Full grazing or indoor feeding of fresh herbage and partial grazing are common feeding systems for dairy cows in Switzerland. Project Hohenrain II investigated a comparison of three different grassland-based milk production systems, a partial grazing with indoor feeding of fresh grass with reduced and increased concentrate supplementation was compared with the full grazing system with seasonal calving and no concentrate supplementation during three years. In the years 2014 and 2015, herbage from pastures and for fresh indoor feeding were regularly taken during the growing periods and the minerals calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K), sodium (Na), copper ( Cu), iron (Fe), manganese (Mn) and zinc (Zn) were analysed. Herbage from pastures had significantly lower Ca and higher P, K, Cu and Zn contents than herbage for fresh indoor feeding. This is mainly due to the different stages of development of the herbage. No significant differences were determined in the Mg content. Apart from the sodium content, the mineral contents varied significantly in the herbage during the growing periods. With the feeding of herbage, the needs of a dairy cow up to a milk yield of 30 kg per day could be covered by Ca, P, K, Cu, Fe and Mn. On the other hand, this was not the case for Mg, Na and Zn.
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.
