Fecal Egg Counts: Not Just a lot of “Poo”
Parasite prevention is important. Internal parasites can cause severe colic, diarrhea, and general unthriftiness. Resistance to our current dewormers is becoming more common, therefore, owners and veterinarians need to be proactive in preventing resistance and doing what is best for our horses. A combination of pasture management and a fecal egg count program is the best method.
In the south, parasite eggs on pasture are at their peak from September through April.
Pasture management strategies:
The new recommendation is to deworm based off fecal egg counts rather than an every other month rotation. FEC’s are useful to determine:
All horses should be dewormed in the late fall with a product that kills tapeworms and bots as these rarely show up on our standard McMasters test. We have also added discounted fecal egg counts to our equine wellness program as a benefit to those on the program.
Fresh manure samples (about a handful amount) should be placed in a sealed plastic bag and should not be more than two hours old. They should then be refrigerated as soon as possible. Please label them with your horse’s name, your name, and the date. They are fine refrigerated for a couple days, but plan the collection at a time that is convenient for delivery to us within a day or two.
