The main objective of the present study was to determine the prevalence and intensity of gastrointestinal and external parasite infections in goats of North-West of Iran. In spite of the importance of goats in this region, there is no detailed quantitative study on prevalence of goat parasites. Fecal samples were collected from 403 goat for identification of gastrointestinal parasites and presence of external parasites. Seven different species of gastrointestinal parasites including Strongylida, Marshalagia, Nematodirus, Trichuris, Cystocoulus, Monizia and Fasciola, were identified in fecal samples. The number and percentage of infected goats for these parasites were 206 (51.11%) for Strongylida, 37 (9.18%) for Marshalagia, 12 (2.97%) for Nematodirus, 58 (14.39%) for Trichuris, 3 (0.7%) for Cystocoulus, 23 (5.7%) for Monizia and 4 (1%) for Fasciola. The number of eggs ranged from 3 to 172 eggs per gram of feces. A number of 112 samples (27.79%) were positive for Eimeria with oocysts number of 1-390 per gram of feces. It was also found that 12 (3%), 203 (50.4%) and 131 (32.5%) of goats were infested by Sarcoptes scabeii, Damalinia caprae and Ripicephalus bursa, respectively.
