Strategic application of exogenous enzymes to enhance nutritive and functional value of fibrous feedstuffs for monogastric farm animals

In the context of burgeoning human population and attendant demand for food, feed supply is challenged by limited availability of natural resources, climate change pressure and food-feed-biofuel competition. Monogastric animals are increasingly being fed significant quantities of cost-effective alternative high fiber feedstuffs unacceptable for human consumption. Restriction on use of antibiotics is also placing greater emphasis on dietary strategies for promoting and maintaining a healthy and functional gastrointestinal tract. The proposed research will investigate application of fiber degrading enzymes to develop nutritional strategies to steer gastrointestinal health and function for enhanced nutrients utilization and animal performance. The research program will pursue two themes: 1) Fiber solubilization for enhanced nutrients utilization and fermentability, and 2) Fiber hydrolysis for generation of hydrolysates with prebiotic effects. The ideation and innovation to be investigated will improve nutrients utilization, gut health and therefore overall reduction on antimicrobial use. Direct benefits to Canadians will range from feed cost reduction for farmers and feed manufacturers, increased use co-products from bioethanol and milling industries, reduced use of antibiotics and sustainable animal production through reduced nutrients excretion on farms, and training of highly qualified researchers who will continue to impart their knowledge in both academia and industry.
