Item Bienestar animal y calidad de carne antes y después del faenamiento en ovinos del Camal Municipal de Ambato(2024-11) Soria Rojas Mónica Abigail; Vargas Burgos Julio CesarThe titled study addresses the relevance of animal welfare and the quality of sheep meat in the context of the Camal Municipal de Ambato, Ecuador. The growing demand for sheep meat and consumer expectations in terms of quality and animal welfare pose significant challenges for the livestock industry in the region. Evaluate animal welfare and sheep meat quality before and after slaughter to identify areas for improvement in handling and transportation practices. An observational and descriptive study was carried out, using a simple random sampling of sheep slaughtered in one month. Parameters such as body condition, live weight, carcass yield. The data were analyzed with SPSS software, applying Student t' tests and analysis of variance. The results indicate that sheep transported from greater distances and in unsuitable vehicles have higher levels of stress, reflected in a greater incidence of DFD (dark, firm and dry) meat. Furthermore, proper management practices, such as the use of effective stunning methods, positively influence meat quality and animal welfare. The study highlights the importance of implementing humane transportation and handling practices to improve animal welfare and the quality of sheep meat in the Ambato Municipal Camal. These improvements not only benefit producers and consumers, but also contribute to the sustainability and competitiveness of sheep production in the region.Item 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 IsmaelIncidence 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.Item Prevalencia de tricomoniasis en bovinos faenados en el centro de Faenamiento Municipal de Pastaza(2024-10) Zúñiga Araujo, Solange Danniela; Carrillo Álvarez, Israel SalomónBovine trichomoniasis is caused by Tritrichomonas foetus, a protozoan species with wide worldwide distribution, causing a sexually transmitted disease in cattle that causes infertility, abortion and endometritis, postcoital pyometra or fetal maceration. In the present study, the prevalence of bovine trichomoniasis in cattle slaughtered at the Pastaza municipal slaughterhouse were determined. A total of 361 samples were taken from cattle admitted to the "Pastaza Municipal Slaughterhouse" from January to April 2024 from the Pastaza, Mera and Santa Clara municipalities. From these data, information on the relationship between the prevalence of the disease and the age, sex and origin of the animal was obtained. The study was carried out through simple random sampling and the data were analyzed using descriptive statistics, frequency and percentages. Additionally, the association of the variables sex, age and place of origin of the cattle with the prevalence of trichomoniasis was established through a Spearman correlation (𝜒 2 ). A general prevalence of trichomoniasis of 2.8% was found in cattle slaughtered in the municipal slaughterhouse of Pastaza, observed only in cattle from five parishes of the Pastaza canton with a total of 10 positive cases. No association was found between the sex, age group and place of origin of the cattle and the prevalence of trichomoniasis in this study. Given the importance of trichomoniasis, it is recommended to carry out studies using molecular biology to confirm the presence of the parasite in herds in the area.
