Lesões gástricas em equinos de abatedouro: avaliação macroscópica e histológica

The aim of this study was to evaluate the frequency of lesions in different regions of stomach of asymptomatic horses. Stomachs were evaluated macroscopically, which identified the nature of lesions. Subsequently, fragments were obtained from five regions previously mapped for histological examination, as well as from other areas with lesions. From a total of 21 animals, only one had isolated macroscopic lesion in glandular region, six in nonglandular region and 13 showed lesions in both regions. One animal showed no macroscopic lesion. Histologically, the most frequent lesions were gastritis (19/21), ulcers (14/21) and erosion (8/21). Most cases were acute ulcer and erosion, and gastritis chronic. The results of this study show the high frequency of lesions in the stomach of apparently healthy slaughter horses.
