Requiring few inputs, protein plant–immature cereal mixtures can guarantee forage stocks in times of shortage. In order to test whether and how the principle of additivity predicts nutritional value, we conducted in vivo digestibility tests and in sacco degradability tests (crude protein degradability, CPD) to evaluate silages from two mixtures with different protein-plant (i.e., pea) contents. The mixture with low pea content, PEAS-l, contained 60 % triticale, 28 % oats and 13 % peas, whereas that with high pea content, PEAS-h, contained 35 % triticale, 24 % oats and 41 % peas). The same tests were conducted with the silages of the constituents (triticale, oats and forage peas). Of the two mixtures, PEAS-h had the highest digestibility figures (for organic matter: 76.5 vs. 61.9 %. The CPD was statistically similar between the mixtures. Furthermore, PEAS-h produced 6.4 MJ net energy content for lactation (NEL) per kg of dry matter (DM), whereas PEAS-l produced 4.9 MJ NEL/ kg DM. Mixtures reconstituted at the manger with the pure silages produced values similar to those of sown mixtures. The constituent additivity hypothesis correctly predicted the values for PEAS-l, the cereal-dominated mixture, but strongly underestimated those for PEAS-h.
Although milk-production oriented (MPO) cow breeds have also become established in the mountain region, farms with the dual-purpose ‘Original Simmental’ breed are proving to be economically viable, with lower costs and higher direct payments making up for lower revenues from milk.
High milk yields before drying-off increase the risk of udder infections during the dry period. An online survey highlights what drying-off methods are currently used and how farmers rate the ‘incomplete milking’ approach for reducing milk yield.

In both sport and alternative agriculture, horses are once again being used as draught animals. Efficient power transmission plays an important role in the wellbeing of draught horses.
