample from the horse, which is then analyzed in a laboratory. The process typically includes:
- Sample Collection: Collect a small, fresh sample of the horse’s manure.
- Laboratory Analysis: The sample is mixed with a flotation solution, and eggs are counted under a microscope.
- Results Interpretation: The number of eggs per gram (EPG) of feces is calculated to assess the parasite burden.
Benefits of Regular Fecal Egg Counts
Regular fecal egg counts offer several benefits:
- Targeted Deworming: Allows for deworming only when necessary, reducing the risk of drug resistance.
- Cost-Effective: Saves money by avoiding unnecessary treatments.
- Improved Horse Health: Ensures horses are treated effectively for parasites, improving overall health and performance.
Understanding Fecal Egg Count Results
What Do Fecal Egg Count Results Mean?
The results of a fecal egg count are expressed as the number of eggs per gram (EPG) of feces. Here’s a general guideline for interpreting these results:
- Low Shedders: Less than 200 EPG – minimal deworming needed.
- Moderate Shedders: 200-500 EPG – may require targeted deworming.
- High Shedders: Over 500 EPG – likely need immediate treatment.
When Should Fecal Egg Counts Be Performed?
Fecal egg counts should be performed several times a year, typically in spring and fall, to monitor changes in parasite loads. This helps in adjusting deworming schedules based on the horse’s needs and environmental factors.
Common Parasites Detected in Fecal Egg Counts
Which Parasites are Commonly Found in Horses?
Fecal egg counts can detect several types of parasites, including:
- Strongyles: The most common equine parasites, causing colic and weight loss.
- Ascarids: Affect mainly young horses, leading to respiratory issues.
- Tapeworms: Can cause colic and digestive disturbances.
How Do Parasites Affect Horse Health?
Parasites can lead to a range of health issues, such as:
- Weight Loss: Due to nutrient absorption interference.
- Colic: Caused by intestinal blockages.
- Poor Coat Condition: Resulting from nutrient deficiencies.
People Also Ask
How Often Should Horses be Dewormed?
Horses should be dewormed based on fecal egg count results rather than a fixed schedule. This targeted approach helps prevent resistance and ensures effective treatment.
Can Fecal Egg Counts Detect All Parasites?
Fecal egg counts primarily detect strongyles and ascarids. Other tests may be needed for parasites like tapeworms, which require specific diagnostics.
What is the Cost of a Fecal Egg Count?
The cost of a fecal egg count varies but typically ranges from $20 to $50 per test. This investment is worthwhile for maintaining horse health and reducing unnecessary treatments.
How Can I Collect a Manure Sample for Testing?
To collect a manure sample, use a clean container to gather fresh feces from the horse’s stall or pasture. Ensure the sample is free from soil or bedding for accurate results.
What are Signs of Parasite Infestation in Horses?
Signs of parasite infestation include weight loss, dull coat, colic, and diarrhea. Regular fecal egg counts help detect infestations before symptoms become severe.
Conclusion
Incorporating regular fecal egg counts into your horse care routine is essential for effective parasite management. By understanding and monitoring your horse’s parasite load, you can implement targeted deworming strategies that protect your horse’s health and prevent drug resistance.
