Item 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(2025-02-11) Cuvi Cuenca Keyla Paola; Rodríguez Haro Cecilia ElizabethCurrently, 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.Item Factores de riesgos asociados a la prevalencia de enteroparásitos e histoparásitos en suinos faenados en el camal de Baños de Agua Santa(2024-11) Nasamuez Muñoz Cinthya Dayanara; Núñez Torres Oscar PatricioThe present study focuses on the need to determine the risk factors associated to the prevalence of enteroparasites and histoparasites in pigs slaughtered in the Camal Municipal de Baños de Agua Santa, since the presence of parasites is the cause of various diseases in said animals affecting to the quality of the meat. The post-mortem inspection of the gastrointestinal tract and muscle tissues was carried out in order to evaluate the presence or absence of parasitosis, for which there was a population of 1012 pigs that were slaughtered in the slaughterhouse, then descriptive statistics were used considering the frequency, histograms, using SPSS software. When evaluating the prevalence of parasitic in the present investigation, it was reported that only 173 positive samples were obtained, representing 17.1%, of which the highest prevalence according to sex occurs in males with 59.5%, the prevalence of parasites according to age was occurs in animals. with less than a year is 89%, this implies the lack of deworming during the development and completion stages, this entails economic losses for producers. A higher percentage of parasites was reported in animals from Zaruma (44.5%). According to sex, in the present investigation, a greater presence of Ascaris is seen in males with 56%, this being the main parasite causing economic losses, causing a setback in the development of pigs. According to the risk factors and management that are present in the production systems used determine the prevalence of the parasite load, it is important to consider that the parasites found in this research are of great importance and may even be transmissible. to humans.
