During the sugar production in 2014, around 4 % molasses was added to the pressed sugar-beet pulp in both the Aarberg and Frauenfeld sugar refineries. In the present survey, we investigated the influence of higher additions of molasses on silage quality and aerobic stability. Zero, 7 or 14 % molasses was added to the pressed sugar-beet pulp and the feed was ensiled in round bales. Samples were taken at the time of ensiling as well as after a storage period of 120 and 377 days. In the fresh material and the silages the dry matter and nutrient content were analyzed. Furthermore, the fermentation parameters, the microbiological quality and the aerobic stability of the silages were investigated. The higher the percentage of molasses, the higher the DM content, and in particular the sugar content, of the basic raw material. For its part, the fermentation process broke down a large proportion of the sugar. Silages that had been stored for four months were characterized by good fermentation quality and microbiological quality. Acetic acid content rose in bales stored for over a year. This brought about an improvement in the aerobic stability of the silages, especially in the two variants with 7 and 14 % molasses respectively.
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.
