| Summary: | ABSTRACT: This study evaluated the prevalence of swine carcass condemnation due to respiratory diseases at slaughter, and its association with climatic and farm-related risk factors. This study comprised a retrospective analysis of data from 156 pig growing-and-finishing farms for a period classified into years 1 (October2016 to September2017) and 2 (October2017 to September2018). These periods were then further divided into dry and rainy seasons. The impact of risk factors on carcass condemnation, such as farm production rates, was also analyzed. Swine carcass condemnations was higher during the dry seasons, with wet pleuritis accounting for 60.38% of all condemnations (P < 0.0001). In addition, carcass condemnation was higher in year 2 than in year 1 (P < 0.0001). Carcasses condemned for dry pleuritis were released for consumption, while those condemned for pleuropneumonia were redirected to grease production (P < 0.0001). Lots with piglets from two or more origins compared with a single origin, as well as a shorter cleaning and disinfection (C&D) plan, accounted for a higher prevalence of condemned carcasses. Climatic conditions, number of piglet origins, and C&D plans are associated with higher condemnation prevalence rates due to respiratory diseases in the abattoir. |
