rThis test uses a special microscope slide with a grid which
makes counting easier. Manure and flotation fluid is
measured and mixed and only a small portion of the total
mixture is counted. A calculation is performed to determine
the number of eggs/gram in the manure. The counting
techniques for ruminants are designed to count strongylids or
gastrointestinal nematode worms including the barber pole
worm (H. contortus), but can be used for other parasites as
well.
