Topographic distribution of gastritis in heavy pigs investigated by a geographic information system approach

Abstract

The aim of this paper was to determine the topographic distribution of gastritis lesions in pigs through an open source geographic information system (GIS) software analysis. The stomachs of 146 Italian heavy pigs were collected at slaughter and subjected to macroscopic pathological examination of the internal mucosa. A total of 623 lesions were either classified as hyperplastic or follicular (97%) with the remaining minority of lesions categorised as atrophic and simple. The hyperplastic gastritis lesions had an average surface of 77.8 cm2 and were mainly located in an oval shaped area of the fundus region of the stomach near the Curvatura ventriculi major. The follicular gastritis lesions had generally a smaller surface (40.3 cm2) and were concentrated in two distinct small areas of the pyloric region. The GIS analysis provided the opportunity to produce useful maps showing the distribution and characteristics of gastritis in pigs.

Distribution patterns of saprolegniosis cutaneous lesions in wild and farmed brown trout (Salmo trutta L.) obtained using a geographic information system (GIS)

“…It has been confirmed that GISs can successfully be used for topographic analyses of animal diseases, to create maps of lesion type and distribution on the animal's body. GISs have previously been used to study spinal disc herniation in dogs (Daraban et al, 2014), nodular skin lesions and their malignancy in dogs (Pascotto, Tomè, Comazzi, Marco, & Cornegliani, 2014), gastric lesions in pigs (Pascotto, Capraro, Tomè, & Spanghero, 2016) and the corporal distribution of Ctenocephalides felis felis and C. canis fleas in dogs (Rinaldi et al, 2007).…”

Digestibility, metabolic utilisation and effects on growth and slaughter traits of diets containing whole plant maize silage in heavy pigs

“…The repletion of the stomach with coarse material has an impact on the incidence of the damages of the stomach mucosa and the hyperplastic and the follicular gastritis are the more frequent lesions in heavy pigs with a prevalent localisation in the fundic and pyloric areas (Pascotto et al 2016). In the present trial, we observed a tendency to increase the hyperplastic gastritis in pigs fed the CS diet and this could be interpreted as a reaction of the mucosa to the presence of coarse materials in the gastric contents.…”
