“…In a study of 280 pigs, Elbers and others (1995b) observed a prevalence of ulcers of 14·3 per cent but 99·6 per cent of the stomachs showed bile staining of the pars oesophagea; they concluded that there was no causal relationship between the regurgitation of bile and the occurrence of oesophagogastric lesions. The results of this survey indicate that there was a significant relationship between ulceration and bile staining of the pars (P<0·001) (Penny and others 1972, Penny and Hill 1973, R. H. C. Penny and P. A. Mullen unpublished observations), but associations between corrugation, hyperkeratosis and bile in the stomach contents were less clear.…”

In an abattoir survey the stomachs of 1242 pigs from 15 farms were examined. Ulceration of the pars oesophagea was present in 22.95 per cent with a range from 4.7 to 57.4 per cent. The ulcers were graded mild in 9.5 per cent and severe in 13.4 per cent of the stomachs. Bile staining and hyperkeratinisation of the pars were significantly more common in stomachs with ulcers than in those without (P < 0.001), although the difference between the hyperkeratinisation in cases with severe ulcers and cases without ulcers was not significant. The daily liveweight gains of 208 males and 150 females from two units with a high prevalence of ulcers were calculated from their weaning weights at about five weeks of age and their slaughter weights at around 90 kg. At the abattoir their stomachs were examined for the presence of ulcers of the pars. The daily liveweight gain of the males was significantly greater than that of the females (P < 0.001), but the presence of mild or severe ulcers had no influence on the rate of gain of the pigs from either unit. The prevalence of ulcers in the males and females was 57.2 and 49.3 per cent, respectively, but the difference was not significant.

Gastric lesions, especially ulceration, cause significant economic losses in the swine industry worldwide. The study was designed to assess its prevalence, distribution and pattern in pigs in south-western Nigeria. Slaughter house surveys were conducted on three government-established abattoirs in Lagos, Ogun and Oyo states. Stomachs from 480 pigs were assessed for gross lesions, which were graded using a modification of a standard technique. Tissues from different regions of the stomach were routinely stained to assess histopathologic changes. Data were presented as frequency counts and analysed using analysis of variance and chi-square technique. Significance was determined at p ≤ 0.05. Gastric lesions were encountered across the four regions of the stomach with a point prevalence of 57.29%. The prevalence of lesions in the non-glandular region was 32.9%, with severe hyperkeratosis (13.13%) being most frequently observed (p < 0.05). Erosions were significantly higher in the cardia (8.54%) (p < 0.05), followed by fundus (8.33%). Gastric ulcers were significantly higher in the fundus (19.58%) (p < 0.05). Scars of healed ulcers and lacerations were also observed in the fundus (5.42%) (p < 0.05). The gastric lesion distribution across the four regions of the stomach and the occurrence of ulceration in the fundus showed an unusual pattern, which is rarely reported in other parts of the world. The reason for these findings in pigs in Nigeria is not fully understood; therefore, further studies are required to identify and manage these factors for increased productivity, improved animal welfare and enhanced food security.

“…In some herds, mortality due to ulcers can reach 1% or higher, with losses due to culling up to 3% (Nielson 1995). Studies conducted on slaughter pigs revealed that the prevalence of erosions in the pars esophagea of the stomach can be high; for example, 32% (Christensen and Cullinane 1990), 65% (Straw et al 1992), 89% (Elbers et al 1995), 99% (Driesen et al 1987), and 100% (Ito et al 1974). A small dietary particle size has been implicated in an…”

. Effect of feed particle size and dietary melatonin supplementation on gastric ulcers in swine. Can. J. Anim. Sci. 79: 179-185. Gastric ulcers may be an underrecognized problem in the swine industry. An experiment was conducted to evaluate the effects of dietary melatonin supplementation and particle size on prevalence and severity of ulcers in growing pigs. Sixty-four Yorkshire barrows and gilts (29.5 ± 1.0 kg) received either a finely ground (763 ± 2.18 µm) or a coarsely ground (953 ± 2.29 µm) corn-wheat diet, either with or without added melatonin (5 mg kg -1 ). One half of the pigs underwent endoscopic examination to assess the severity of ulcers on days 4 and 25. Growth performance and feed consumption were monitored throughout the experiment. All pigs were slaughtered on day 28, and ulcers were assessed postmortem. Endoscopy at the beginning of the experiment found that 53% of the pigs already had some degree of ulceration. Pigs fed the fine diet had greater average daily gain and average daily feed intake than pigs fed the coarse diet (P < 0.05), but particle size did not significantly affect prevalence of stomach ulcers. Melatonin supplementation increased the apparent digestibility of crude protein (P < 0.04) and dry matter (P < 0.08) of the diets and decreased the prevalence of ulcers (P < 0.05) but did not significantly affect growth performance. Pigs that received melatonin had higher levels of melatonin (P < 0.01) in most gastrointestinal tissues, with highest concentrations found in the stomach (P < 0.001). Pigs that did not have ulcers had a higher concentration of melatonin in the plasma and stomach than pigs with ulcers (P < 0.05). Melatonin may be useful in decreasing ulcers. Initial ulcer condition may be a significant source of variation in growth experiments.Key words: Pigs, gastric ulcers, particle size, melatonin, gastrointestinal tract Ayles, H. L., Friendship, R.

Sci. 79: 179-185. Les ulcères gastriques pourraient bien être un problème trop peu connu dans le secteur porcin. Nous avons réalisé une expérience pour évaluer les effets d'un complément de mélatonine dans l'alimentation et du calibre des particules alimentaires sur la fréquence et sur la gravité des ulcères chez les porcs en croissance. Soixante-quatre porcs Yorkshire, castrats et cochettes, d'un poids moyen de 29,5 kg (± 1,0 kg) ont reçu un aliment maïs-blé, moulu fin (763 ± 2,18 µm) ou gros (953 ± 2,29 µm) et complété ou non de mélatonine à la dose de 5 mg kg -1 . La moitié des animaux subissaient un examen endoscopique pour évaluer la gravité des ulcères au jour 4 et au jour 25 de l'expérience. Les performances de croissance et la consommation alimentaire étaient surveillées en permanence. Tous les porcs étaient abattus au jour 28, après quoi on évaluait la gravité des ulcères. L'endoscopie faite au début de l'expérience a révélé ...
