Objectives of RUMEN-UP

The project will explore the potential of new plant species or plant extracts as feed additives for ruminants in order to overcome long-standing problems of animal welfare and environmental damage. A common resource of plant materials will be created. Samples will be identified within the collection which inhibit lactic acid production, bloat, methane formation or nitrogen losses resulting from rumen fermentation. Plants suitable for agronomic exploitation and extracts which might be exploited commercially will be identified and tested further in feasibility experiments. A successful outcome of the project will lead to new crops or plant extracts being used as feed additives, replacing synthetic additives including antibiotics, a greater diversity of plant species being used in agriculture, improved animal health and welfare, and decreased emissions into the environment of methane and nitrogen-rich animal wastes.
