Das H2020-Projekt OK-Net EcoFeed unterstützt Bio-Schweine- und -Geflügelbauern bei der Erreichung des Ziels 100 % ökologische und regionale Futtermittel zu verwenden. Geschaffen wurde ein europäisches Netzwerk von Innovationsgruppen, bei denen ein Austausch zwischen Landwirten, Wirtschaftsakteuren, Forschern und Beratern angeregt wurde. In kleinen Versuchen, die an die Bedürfnisse der Landwirte angepasst sind, wurden verschiedene Ansätze getestet. Die Landwirte in der Projektgruppe haben die Brennnessel als Eiweißfuttermittel betrachtet. Dazu wurden Fütterungsversuche bei Legehennen und Anbauversuche zur erfolgreichen Kultivierung durchgeführt. Dieses Video gibt Auskunft über die Versuche.

A European network of Innovation Groups was created, stimulating exchange between farmers, economic actors, researchers and advisors. Different approaches were tested in small-scale trials adapted to farmers' needs. The farmers in the project group tested nettles as a protein feed. For this purpose, feeding trials were carried out on laying hens and cultivation trials on successful cultivation. This video provides information about the tooltests. Test 1 was a feeding trial with laying hens. Dried nettles were used in proportions of 10% and 5% in the respective rations of the farms. The feed was fed ad libitum to almost 300 laying hens for 10 and 26 days. Advisor assessment and bird acceptance of the feed were very positive. The feed intake did not change (120-130 g per hen and day). The faeces were very solid and tended to be positively influenced. The laying performance of the animals was constant. The quality characteristics (egg shell, yolk colour, protein quality) did not change. Test 2 was a cultivation trial with nettles. On two trial plots the sowing was done by purchased seeds (no-till) and by vegetative propagation (stolons). During growing, different fertiliser applications were tested. Consisting of chicken manure and sulphur (Kieserite 25 % MgO, 50 % SO3) in autumn and spring to provide information on the influence of sulphur applications on methionine concentration. Purchased seeds had a poor germination. Propagation from cuttings (stolons) is more effective. The crop should not be harvested too late, in order to achieve the highest leaf proportion. Any influence of fertiliser application could not be determined. Clearly visible is the influence of the soil temperature. Later cuts provided significantly better methionine yields. Analysis of the pure leaf mass yielded good methionine values up to 4.52 g/kg DM88. Compared to small-grained legumes, nettle cultivation is very costly and the additional methionine yields are too low when considering the extra cost. The effects of nettles as feed for poultry were mostly neutral: on laying performance, egg quality, animal health and behavior. The birds acceptance of nettle as feed was very good.
