Transepithelial ion transport in the stomach of pigs exposed to gastric ulcer conditions
Gastric ulcers in pigs increase significantly when stressful events occur. However, the exact causes of these gastric ulcerations remain unclear. Gastric acid production is known to be influenced by anionic secretion. An Ussing chamber study was conducted to evaluate the...
Developing an Indigestible Protein Index to Investigate the Effects of Dietary Protein in Pigs
It is unclear what causes the inconsistent negative effects of high protein diets in nursery pigs, but it could be due to protein source or indigestible protein (IDP) content. A literature search and meta-analysis was done that included ninety-four studies...
Impact of fibre on performance and intestinal health of pigs fed a high indigestible protein level
Dietary indigestible protein (IDP) may be a better indicator of potential negative dietary effects than total protein, likely because IDP is available as substrate for microbial fermentation in the hindgut resulting in the production of harmful metabolites. Fermentation of fibre,...
Insights into mycotoxins in swine diets
Mycotoxins are regularly found in ingredients used in swine diets and the issue seems to be getting worse. That’s why Dan Columbus, nutrition researcher at Prairie Swine Centre, presented some insights into mycotoxins in swine diets at the 2024 PSC...
Advances in nutrition for improved pig health
Dan Columbus, nutrition researcher at Prairie Swine Centre, presented his work regarding advances in nutrition for pig health at the 2024 PSC Producer Meetings. Nutrient requirements for development and immune response will be different from those for growth performance. In...

Impact of dietary Calcium and Phosphorus on sow reproduction and bone development in piglets
Two experiments were conducted to determine the influence of dietary Ca and P levels in the gestation and lactation diets of high producing sows on Ca and P balance, productivity, bone turnover, and bone development in piglets. The objective of...
Response of growing hogs to the inclusion of hybrid rye in low or high energy diets
Hybrid rye has the potential to be a cost-effective ingredient in swine diets. Several studies observed slightly reduced feed intake for pigs fed increasing hybrid rye substituting for wheat or corn, which in turn resulted in lower average daily weight...
Dietary nitrogen content affects lysine requirement and nitrogen utilization and retention in growing pigs
When dietary protein is reduced by more than 3%, non-essential amino acids or total dietary protein may become limiting for maximum nitrogen (N) retention (i.e., lean gain) and growth performance. It has been suggested that the ratio of essential amino...
Inclusion of non-protein nitrogen and lysine in grower pig diets on growth performance
Results from our previous study demonstrated that inclusion of non-protein nitrogen (NPN) in a diet with a high essential amino acid-nitrogen:total nitrogen (E:T) ratio (i.e. limiting in total nitrogen [N]) increased the Lys requirement and maximum N retention in growing...
