Gastrointestinal nematode infection in ewes raised in an arid zone of Venezuela

The necropsy of a total 72 ewes coming from the Venezuelan arid zone (State of Falcón) was carried out as follow: 6 ewes per month; 30 during rainfall period and 42 during the dry period. The following nematode species were identified: Haemonchus contortus, Trichostrongylus axei, T. colubriformis, C...
