“…The presence of straw bedding was associated with a significant reduction in the average severity of the gastric ulcers observed, in agreement with the findings of previous studies in which straw bedding has been associated with a lower inci-dence of stomach ulcers than fully slatted floors (Guy and others 2002); and straw has also been reported to ameliorate the ulcerogenic effects of feeding a finely ground diet (Nielsen and Ingvartsen 2000). It is also possible that on the farms in the present study, the straw provided a source of environmental enrichment, which has been shown to improve the ability of pigs to cope with environmental stressors (Pearce and others 1989).…”

“…It is also possible that on the farms in the present study, the straw provided a source of environmental enrichment, which has been shown to improve the ability of pigs to cope with environmental stressors (Pearce and others 1989). However, the dietary effects of straw may be of greater importance in reducing the likelihood of the development of stomach ulcers (Nielsen and Ingvartsen 2000). The addition of crude fibre in the form of either oat husks or sunflower hulls to finely ground diets has been reported to reduce the development of gastric lesions (Potkins andothers 1989, Dirkzwager andothers 1998).…”

Factors in the housing environment of finisher pigs associated with the development of gastric ulcers

2006

The prevalence and severity of gastric ulcers were investigated in a sample of 50 slaughter pigs from each of 16 commercial farms in the uk. The mean prevalence of ulcers was 19.1 per cent and the mean (se) severity score on the 16 farms was 2.2 (0.15) on a scale from 0 (normal) to 6 (severe). Multivariate regression analysis showed that the type of lying surface provided for the pigs during the finishing phase was the most important factor associated with the occurrence of gastric ulcers in the farms studied. Finisher pigs housed on slatted floors had a significantly higher mean ulcer severity score (P<0.001) than pigs housed on solid concrete floors, which had a significantly higher score (P<0.01) than pigs housed on straw bedding. Feeding a pelleted finisher ration was also associated with significant increase in ulcer severity (P<0.01) compared with feeding an unpelleted ration, but was of less importance than the type of floor. The detrimental influence of feeding pellets was ameliorated by the provision of straw bedding.

“…To avoid the gastric content from spilling, stomachs were removed from the abdominal cavity, preserving 5 cm of duodenum and oesophagus. Upon arrival at the Laboratory for Pig Diseases, an experienced pathologist assessed the stomach health according to macroscopic lesions, based on Nielsen and Ingvartsen's scoring system [18]. According to these lesion scores, stomachs with no lesions, parakeratosis, or erosions were classi ed as "No pars oesophageal ulcers" (NPOU) and stomachs with ulcers, oesophageal stenosis, and scars were classi ed as "Pars oesophageal ulcers" (POU).…”

Background: The objective of this cross-sectional study was to assess the within-herd prevalence of pars oesophageal ulcers (POU) in high-risk Danish herds using commercial diets fed ad libitum. Furthermore, we aimed to estimate the association between gastric content fluidity and POU using a generalised additive model (GAM). The study included 200 clinically healthy nursery pigs randomly selected from ten farms (20 pigs from each farm). The 10 farms were selected based on a suspected high prevalence of gastric ulcers. Post-mortem gastric ulcer assessment was based on macroscopic lesions, and gastric content fluidity was assessed based on the solid particle sedimentation percentage (solid phase). Results: We observed an overall prevalence of 35.5% for POU in nursery pigs. Within-herd prevalence varied considerably among farms, with values ranging from 0% in Farm 1 to 84% in Farm 4. Our model showed strong associations between POU and gastric content fluidity (P<0.001), as well as between POU and farm of origin (P<0.001). In addition, we observed that the risk of POU decreased non-linearly as the gastric content solid phase percentage increased, i.e. as the gastric content became more solid. Conclusion: We have demonstrated that pars oesophageal ulcers are present in Danish herds with nursery pigs fed commercial diets ad libitum. Furthermore, we have established that gastric content fluidity is strongly associated with POU in nursery pigs. Even so, we cannot conclude that gastric content fluidity is solely responsible for POU. Future research should look into the association between pars oesophageal ulcers and both farm management activities and individual pig factors.

“…For pigs in the growing/finishing stages of production, ulceration is a common cause of mortality [ 37 ]. The production systems in which most pigs are kept appear to have a large impact on the incidence of these ulcers, as pigs with access to straw, sawdust, or outdoor paddocks have fewer ulcers than those confined on bare, solid or slatted concrete floors [ 32 , 38 , 39 ].…”

Simple SummaryClimate change is probably the most important environmental issue of our time. Raising animals for food contributes to the production of greenhouse gases implicated in the global warming that is causing climate change. To combat this ecological disaster, a number of mitigation strategies involving changes to agricultural practices have been proposed. However, some of these changes will impact the welfare of farmed animals. This paper reviews selected climate change mitigation strategies and explains how different approaches could have negative or positive effects.AbstractThe objective of this review is to point out that the global dialog on reducing greenhouse gas emissions in animal agriculture has, thus far, not adequately considered animal welfare in proposed climate change mitigation strategies. Many suggested approaches for reducing emissions, most of which could generally be described as calls for the intensification of production, can have substantial effects on the animals. Given the growing world-wide awareness and concern for animal welfare, many of these approaches are not socially sustainable. This review identifies the main emission abatement strategies in the climate change literature that would negatively affect animal welfare and details the associated problems. Alternative strategies are also identified as possible solutions for animal welfare and climate change, and it is suggested that more attention be focused on these types of options when allocating resources, researching mitigation strategies, and making policy decisions on reducing emissions from animal agriculture.
