  1. Instructions on how to use the table: First, check the animal’s condition (poor, OK or good), then check the pasture for “quality/quantity (poor, OK or good).” The value in the cell at the intersection of the animal condition and pasture quality/quantity assessment is the eggs per gram (EPG) threshold for treatment when the coproculture results indicate > 60% of the parasites as Haemonchus or the predominant species is a Trichostrongylus species
