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.
While botanical composition, growth cycle and phenological stage are integral factors, they are not the sole determinants of the quality of grass silages from intensively managed permanent meadows.
Food that is unsuitable for human consumption does not affect the growth performance or carcass composition of pigs to which it is fed. This makes it a promising solution for reducing food waste.
Horses are ridden or driven on a variety of surfaces, which differently absorb the impact forces exerted on hooves, limbs and the horse's entire body. Objective measurement of the functional properties of equestrian arena surfaces is therefore of great importance.
