Quebec is the leader in maple syrup production with an average of 72% of the world maple syrup production over the last 30 years. This product is exported to more than 53 countries where 80% of its production is sold. The maple syrup industry had a 29% increase in exports and a 75% increase in sales over the last five years, and a record production in 2017 of 152.2 million pounds of maple syrup. With the emerging technologies in maple syrup production and climate change, we have been witnessing for some years now, an increase in volumes of maple syrup produced with off-flavors that considerably affect its economic value. In addition, the maple industry generates high amounts of maple sand, a by-product that is still not exploited but shares high nutritional components of maple syrup. Therefore there is an urgent need among producers of maple syrup for the development of new avenues allowing the valorization of these by-products whose nutritional value remains very interesting. In this project, we propose to develop a large scale process for the production of food supplements based on maple by-products intended for animal nutrition. This project also aims to evaluate the impact of these supplements on the modulation of the intestinal microbiota in pigs while controlling the undesirable enteric flora. The specific objectives of this project are: Objective 1. To characterize various maple by-products at physicochemical and microbiological levels; Objective 2. Develop technological processes for the creation, preparation and long-term stabilization of supplements based on maple by-products; Objective 3. To evaluate the digestibility and stability in the gastrointestinal tract of these supplements and their effects on the colonic microbiota; Objective 4. To investigate the impact of supplements on zootechnical performance in post-weaning pigs; Objective 5. Conduct a technico-economic study to validate the potential use of supplements for animal nutrition.

魁北克是枫糖浆生产的领导者，在过去的30年里，平均占世界枫糖浆产量的72%。该产品出口到超过53个国家，其中80%的产品销售。在过去五年中，枫糖浆行业的出口增长了29%，销售额增长了75%，2017年的枫糖浆产量达到创纪录的1.522亿磅。随着枫糖浆生产和气候变化的新兴技术，我们已经目睹了几年来，枫糖浆产量的增加与异味，大大影响了其经济价值。此外，枫树产业产生大量的枫砂，这是一种尚未开发的副产品，但具有枫糖浆的高营养成分。因此，枫糖浆生产商迫切需要开发新的途径，使这些副产品的营养价值保持非常有趣。在这个项目中，我们建议开发一种基于枫树副产品用于动物营养的食品补充剂的大规模生产工艺。该项目还旨在评估这些补充剂对调节猪肠道微生物群的影响，同时控制不需要的肠道植物群。该项目的具体目标是：目标1。在理化和微生物水平上表征各种枫树副产品;目标2。开发基于枫树副产品的补充剂的创造、制备和长期稳定的技术流程;目标3。评估这些补充剂在胃肠道中的消化率和稳定性及其对结肠微生物群的影响;目的4.研究日粮添加剂对断奶仔猪生产性能的影响;目的5。进行技术经济研究，以验证动物营养补充剂的潜在用途。
