The goal is to keep parasite reproduction and environmental contamination in check, in order to cut down on the number of larvae available to infect – and re-infect – our horses.

Deworming is just one factor in the success of your strategic parasite management program.

Just as important is preventing contamination between deworming treatments, through sound horse and pasture management practices.

Below are a few key measures that you can take to help reduce the spread of infection and the need for chemical deworming. 

  • Perform a fecal count reduction test on all new arrivals, before releasing them into the herd.
  • Avoid pasture contamination from heavy shedders by keeping them together (and apart from horses with a lower worm burden), as much as possible.
  • Avoid high stocking density in pastures.
  • If adequate grazing is available, rotate pastures.
  • Avoid ground feeding, in order to minimize the potential ingestion of worm eggs and larvae.
  • Do not spread fresh manure on land.
  • Do not chain harrow paddocks unless they will be unoccupied for one month, and the temperature is hot and dry enough to desiccate parasite eggs.
  • Remove manure piles, if possible.
