Abstract Visits were made to six farms raising dairy goats located in the mountain region of the state of Rio de Janeiro, Brazil, seeking to identify parasitism by Giardia sp. and Cryptosporidium sp. During the visits, fecal samples were collected from approximately 10\% of the stock of each property. A questionnaire was given to the keepers on each property to obtain data for epidemiological analysis. A total of 105 fecal samples was collected, 56 from adult animals (over 12 months of age) and 49 from juvenile animals (less than 12 months). The fecal material was processed and subjected to the centrifuge-flotation technique and to staining with safranine-methylene blue. Protozoans of the genus Cryptosporidium were found at two properties, where the hygiene conditions of the installations were considered average and the stalls were made of wood slats raised from the ground. A total of five (4.8\%) of the samples was found to be positive for the presence of this protozoan, all from juvenile animals. Cysts of the genus Giardia were found at two properties. Of the 105 samples analyzed, the protozoan was detected in 15 (14.3\%), all in juvenile animals, and animals in the age range of 1-3 months had significantly more infections. Age, sanitary condition of the stalls and stalls made of wood slats and raised from the ground, can be pointed out as possible risk factors for infection by Giardia sp. and Cryptosporidium sp. The study reports for the first time the occurrence of Cryptosporidium sp. and Giardia sp. in goats in the state of Rio de Janeiro.
