Strategic Deworming Program:
First Year:
1. Performed 8 weeks (12 weeks if moxidectin) after the last dewormer
a. Assigned to categories based on quantitative Fecal Egg Count (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
2. Performed 2 weeks after proper administration of the dewormer to determine resistance
a. >90% reduction in egg counts
b. If not reduced to proper counts, deworm with another product and retest in 2 weeks
3. Perform FEC before and 2 weeks after all new dewormers to determine resistance patterns
Subsequent Years:
1. Perform twice yearly FEC to monitor parasite control

Foals and horses up to 3 years of age:
1. Starting at 60 days of age we recommend rotating dewormers at 8 week interval
a. Start with fenbendazole/pyrantel followed with ivermectin alternating every other 8 weeks until 3 years of age
Horses that are new or returning to a farm:
1. Ivermectin + Praziquantel when introduced to the farm
2. 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
