Dyck points to the 2020 published study of another research group, led by Dr Olayiwola Adeola at Purdue University, which investigated the SID of full-fat canola seeds for pigs. The team found that ground seeds are high in both energy and protein and can therefore be easily incorporated into ra- tions for swine. “The amino acids in this ingredient are also readily digested by growing pigs,” says Dyck. She adds that while data on SID are almost exclusively deter- mined with growing pigs, research published in 2019 from the Nyachoti Lab at the University of Manitoba found that SID of canola meal is greater for adult sows than for growing pigs. The researchers also determined that the SID values of argi- nine, histidine, lysine, methionine, tryptophan and valine were greater with a treatment of a multicarbohydrase enzyme. Additional research from the University of Manitoba present- ed in 2020 evaluated the effects of heat treatment on phos- phorus digestibility. The results found that phytase enzymes should be used in order to increase phosphorus availability of canola meal in swine diets.
A bright future Newkirk believes use of canola meal in pigs, poultry and be- yond will continue to grow because consistency is excellent
and it’s a fully palatable ingredient for pigs. “Much of the world has become highly dependent on SBM, but with price fluctuations and trade barriers they are always looking for al- ternatives,” he adds. “Once they get some experience with canola meal, they usually increase the use.” When recently doing seminars in Malaysia, Newkirk says he was left with the impression that there may be significant growth for canola meal in that market. “Price-wise it made sense,” he says. “The nutritionists just need to get more familiar and comfortable with it.” For his part, Stein does not expect usage of canola meal to in- crease significantly in the US because SBM is likely to remain less expensive on an amino acid basis. “But of course in west- ern Canada, in Europe, and in other parts of the world where canola but not soybeans can be grown, I think we can easily see an increase in canola meal usage in swine diets because, as mentioned, pigs perform very well on canola meal diets. I think the varieties of canola we have today can result in very good pig performance.” He adds that “we now have high-protein canola available. These varieties result in canola meal with 44–48% crude pro- tein and they are very interesting to use in pig diets. So, this will likely also contribute to increased usage of canola in the future.”

A field of canola. The crop is used pretty exten- sively in swine in regions where it’s produced.
