Dr. Dan Columbus – 2019 CSAS Young Scientist Award

Dr. Dan Columbus Canadian Society of Animal Science, 2019 Young Scientist Award Dr. Daniel Columbus is a Research Scientist in Nutrition at Prairie Swine Centre and Adjunct Professor in the Department of Animal and Poultry Science at the University of Saskatchewan.  Dr. Columbus completed his BSc, MSc, and...

Assessing Particle Size and the Cost of Grinding

Particle size reduction improves feed efficiency in all stages of the production cycle in pigs. Based on studies by researchers at Kansas State University (KSU), an average particle size of 700 to 800 microns (um) is recommended. However, this recommendation is based on studies conducted using corn-soybean meal based diets. To our...

Interaction of Dietary Energy and Phytase on Performance of Weanling Pigs

Approximately 60 to 80% of the phosphorus (P) in cereal grains and oil seeds is bound to phytate and unavailable to monograstics, including swine. Supplementing swine diets with the phytase enzyme improves P availability and retention. The phytate molecule complexes other minerals, proteins, and starch, however, the research examining the...

The Interaction Between Pig Density and Dietary Energy on Performance

Dietary net energy and stocking density independently affect performance, feed utilization and profits in the finisher barn. The objective of this experiment was to assess the interactions of stocking density and dietary energy, and determine how these interactions affect net income. When stocking density was increased, the performance of finishing...

Dietary ω-6 to ω-3 Ratio Impacts Nursery Pigs

Results from these experiments indicate that altering the omega(ω)-6 to ω-3 fatty acid (FA) ratio can improve nursery pig performance, and protein deposition, potentially by diverting nutrients away from an unnecessary inflammatory response. Additionally, we found no effects on piglet performance or health by altering the amount without changing the...
