Abstract
In swine production, parasites, especially gastrointestinal helminths, generate considerable economic losses. Therefore, effective control measures, such as the use of the correct anthelmintics, are of paramount importance for maintaining profitability. The aim of the present study was to evaluate the efficacy of the anthelmintic oxibendazole, administered orally, in pigs (non-industrial) naturally infected with gastrointestinal nematodes. To that end, we selected 18 pigs naturally parasitized by gastrointestinal nematodes, as determined by examination of fecal samples (eggs per gram (EPG > 500) of feces), and divided them into two groups: treated (with a 10-day course of oxibendazole) and control (untreated). After the treatment period, the animals were euthanized. During necropsy, the helminths in the gastrointestinal tract were identified and quantified. The species identified were, in order of occurrence, Ascaris suum, Trichuris suis, Oesophagostomum dentatum, and Hyostrongylus rubidus. In Brazilian swine herds, traditional (non-industrial) production systems can favor the transmission of helminths. We found that treatment with oxibendazole was 100% effective against A. suum and H. rubidus, whereas it was 99.65% effective against O. dentatum and 99.20% effective against T. suis, significantly reducing helminth counts (P < 0.01 for all). We conclude that oxibendazole is effective in controlling the main helminths in swine.
Highlights
A presença de parasitoses na suinocultura gera prejuízos econômicos relevantes
Losses in productivity are recurrent problems that are linked to the presence of parasites and other diseases in the herd, which must be rigorously studied so that producers can develop effective control measures (Lopes et al, 2014)
On the basis of the above, the aim of the present study was to evaluate the anthelmintic efficacy of oral oxibendazole against gastrointestinal nematodes in naturally infected pigs, as well as to describe the occurrence of helminths in the region surrounding the city of Franca, Brazil
Summary
A presença de parasitoses na suinocultura gera prejuízos econômicos relevantes. Dentre elas, destacam-se as helmintoses gastrintestinais. There have been few studies of the occurrence of intestinal parasite infection or of the use and efficacy of anthelmintic drugs in pigs in Brazil, and most such studies have not been up to date.
