Diagnóstico de la prevalencia endoparasitaria en ovinos de pelo de la quinta alicia, parroquia Veracruz, Pastaza

Abstract

Internal parasitosis is one of the main problems faced by sheep farmers due to the lack of knowledge of the correct control and treatment of parasites. Therefore, the objective of this research was to diagnose the prevalence of endoparasites in hair sheep of Quinta Alicia, one of the most important sheep productions in the Amazon region. The methodology implemented had a qualitative and quantitative criterion, the study population consisted of 80 sheep of different categories, being essential the bibliographic research and field work to collect the respective information through laboratory techniques. By means of this methodology, it was possible to determine that the endoparasite prevalence in the sheep of Quinta Alicia is 98.75% of the total number of animals, with Eimeria sp, the endoparasite with the greatest presence in the flock, with a prevalence of 90%, followed by Moniezia expansa with 67.5% and Nematodirus with a lower incidence of 2.5%. The parasitic load analyzed indicates that sheep <3 months of age are the group with the highest load, being 657.02 hpg, followed by sheep 3-8 months of age with a load of 434.62 hpg and sheep >8 months of age with a load of 288.88 hpg. The control of these parasitic loads has been managed with routine dewormers, demonstrating that the coccidiostat Tolprox 5%, has an efficacy of 98%, antiparasitic Prosantel 10%, efficacy of 88.09% and FAVECAN with 76.2%. According to the results, it is concluded that, due to the limited management and disinfection of paddocks, there is a high prevalence of endoparasites in the herd, so it is recommended to carry out a planned rotation of paddocks, as well as a disinfection calendar that allows cutting the cycle of parasites in the pasture.
