In the framework of the current revision of the Swiss Fertilizer Guidelines (SFG) the guide values for nutrient excretion of pigs were checked and adapted to current production practice. The principle used for calculating excretions is input in feed minus retention in in the growth of piglets and young sows. For fattening pigs all the relevant information on current production practice could be derived from representative farm data. For sows, in addition to analysed farm data information was derived from the current feeding recommendations. For the feed content, the mean values for normal feed without reduced protein and phosphorous content from a representative survey was used for all animal categories. For fattening pigs the nitrogen (N) and phosphorus (P) excretions which are important for the compulsory nutrient balance of farms remained practically the same as according to the previous guide values. This was possible because the increased productivity per place per year was counterbalanced by a better feed conversion efficiency and a reduction of the protein and P content of the feed. For sows excretions increase quite considerably because of the higher productivity (piglets per sow per year, shorter suckling period etc.) and changes in the feeding recommendations.
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.
