For more about the Fecal Egg Count and Deworming, please visit our Parasites & Deworming page.
The dewormers used in foals (Anthelcide, Strongid, and Panacur) do not kill the larval stages of roundworms. They only kill the adult roundworms in the gastrointestinal tract, which will not be present until 8-12 weeks of age.
60 days: Anthelcide or Strongid
90 days: Fecal egg count to check Parascaris levels
120 days: Anthelcide or Strongid
150 days: Fecal egg count
180 days: Strongid
240 days: Quest
300 days: Anthelcide
The FECRT is only for a specific dewormer (ex. Quest) and must be repeated if another medication is used to check for resistance.
