In 2000, we tested the efficacy of the two silage additives Naturasil (concentrate) and Topsilage. Both products are containing lactic acid bacteria meant to promote the main fermentation in silages. The trials were carried out in small-scale silos with a mixture of lucerne and cocksfoot. Forage of the first and also of the second cut was ensiled at two different dry matter levels (about 20 and 30 % dry matter). The silos were opened after a storage time of about 100 days.<br><br>The silages without additive contained either butyric acid or high amounts of acetic acid, both indicating a bad fermentation. The two silage additives Naturasil and Topsilage did improve the fermentation quality of the silages made from forages which are difficult or less difficult to ensile. Based on these results both products were authorized.
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.
