Individualized Strategic Deworming Program
First Year:
- Perform Fecal Egg Count 8 weeks after the last dewormer (12 weeks if moxidectin)
a. Assigned equine to categories based on quantitative FEC
i. Low Shedder <200 eggs/gram of feces
ii. Medium Shedder 200-500 eggs/gram of feces
iii. High Shedder >500 eggs/gram of feces
- Perform another FEC 2 weeks after proper administration of the dewormer to determine resistance
a. Deworming should result in >90% reduction in egg counts
b. If not reduced to proper counts, deworm with another product and retest in 2 weeks
- Perform FEC before and 2 weeks after all new dewormers to determine resistance patterns
Subsequent Years:
- Perform twice yearly FEC to monitor parasite control

Foals and horses up to 3 years of age:
- Starting at 60 days of age we recommend rotating dewormers at 8 week interval
a. Start with either fenbendazole or pyrantel followed with ivermectin alternating every other 8 weeks until 3 years of age
Horses that are new or returning to a farm:
- Ivermectin + Praziquantel when introduced to the farm
- Perform a FEC 8 week's post dewormer and enroll in program
a. If eggs are present begin a Panacur Power Pack
b. Recheck FEC 2 weeks after Panacur Power Pack
