Improvement of protein and energy supply in ruminants and monogastric animals by mixed cropping of maize with runner or scarlet runner beans
In the future, the amount of on-farm or locally produced feedstuff should increase to ensure a sustainable protein supply for farm animals. In our project we analyze the potential of the mixed cropping of maize with runner or scarlet runner beans.
In South America, the provenance countries of maize, the intercropping of maize with runner or scarlet runner beans (Phaseolus vulgaris bzw. P. coccineus) is widely used for human nutrition. The Thünen-Institute of Organic Farming, the Institute of Crop and Soil Science of the Julius Kühn-Institute and the Institute of Animal Nutrition of the Friedrich-Loeffler-Institute develop in a joint research project the concept for mixed cropping further for the production of maize-bean-silage for the conditions in Germany: Dairy cows and pigs should be fed with maize-bean-silage. The project has a clear interdisciplinary structure along the production chain. It includes fodder production, ensilaging, and a feed assessment, which goes beyond the determination of crude nutrients, thus including also secondary metabolites and digestibility. We test the new silages in feeding trials.
At the Thünen-Institute of Organic Farming
For this purpose,
In cooperation with the Institute of Animal Nutrition of the Friedrich-Loeffler-Institute digestibility trials with sheep will be carried out. For this purpose defined model silages with different percentages of runner beans will be prepared and fed to the sheep to calculate the digestibility of the crude nutrients.
The field trials were established after the project launch in spring 2014, so still there are no results available.
