Seven different types of concrete, three types of asphaltic concrete and three types of mastic asphalt were exposed to silage juice of maize during 9 weeks. The samples were mounted on transmission chains making an alternation between immersion and drying possible. The measuring of the weight losses showed that the resistance of the concrete could hardly be increased by adding substances and using alternative cement types. The losses noted for asphaltic concrete were about the same as for concrete, except the samples with stone mastic asphalt and those enriched with Trinidad asphalt – they both resisted significantly better. The weight losses of the samples of mastic asphalt varied between 30 and 40 % compared to those of concrete. Permeability tests performed during six weeks showed that a layer thickness of 7 cm was enough for making the three types of asphaltic concrete impermeable to silage juice. From a financial point of view, silage floors made of asphaltic concrete and applied in one layer proved to be the optimal solution.
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.
