“…The prevalence of gastric lesions in this study was 25.3% as 19 out of the 75 stomachs had visible gross lesions. This included a prevalence of 17.3% (13) in the non-glandular stomach and 21.3% (16) in the glandular stomach ( Table 1). Epithelial changes were restricted to the non-glandular region.…”

“…The stomach of the pig is characterized by its great fragility, particularly in the pars oesophagea zone close to the cardiac region which increases its susceptibility to lesions (Omotosho et al, 2015). Investigations have shown that gastric lesions including erosions and ulcerations are common conditions in pigs especially in growing pigs than breeding animals in Nigeria (Majekodunmi et al, 2013). Gastric lesions in pigs include ulcerations, lacerations, erosions and epithelial changes.…”

Information on the occurrence of gastric lesions in pigs in Ghana is lacking in literature. This study was designed as a preliminary investigation to determine the occurrence and pattern of gastric lesion in pigs in Ghana. Ante-mortem animal assessment and post-slaughter stomach evaluation were conducted on 75 pigs out of a total of 694 slaughtered between October, 2014 and March, 2015 at the Kumasi abattoir. The gross lesions observed on the gastric mucosa were graded using standard technique. Stomach contents were assessed and tissue sections were used for histopathology evaluation. The data obtained were cross tabulated and analyzed using Chi-square and One-way ANOVA. Significance was determined at p < 0.05.The prevalence of gastric lesions in the sampled population was 25.3% while the non-glandular stomach (pars oesophagea) and glandular had a prevalence of 17.3% and 21.3% respectively. The predominant lesions observed were epithelial changes in the pars oesophagea and ulcers in glandular region of the stomach. Epithelial changes were restricted to the non-glandular region and it affected 8 (42.1%) of the stomachs with lesions. Erosions and ulceration were observed in the pars oesophagea and glandular stomach while mucosa damage was restricted to the glandular stomach. Lesions were observed in the two breeds studied and the stomach contents of the pigs were mostly finely grounded compounded feed, millet/maize chaff or cassava based feed. Histopathological evaluation of gastric mucosa tissues revealed erosion, multifocal ulcerations with occasional presence of silver staining micro-organisms. There was no significant association between breed, age, sex and occurrence of gastric lesions in pigs. Stomach content volume and feed type were identified as risk factors. Evidence of stomach infection with spirochetes was also observed. Our findings reveal the occurrence of gastric lesions in pigs in Ghana and its associated risk factors. It is therefore recommended that stake-holders should adopt on-farm and abattoir periodic monitoring of the condition as well as improved animal welfare and hygiene practices both on farm and in transit.

“…Research conducted in England by Swaby and Gregory (2012) reported a prevalence of 79.8% of gastroesophageal ulcers of different degrees in 9827 slaughter pigs from 60 farms. Majekodunmi et al (2013) examined stomachs of 100 slaughtered pigs from an abattoir in Nigeria 21 (21%) of them had chronic ulcers. The findings of gastric ulcers reported in Brazil and in other countries are much higher than those obtained in this survey, which the presence of active or chronic ulcer represented 16% (64/400) of the animals (Figure 1).…”

Gastric lesions are a common problem in intensive pig production and it is often detected at slaughter. The current study aims to evaluate the prevalence of gastric lesions in finishing and breeding pigs at the time of slaughter. It was conducted in a slaughterhouse in Franca region-São Paulo State, from October to November 2013 and in July 2014. Four hundred (400) stomachs from slaughtered pigs were analyzed for the presence of macroscopic lesions suggesting gastric ulcer. Scores from 0 to 4 were attributed to the stomachs depending on the extent of the lesions, namely: score 0-Normal stomach; score 1-stomach showing parakeratosis; score 2-stomach showing active or chronic ulcer covering less than 33% of the Pars oesophagea; score 3-stomach showing active or chronic ulcer covering from 33 to 66% of the Pars oesophagea; score 4-stomach showing active or chronic ulcer covering more than 66% of the Pars oesophagea. Score-3 lesions-i.e., lesions showing active or chronic ulcer covering from 33 to 66% of the Pars oesophagea-were most frequently found, thus corresponding to 43.2% (173/400) of the evaluated organs. Few stomachs (5/400) showed intact mucosae, i.e., they were score 0, and corresponded to 1.25% of the evaluated stomachs. It was concluded that the prevalence of gastric lesions in pigs from intensive system pig farm was 98.75% and that the active or chronic ulcer covering from 33 to 66% of the Pars oesophagea was the most frequently found lesion.

“…This is a problem worldwide. Reports vary, with incidence of pigs showing distinct signs of ulceration between farming operations ranging from zero to nearly 90% [ 32 , 33 , 34 , 35 , 36 ]. For pigs in the growing/finishing stages of production, ulceration is a common cause of mortality [ 37 ].…”

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.
