    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 Patricio
    The 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.

    Factores de riesgo asociados a enfermedades causadas por nematodos y cestodos endoparásitos en cerdos en el Centro de Faenamiento Pelileo
    (2024-10) Lascano Gualpa, Rosa Obdulia; Almeida Secaira, Roberto Ismael
    Incidence of internal parasites affects pig production, which not only causes significant economic losses in livestock production worldwide, but also implies a risk to the health of people involved in this type of industry and consumers of meat. of pork. Thus, the present study was carried out in order to analyze the risk factors associated with diseases caused by endoparasite nematodes and cestodes in pigs at the Pelileo Slaughter Center during the period 2023-2024. Diagnosis of parasite species was carried out following the procedures established by the Ministry of Agriculture, Livestock, Agriculture and Fisheries with its attached entity AGROCALIDAD (Agency for Phyto and Zoosanitary Regulation and Control). The species were found: Ascaris sp. and Hyostrongylus sp. (Nematoda) and larval phase of Cisticercus tenuicollis and the hydatidic cyst (Cestoda) mainly associated with the liver of pigs. The highest prevalence was observed for Ascaris sp. infections (21.07%) followed by larvae of Echinococcus granulosus (19.73%) and Hyostrongylus sp. (5.87%), while double Ascaris-Hyostrongylus infections were relatively low (1.33%) as well as infections by hydatidic cysts (1.07%). Regarding risk factors, it was found that age was associated with the prevalence of parasites, being higher in pigs less than 1 year old. Regarding the location within the host, parasites were mainly found in organs that make up part of its biological cycle. On the other hand, no association was found with the sex of the host. According to the results, the prevalence of Ascaris and metacestods of Echinococcus seems to be related to herd management factors, however, this aspect requires investigation.
