The efficacy of the four silage additives Bonsilage Mais Granulat, Bonsilage Mais flüssig, Multifor-Sil Corn and NH 708 uroSIL on aerobic stability was investigated in maize silage in comparison to a treatment without additive and treatments with propionic acid (two dosages). The maize was harvested at three different dry matter levels (26, 30 and 34 % dry matter) and ensiled in 1.5 litre laboratory scale silos. 7 days before the silos were opened the silage underwent an air stress for 24 hours during the storage period. All silages showed a good fermentation quality. With the additives Bonsilage Mais liquid and Multifor-Sil Corn the aerobic stability of the silages was improved. The silages with the product NH 708 uroSIL as well as with Luprosil (deep dosage) heated up earlier in comparison to the untreated silage, at 26 % DM. The same was also observed with the product Bonsilage corn Granulat at 34 % DM.
Birdsfoot trefoil and sainfoin are used in mixtures for perennial hay meadows and for tannin-containing fodder. Agroscope is adding two new cultivars of birdsfoot trefoil to the ‘List of Recommended Varieties of Forage Plants’, whilst there is no change in the case of sainfoin.
Tall oat grass and golden oat grass are typical hay-meadow grasses that are also suitable for forage mixtures. Of the four tall and three golden oat grass varieties tested, only one new variety of tall oat grass is likely to make it onto the List of Recommended Varieties.

FiBL and Agroscope investigated bread wheat varieties to determine their yield and quality stability. The results show that the choice of variety must be adapted to the site and that high yield potential does not go hand-in-hand with a high protein content.
