    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 Cesar
    The 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.

    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.

    Prevalencia de Fasciola hepática en bovinos faenados en el Camal municipal del Cantón Pelileo Provincia de Tungurahua en el período Marzo-Mayo del 2024
    (2024-11) Carranza Arévalo Álvaro Iván; Almeida Secaira Roberto Ismael
    Fasciolosis is a zoonotic disease caused by Fasciola hepatica, which is considered a tropical disease that threatens the productivity of ruminants due to the economic losses associated with the presence of the parasite. The prevalence of Fasciola hepatica in cattle slaughtered at the municipal slaughterhouse of the Pelileo Canton, Tungurahua Province, was evaluated in the period March-May 2024. The study was carried out through macroscopic observation of livers obtained from cattle slaughtered at the slaughterhouse and the possible association between the sex and origin of the animal on the predisposition to the presence of the parasite was evaluated using a Pearson association test (𝜒2). From a total of 1,622 animals sampled, the overall prevalence of Fasciola hepatica in the dataset was found to be 8.08%, which corresponds to 131 animals that presented symptoms of the disease. In relation to the place of origin, the highest prevalence was observed in cattle from Salcedo, Chiquicha parish, Ambato and El Rosario with values of 9.9%, 9.8%, 9.7% and 9.6%, respectively, which are considered moderate values, while in Bolívar, the prevalence was the lowest (4.5%). No association was found between sex and prevalence, with percentages of 43.9% in males and 45.3% in females (𝜒2=0.243). The total value in liver losses, considering the price per kilo and the number of positive animals for each group was $2,728.00 during the study period, making a ratio of 100% of slaughtered livers (1,622 units), a loss of 8.08% due to confiscations is obtained. Given the prevalence of the parasite in livestock in the production areas of the Sierra zone, the development and implementation of training programs for small and medium producers on the management of F. hepatica in their production units is recommended.
