Causes of death in growing-finishing pigs in two technified farms in southern Brazil

Abstract: The aim of this study was to investigate the main causes of death in growing-finishing pigs in southern Brazil. During a one-year period (from 2018 to 2019), two industrial pig herds (18 and 20 thousand pigs each farm) in southern Brazil were monitored along the four seasons of the year (12 days per season on each farm), in order to perform necropsies of all pigs that died in that period. The two farms had an average monthly mortality rate ranging from 0.94 to 3.93% in the evaluated months. At necropsy, tissue… Show more

“…to necropsy (Piva et al 2020). In our study, the clinical and pathological presentation of this disease agreed with the descriptions in the available literature, with gastric ulcers being incriminated as the cause of sudden death and even as a chronic and cachetizing condition (Friendship 2004, Thomson & Friendship 2012.…”

“…Infectious diseases represented infrequent causes of death of sows in this study. In other studies carried out in Brazil, infectious diseases were responsible for the majority of deaths of weaned and growing-to-finishing pigs (Brum et al 2013, Piva et al 2020, and were also very common in sows (Vearick et al 2008). In the study of Vearick et al (2008) the genitourinary infections were the most frequent cause of death of sows, with 30.8% of the diagnosis.…”

“…Gastric or splenic torsion has occasionally been reported as a cause of sudden death in swine (Piva et al, 2020), as stomach and spleen infarction and congestion can occur, due to the occlusion of the vessels involved in the irrigation and drainage of these organs (McGavin & Zachart, 2009). If one of these torsions occur in collared peccaries, the structural arrangement of the celiac artery would not reduce the degree of organ involvement when compared with the patterns observed in domestic swine or other mammals, given that rotation causes blood obliteration mainly in the vascular stomach and spleen pedicles (Ortiz et al, 2016).…”

“…However, since the circulatory and respiratory systems seem to play important roles for sudden deaths, both among finishers 6 , 12 and sows 8 , 13 , one strategy could be to develop indicator traits, e.g. quantifying the capacity of the heart and lungs.…”
