First Year:

  1. 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
  2. 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
  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
