Whole-plant oat silages in spite of a high dry matter content often contain butyric acid. Urea as an additive enables to inhibit butyric acid fermentation and to kill off clostridial spores. Acid whole-plant oat silages, which are free of butyric acid, and mixtures from whole plant oat silage and grass silage quickly deteriorate in air, whereas the alkaline urea treated silages on its own are very stable under aerobic conditions. Urea treatment increases the digestibility of whole-plant oat silages significantly. In opposite to sheep, beef cattle may refuse urea treated alkaline silages fed as a sole forage. After mixing them with a grass silage, however, the urea treated silages from wholeplant oats are well accepted.
