The aim of this study was to determine the prevalence and monthly parasitic load of gastrointestinal nematodes and Fasciola hepatica in dairy cattle of the districts Nueve de Julio and Matahuasi el Mantaro Valley (Junín, Peru), as well as the epidemiological factors associated with these parasitosis. Monthly faecal samples were collected from 11 dairy farms in each district for one year. The samples were analysed with the modified Dennis technique for the detection and counting of F. hepatica eggs and the modified McMaster technique for nematode eggs. The mixed logistic regression test was used to evaluate the variables district, time of year, feeding system, age, temperature, rainfall and humidity as possible risk factors. The average monthly prevalence in Matahuasi and Nine of July for gastrointestinal nematodes was 24.5 and 30.3%, with monthly loads of 118.3 and 87.4 hpg, and for F. ...
