Abstract(s)
The gastric problems in pigs acquired the new expression as intensive practices currently adoptes. The authors document, using macro and microscopic figures, a case of high mortality rate in a sow breeding stock in an indoor farm, aiming to discuss the best resolution to adopt.
A breeding stock with 500 sows and high animal welfare standards, presented outbreaks of sudden death, in 2014 and 2016, that led to nutritional management changes.
Several sows were necropsied and samples fixed in 10% neutral-buffered formalin and processed for routine histopathological diagnosis.
Macroscopic exam, realized during outbreaks, revealed severe gastric ulcers and/or torsions. During the present year, cases of death, due to different etiologies, were necropsied and also showed splenic atrophy, irregularities and thickening at the capsule level. Microscopic exam revealed hypertrophy of smooth muscle of the capsule and splenic trabeculae, with presence of siderocalcary and hemorrhagic nodules.
The authors suggest the diagnosis of postprandial gastric dilatation in animals surviving the outbreaks reported, with severe spleen repercussions that are still observed on the farm.
