SALDIVIA PAREDES, M. A. et al. Diagnosis of gastrointestinal parasitosis in beef cattle of butcher breeds with different coproparasitological techniques. Rev. Med. Vet. Zoot. [online]. 2022, vol.69, n.3, pp.259-267.  Epub 12-Jan-2023. ISSN 0120-2952.  https://doi.org/10.15446/rfmvz.v69n3.103806.

Gastrointestinal parasites in production cattle are one of the most important health problems worldwide. These nematodes cause gastroenteric problems that are clinically characterized by diarrhoea, weakness, bleeding and dehydration. Within the gastrointestinal parasites caused by nematodes in cattle, the following families stand out: Trichuridae, Trichostrongylidae, Ancylostomidae, Ascaridae and Strongyloididae. The purpose of this research was to determine the efficacy of the different qualitative and quantitative coproparasitological techniques for the detection of gastrointestinal nematodes in cattle. For this study, 250 samples of beef breed cows were used, divided into different groups, for the application of qualitative and quantitative coproparasitological techniques, which were specifically chosen taking into account inclusion and exclusion criteria for each animal. The results delivered by this study indicated that the highest percentage in the identification of parasitic infective states was through qualitative coproparasitological techniques, focused mainly on zinc and magnesium sulfate flotation techniques with 50%.
