MONITORING OF THE INTESTINAL TRACT PARASITE LOAD AND OF THE SANITARY MANGEMENT AT A PACA BREEDING FARM

Abstract

Paca (Cuniculus paca Linnaeus, 1766) rearing has shown development in all Latin America countries. Fresh feces samples were collected from the soil and analyzed by Willis Mollay and Hoffmann’s techniques, aiming at accompanying the sanitary management, determining the prevalence of gastrointestinal parasites, and their respective load, of pacas raised in captivity, and evaluating parasite control strategies, between the months of November/2012 and June/2013. A McMaster’s camera was used for quantification. The reading was accomplished by optical microscopy with 25x and 40x lenses, which revealed 21,433 eggs per gram of feces (EPG), with an average of 2,679,12 (± 41.0) Strongyloides spp., and 3,325 EPG, with average of 415.6 (± 57.0) Trychuris spp. Besides, 482,101 oocytes per gram of feces (OPG) were found, with an average of 60,263 (± 15.93) Eimeria spp., and 51 larvae of Strongyloides spp., with an average of 6.3 (± 6.86) larvae. Two eggs of Hymenolepis diminuta were identified in only one stall. An anthelminthic (albendazole 10%) and trimethopim associated with sulfadiazine were used to treat the disease. We concluded the great index of parasitic infestation presented by the animals, in spite of the anthelminthic treatments, can be associated with the rainfall rates observed, the physical conditions of the instalations, as well as the adequate cleaning and sanitization of the facilities.
