    Abstract:
    The objectives of the present study were to evaluate the prevalence of gastrintestinal helminthosis of calves and to identify control aspects related to these infections in dairy farms of the municipality of Alegre, Espírito Santo. A total of 222 calves varying of one to 18 months of age were examined and proportionally divided between 12 dairy farms. After techniques in the laboratory of parasitic diseases of the veterinary hospital of Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, the prevalence of eggs of Strongyloidea, Trichuris sp., Moniezia sp, Strongyloides papillosus and coccidial oocysts were, in properties and calves: 100 and 66; 100 and 57.8; 50 and 8.2; 25 and 1.8, and 33.3 and 7.8%, respectivelly. Of the 66 for eggs of the Strongyloidea, 64 were attributed to Haemonchus spp. and 53.75% to Cooperia spp. Despite the existence of parasite control programs in the farms, were identify some wrong practices, as lack of weighting animals for the calculation of the dose rate of the drugs and lack of use of the compost of excrements. Thus, the drugs uses of incorrect form may be able to cause future damages with development of parasites resistance to these products.
