Low crude protein for post-weaning diarrhea
Michael Bosompem, Michael Wellington, Andrew van Kessel – A recent study examined whether lowering crude protein levels in nursery pig diets could help reduce post-weaning diarrhea caused by rotavirus and E. coli infection. Researchers compared standard diets with low-protein and...
The influence of gestational vitamin supplementation on sow and piglet performance
Past research has shown that increased supplementation of certain vitamins can enhance parameters such as conception rates, litter size, and the passage of maternal immunoglobulins; these experiments generally include increased provision of one or two vitamins. To understand the impact...
2026 PSC Producer Meetings Presentations
2026 PSC Producer Meeting Presentations In collaboration with Zoetis, PIC Canada, and Nutrition Partners AGENDA “Intro – PSC celebrating 35 years” Murray Pettitt, Ph.D. – CEO at Prairie Swine Centre Murray welcomed all participants and gave a short overview of...
Influence of dietary nitrogen content and source on growth performance in finisher pigs
Low-protein diets may be nitrogen-deficient for optimal growth in pigs. Previous work showed a benefit in grower pigs when dietary nitrogen, either through protein or non-protein nitrogen, was increased. The objective of this study was to determine the impact of...
Impact of indigestible protein on nursery pig performance and intestinal health
T.J. Erinle, O.O. Babatunde, J.K. Htoo, S.M. Mendoza, D.A. Columbus – It is unclear what factors are primarily responsible for the negative response to high protein diets. Factors other than total dietary protein content are likely involved. The concept of...

Influence of dietary nitrogen content and source to improve growth performance and lean gain in finisher pigs
Daniel Columbus- Previous trials done in grower pigs have shown that it is possible to replace some dietary protein or amino acids (AA) with a source of non-protein nitrogen (NPN) such as ammonium phosphate, while maintaining growth performance. However, the...

Does providing high vitamin diets in gestation improve performance and passive immunity?
Hannah Burlet, Frederic Beaudoin, Beatrice Sauve, Laetitia Cloutier, Matheus Costa, Danyel Bueno Dalto – While studies have looked at increasing a subset of vitamins during gestation, no published works have looked at increasing the concentrations of all vitamins normally included...
The effect of standard and large pellet creep feed on the performance and blood parameters of weanling pigs
Jen-Yun Chou, Kylie Kallal, Abigail Tillotson – It is recommended that diets designed for young pigs should include less carbohydrates and lysine and more fibre to minimise insulin spikes. High fibre ingredients typically contain higher iron levels compared to more...
Challenges and opportunities for swine nutrition
Dan Columbus – The issues facing pork producers and swine nutritionists moving into the future are similar to what they have been for decades, a need to increase productivity while meeting increasing demands from legislation and consumers to ensure economic,...
