[The relationship between larvae recovered of pasture and counting eggs per grams of feces (epg) of the gastrointestinal nematodes of cattle in the Microrregion of Viçosa, State of Minas Gerais].

Eight calves with one year old approximately, Holstein-zebu cross-breeding, were stocked in paddock to analysis the relation between the eggs per grams of feces (EPG) and larvae number recovered of pastures, from February to September 2005, at municipality of Viçosa, Zona da Mata region, State of Minas Gerais, Brazil. During this time, feces and pastures were collected for examination of EPG and larvae recovered from pastures, respectively. The genera Cooperia, Haemonchus and Oesophagostomum larvae were harvested in paddock until 20 centimeters and between 20 and 40 cm far distance of fecal cake. The genus Cooperia (60.97%) was the most prevalent in the pastures. In coprocultures, Haemonchus (42.65%) was the most prevalent genus of nematode. The coefficient of correlation of the larvae recovered of pasture and the EPG was not significant (P < 0.05). It can indicate that this relation can be influenced possibly by several factors related on the nematodes, the host and the climate conditions.
