RESUMO:

The objective of this study was to investigate the prevalence of swine carcass condemnations for respiratory diseases at slaughter and to associate the impact of climatic risk factors and factors related to farms. The work comprised a retrospective study of 156 swine growth and finishing properties integrated to an agro-industry in the southwest of Goiás State from October 2016 to September 2018. The work period was divided into year 1 (October / 2016 to September / 2017) and year 2 (October / 2017 to September / 2018), as well as the weather conditions were divided into two seasons, dry season (from April to September) and rainy season (from October to March). To analyze the impact of risk factors on convictions, the climate variable was selected according to the dry or rainy season and the factors directly related to the farms: sanitary void (interval between lots) and number of origins distributed in 1; 2-3; 4-5 and over 6 origins. The results of zootechnical indices such as housing weight (Kg), slaughter weight (Kg), daily weight gain (Kg), mortality and feed conversion were also evaluated. For statistical analysis, the SAS® Software v.s. 9.5. was applied with a significance level of 5%. Swine carcass condemnations were found to be higher during dry seasons (P<0.0001), with wet pleuritis accounting for 60.38% of the condemnations. Carcass condemnations were higher in year 2 (P<0.0001) compared to year 1, with wet pleuritis with 74.92% and pneumonia 61.96%. A total of 99.51% of carcass condemned for dry pleuritis were released for consumption, for wet pleuritis or pneumonia, 99.65% and 99.58%, respectively, were for cooked products and 99.51% of carcasses condemneds for pleuropneumonia were intended for grease (P <0.0001). According to the origin of the piglets, the lots from two or more origins obtained higher number of condemned carcasses (P <0.0001) in relation to the single origin farms. Thus, it was observed that the risk factors related to the climatic condition and the number of piglet origins are associated with the prevalence rates of slaughter carcass condemnation.
