Only severe gastric ulcers reduce performance in growing-finishing pigs

Ulceration in the pars oesophageal region of the stomach of pigs is frequently registered at slaughter. Pigs with gastric lesions are reported to have lowered productivity (Ayles et al., 1996), but other studies have found no significant effects on performance (Guise et al., 1997). The objective of this study was to quantify the correlation between ulcer severity and growth performance in growing-finishing pigs

Performance and gastric ulcers in growing-finishing pigs fed alfalfa hay meal or a coarse-milled pelleted diet

Danish producers using pelleted feed and experiencing problems with gastric ulcers in their herd are sometimes advised to use diets containing alfalfa hay meal or diets that have greater mean particle size. However the effects of such interventions have not fully been investigated. These experiments investigated the effect of alfalfa hay meal and coarser milling in pelleted diets on growth performance and occurrence of gastric ulcers in growing-finishing pigs
