Soybean and canola meal are commonly used plant-based protein sources in the livestock industry. However, they also contain anti-nutritional factors such as allergens, high molecular weight, difficult to digest proteins. In addition, the contents of cellulose and hemicellulose are also quite high ranging from 19-22% in these feedstuffs. Due to the lack of cellulase and hemicellulase in the pig gastro-intestine track, this high percentage of fiber in the canola and soybean meal limits their utilization. Microbial fermentation using bacteria is one of the efficient and cost effective approaches to improve feed nutritional value. We have previously established a laboratory scale fermentation system to break down the allergen, non-digestible and antinutritional components in soybean meal to improve their nutrient value. CBS Bio-Platforms, a leader in the field working to unlock prebiotics and proteins from plants for livestock feed, is collaborating with us via the NSERC Alliance funding opportunity to further develop the system to move the technology to application. At this second phase of research, we aim to further expand and optimize condition for large scale fermentation, particular focus on Canadian sourced soybean and canola, and demonstrate its benefit for pork production. The resulting product will be an improved highly digestible local plant protein source that can be included into livestock feeds as an affordable alternative to animal-based protein sources.

大豆和油菜籽粉是畜牧业中常用的植物性蛋白质来源。然而，它们也含有抗营养因子，如过敏原、高分子量、难以消化的蛋白质。此外，这些饲料中纤维素和半纤维素的含量也相当高，在19-22%之间。由于猪胃肠道中缺乏纤维素酶和半纤维素酶，油菜籽和豆粕中的高纤维百分比限制了它们的利用。利用细菌进行微生物发酵是提高饲料营养价值的有效和经济的方法之一。我们之前建立了一个实验室规模的发酵系统，以分解豆粕中的过敏原，不易消化和抗营养成分，以提高其营养价值。CBS Bio-Platforms是该领域的领导者，致力于从植物中释放益生元和蛋白质用于牲畜饲料，正在通过NSERC联盟的资助机会与我们合作，进一步开发该系统，以将该技术应用于应用。在第二阶段的研究中，我们的目标是进一步扩大和优化大规模发酵的条件，特别关注加拿大来源的大豆和油菜，并证明其对猪肉生产的好处。由此产生的产品将是一种改进的高度可消化的本地植物蛋白源，可以作为动物蛋白源的负担得起的替代品纳入牲畜饲料中。
