Identificación de los factores de riesgo asociados a enteroparásitos en gallinas criollas (Gallus gallus domesticus) de traspatio en las zonas rurales de la parroquia San José, de la provincia de Pastaza, Ecuador

Abstract

Currently, there are not enough formal studies on parasitological fauna in backyard birds in Ecuador, for this reason the present work aims to contribute with knowledge regarding the prevalence and parasitic incidence of backyard poultry production in parish San José, province of Pastaza, likewise, describe the importance of sustainable and sustainable production that guarantees food safety because to strengthen both animal health and the sanitary management of animals by identifying risk factors to prevent them through sanitary control management, therefore, the objective of the present investigation was to identify the main gastrointestinal parasites associated with risk factors and zoonotic interest in backyard birds from rural areas of the tropics. Fecal samples were collected from 80 birds (roosters and hens) of different ages under a backyard breeding system. The samples were collected at random. For laboratory analysis, the samples were subjected to flotation and washing tests and the Mc Master technique. The prevalence of parasites could be determined with a value of 91.25%, depending on sex, the positive parasite prevalence in females was high (60%). Regarding the identification of parasites, the prevalence of: Hymenolepis setigera and Capillaria spp was reported with 27% respectively, followed by Eimeria spp (26,3%). Depending on age; The parasite prevalence was higher in birds older than 12 months. Finally, the Odds Ratio values were greater than 1, in factors such as deworming, feeding, and housing, which is considered a viable irrigation factor, favoring parasite infestation.
