EU FP7 Project to develop
Innovative and practical management approaches to reduce nitrogen excretion by ruminants.
Dairying is an important sector of EU agriculture, but intensification has been accompanied by an increase in nitrogen surplus in the cycle between the animal, the crop and the soil. This has a negative environmental impact on groundwater (pollution with nitrates), surface water (eutrophication) and on the atmosphere (de-nitrification and ammonia volatilisation). The EU seeks to stimulate measures that improve management of nutrients, waste and water as a start to move to management practices beyond “usual good-farming practice”.
The objective of RedNEx is to develop innovative
and practical management approaches for dairy cows that reduce N
excretion into the environment through the optimization of rumen
function, an improved understanding and prediction of dietary N
utilization for milk production, and excretion in urine and faeces.
Dissemination and knowledge interaction will use a participatory
approach to include the views of stakeholders and recognition of the
need to provide support to EU neighbours.
The project is coordinated by Ad van Vuuren of ASG Veehouderij B.V. in the Netherlands and involves 10 other partners:
- Aberystwyth University, United Kingdom
- European Federation of Animal Science, Italy
- Friedrich-Löffler-Institut. Bundesforschungsinstitut für Tiergesundheit, Germany
- Institut National de la Recherche Agronomique, France
- Slovenske Centrum Polnohospodarskeho Vyskumu, Slovakia
- Universitat Autonoma de Barcelona, Spain
- Universiteit Gent, Belgium
- University of Aarhus, Denmark
- University of Reading, United Kingdom
- Wageningen Universiteit, Netherlands
The CowNex simulator created by INRA for the RedNex project is used to calculate protein synthesis and nitrogen excretion in a dairy cattle herd, including heifers, depending on herd management.
It performs these calculations throughout the year and measures the impact of management changes, particularly nutrition, on the efficiency of nitrogen use by the herd and the release of fecal or urine nitrogen.
