Table 3.

Fecal egg count/coproculture results: guidelines for flock treatment

Animal condition	Pasture quality/quantity
	Poor	OK	Good
Barber’s pole worm (Haemonchus contortus) > 60% of culture
Poor	600	800	1000
OK	800	1000	1100
Good	1000	1100	1200
Scour worms (Trichostrongylus spp.)
Poor	300	400	500
OK	400	500	600
Good	500	600	700

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
