Sask research finds pea starch makes excellent feed ingredient if flow issues can be resolved

By Bruce Cochrane, Farmscape

A swine nutritionist with the University of Saskatchewan says, if flow issues can be resolved, pea starch can provide an excellent source of energy in swine rations.

Research conducted by the University of Saskatchewan in partnership with the Prairie Swine Center and the Canadian Feed Research Centre in North Battleford showed pigs fed pelleted rations containing 40 percent pea starch grew really well with great feed efficiency.

Dr. Denise Beaulieu, an Assistant Professor Monogastric Nutrition with the University of Saskatchewan, said she is seeing an increased interest in pea starch primarily because of availability and we expect availability to increase further in the future.

”The pea starch is a byproduct of the pea protein industries. As we see these increased meat substitutes available, a lot of them are based on peas. If you take the protein out of the peas and make a meat substitute, you're left with this pea starch. There's a lot of interest in it because it's out there, it's available and it's a really good source of energy in our pig diets,” explained Dr. Denise Beaulieu from the University of Saskatchewan, who conducts applied swine research focusing on nutrition, specifically the role of alternative feedstuffs to improve the economic and environmental sustainability of the swine and poultry industries.

“In terms of cost and availability, there are several plants here in western Canada that are producing the pea protein and thus have pea starch available as a byproduct. One of the main factors that we are looking at is, when they make this pea starch, the process they use to make it results in a product that's a really low particle size. One of the issues we have, because of this low particle size, is the handling of it. It doesn't handle well in our feed systems, it doesn't handle well when we're mixing it. That is one thing that we have to be aware of when we're using it in our diets that we may have to pellet our diets or process our diets in some way so that we can get it through our systems,” added Dr. Beaulieu.

Prior to joining the University of Saskatchewan, Dr. Beaulieu spent almost 15 years at the Prairie Swine Centre in Saskatoon. She maintains adjunct scientist status at Prairie Swine Centre, using the facilities for research trials and actively participates in their knowledge transfer programs.

Dr. Beaulieu said, if you can find pea starch at a reasonable cost, it can be a very good ingredient.
She suggested pelleting the ration to address the flow issues or restricting the amount included in the diets to 10 percent.

It's raining today, a perfect day to be shearing sheep but no, that has been cancelled again. Instead, watch as the sheep deal with the rain - we have such fair weather sheep! Lol!
