In a field survey of the Swiss College for Agriculture and a complementary trial at the Swiss Federal Research Station for Animal Production (RAP), the mineral content of grass from continuous short grass pastures and rotational pastures was analyzed. The order of magnitude of the mineral content of investigated continuous short grass pastures and rotational pastures generally corresponds to tabulated values for Swiss herbage (RAP, 1994). There exist only minor differences between feed samples from continuous short grass pastures and rotational pastures. The early regrowths tend to contain less calcium and magnesium than later regrowths. On the other hand, phosphorous content slightly decreases from earlier to later regrowths. These findings are valid for both grazing systems. Compared to the trace element feeding recommendations for dairy cows, herbage from continuous short grass pastures and rotational pastures is short of Cu, Zn and Se but rich in Mn.

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.
A study by Vetsuisse shows that the outdoor veal calf concept reduces antibiotic consumption in calf fattening by 80%. AGRIDEA has examined the economic viability of outdoor veal calf production and concludes that it cannot compete with conventional veal calf fattening.
In contrast to pigs, dairy cattle are as yet rarely fed protein-reduced diets. Studies show that there is also potential for protein savings in cattle, and thus for reducing ammonia emissions.
