An evaluation of the use of a flexible videoscope to efficiently monitor ulcers of the pars oesophagea was carried out in grower-finisher pigs. Gastroscopy was performed on 2 separate occasions in 32 pigs following anaesthesia with intravenous pentobarbital. Ulcers of the pars oesophagea were subjec...

The effects of dietary particle size on the prevalence and severity of gastric ulcers were examined in 80, individually housed Yorkshire pigs (24.1±2.9 kg) fed ad libitum on finely ground (particle size 578±1.89 μm), maize-wheat diet for 2 weeks. All pigs were examined endoscopically, and ulcers ...

64 Yorkshire barrows and gilts (29.5 kg liveweight) received a finely-ground (763 µm) or a coarsely-ground (953 µm) corn [maize]-wheat diet, with or without added melatonin (5 mg/kg). One half of the pigs underwent endoscopic examination to assess the severity of stomach ulcers on days 4 and 25. G...

Four weeks of administration of melatonin mixed in the diet (5 mg/kg of food) significantly reduced the incidence of gastric ulcers in young pigs. In control and melatonin supplemented animals, significantly higher levels of melatonin were found in the stomach tissues as compared to jejunum, ileum, ...

To induce gastric ulcers, finely ground (578±1.89 µm), maize-wheat-based diets containing melatonin 0, 2.5, 5 and 10 mg/kg, were offered to 64 Yorkshire barrows and gilts (mean weight 22.2±2.0 kg) assigned to 16 pens (4 per pen), until they reached 105 kg. At postmortem, ulcers were scored from 0...
