Determinación de la prevalencia de parásitos (Helmintos) en bovinos faenados en el camal de la parroquia urbana Macas, cantón Morona.

Abstract

The objective of this research was to determine the prevalence of helminth parasites in cattle slaughtered in the feedlot of the urban parish of Macas, Morona canton. The fecal sample collection process was carried out directly from the rectum of the cattle before slaughter. The Willis Molloy saline flotation method and the simple sedimentation technique were used in the laboratory. The dependent variable analyzed was the prevalence of helminth parasite eggs by gender and species, while the independent variables analyzed were the sex and age of the cattle. Since this is discrete information, the frequencies obtained were analyzed with the Chi-square statistic at a probability of less than 0.05 and the prevalence was calculated by the number of hosts infected by a particular parasite species, divided by the number of total hosts examined. The following results were obtained: higher parasitic load in females with 53 positive cases and 35 in males as well as in animals among the age of 24, 36 and 48 months, the helminth parasites with higher prevalence belong to the nematode type were Cooperia spp with 5.43 %, followed by Ostertogia spp with 4.35 %, and Oesophagostomun radiatum with 3.80%, while in the case of trematodes the species Fasciola hepatica was reported with higher frequency at 2.72%. It was concluded that there is a higher prevalence of nematodes of the genus Cooperia spp, Ostertogia spp and Oesophagostomun radiatum and trematodes of the species Fasciola hepatica. Improved sanitary controls and deworming with carbonate benzimidazoles (albendazole) in combination with biosynthetic avermectins (doramectin) are recommended.
