Fecal Egg Count Testing
Modified McMaster FEC — Results in Eggs Per Gram (EPG)
A fecal egg count measures the parasite egg load in a fresh manure sample, giving you and your veterinarian a clear, objective basis for deworming decisions — treating only the animals that need it and slowing parasite resistance.

Targeted deworming protects your animals, your budget, and the long-term effectiveness of the treatments you rely on.
Fresh Manure Sample
About the size of a large chicken egg per animal.
Modified McMaster
Proven counting method for reliable, repeatable results.
Eggs Per Gram
Reported as EPG with a clear low, moderate, or high shedding level.
Fast Turnaround
Results reported promptly so you can act while they matter.
