Abstract

OLIVEIRA, A.S Economic loss resulting from the condemnation of bovine intestines slaughtered in Santarém, Pará, Brazil. 2023. f. Dissertation (Master's) - Faculty of Veterinary Medicine and Animal Science, Federal University of Mato Grosso do Sul, Campo Grande, MS, 2023.

The present study aimed to evaluate the main causes of condemnation of bovine intestines and their economic losses. This study was carried out through a six-year retrospective data analysis (January 2015 to December 2020), considering the bovine species, from a refrigerated slaughterhouse under the Federal Official Inspection service, located in the Municipality of Santarém, Pará, Brazil. For this, the condemnation information was obtained through monthly reports, considering the number of slaughtered animals, number of condemned organs and main injuries that led to condemnation. The intestines (small and large) were condemned for the causes observed in this study, with only the major causes of condemnation being pointed out: contamination, tuberculosis, enteritis and verminosis. To calculate the representation of each cause of conviction, the total number of intestines condemned over the total number of each cause was considered. To estimate the economic damage caused by the condemnation of the intestine, the weight of this organ was used. The economic loss was also determined and the prediction of losses was carried out. Evaluating the isolated frequencies of diseases, significant differences were found with higher frequencies of worms, followed by contaminations and the lowest frequency referring to the cause of tuberculosis. In relation to economic losses, verminosis was the disease that presented the highest index, followed by contamination. Thus, it was possible to observe considerable economic loss in the condemnation of the intestine over the years, mainly caused by verminosis.
