Research underway at the Western College of Veterinary Medicine aims to allow swine producers to increase the inclusion of pea starch in rations without increasing the incidence of gastric ulcers. An increased use of peas to provide protein for products such as energy drinks has resulted in an abundance of finely ground starch co-products but, when fed to pigs, extremely finely ground feed ingredients are known to cause gastric ulcers.
Dr. Matt Loewen, an Associate Professor in Veterinary Medical Biosciences with the Western College of Veterinary Medicine, says we would like to use more of this cheap energy source in swine rations so the goal is to identify the mechanisms responsible for these ulcers, determine safe inclusion levels and find additives to prevent those gastric ulcers from occurring.
Clip-Dr. Matt Loewen-Western College of Veterinary Medicine:
There's probably three lines of thought on why this finely ground pea starch results in more gastric ulcers. One is a physical one in that it somehow changes the viscosity of the gastric solution that's in the stomach once the pigs eat so somehow the viscosity of it's changed so there's more gastric reflux so the viscosity of the actual ingestia has changed and that somehow results in more ulcers occurring.
