The efficacy of two silage additives on aerobic stability was investigated in maize silage in comparison to a treatment without additive and a treatment with propionic acid. The maize was harvested at two different dry matter levels (31 and 37 % 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.<br><br>All silages showed a good fermentation quality. With the additive Silasil Mais Pro, which contains lactic acid bacteria and chemical substances, the aerobic stability of the silages was improved. The product Lalsil MS01 NF, which contains lactic and propionic acid bacteria, did not improve the aerobic stability neither in the silage with 31 % DM nor in the one with 37 % DM.
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.
