In a three-month trial involving two groups of 15 dairy cows each, Agroscope FAT Tänikon investigated whether mixing the feed components of the basic ration or distributing a non-mixed ration had an impact on feed intake and milk yield. In the mixed-ration system, the basic ration, consisting of various silages and ventilated hay, was distributed by a diet feeder, whilst the non-mixed ration was distributed by a feeding bucket fixed on the self-propelled loader. No relevant differences between the two systems were observed in terms of basic feed intake, energy-corrected milk yield or milk components. Compared to several other feed-distribution techniques, the mixed ration system (i.e. the one using a diet feeder to distribute the feed) proved the most advantageous from a work economics viewpoint. With the diet feeder enabling the feed components to be collected from their storage places on the farm, then transported and directly distributed to the animals, the feed transport- and distribution process was almost effortless. A cost comparison shows, however, that these undoubted advantages in terms of work economics come at a price. The system commonly used, consisting of a diet feeder and (manual) feed removal from the tower silo, involves the highest costs per working hour saved (CHF 55.-) in comparison to the exclusively manual system, in spite of taking only half of the machine costs into account (50 % ownership). The simpler system using a feeding bucket allows a halving of the costs per manpower hour with full ownership. The cheapest way to save working time is to use a horizontal silo in combination with an unloading/transport/distribution system, or a diet feeder equipped with a silo unloader. These systems also allow a significant reduction of the physical workload.
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.
