In a trial we investigated the influence of the filling time on silage quality. On the one hand we ensiled the pressed pulp after the transport from the sugar factory on the same day and on the other hand, ensiling was carried out after two days. In all variants we used 9 m3 silos and 700 l containers. Furthermore, we ensiled pressed pulp without and with a silage additive. The additive we applied either at the sugar factory or at filling.<br>Measurements of the temperature in the silages showed that the decrease of the temperature in the 700 l containers was faster than in the 9 m3 silos. Moreover, in the 9 m3 silos temperature differences were found between the centre and the edge of the silo.<br>Along with the relatively fast decrease of the temperature there was not an intensive lactic acid fermentation and the pH was not decreased very much. Nevertheless, under these conditions no butyric acid was found.<br>With the delayed filling time less sugar was found in the pressed pulp at ensiling and the fermentation quality was negatively influenced. The silages were also more susceptible for aerobic instability. Under these conditions the fermentation quality was improved by the silage additive.

In both sport and alternative agriculture, horses are once again being used as draught animals. Efficient power transmission plays an important role in the wellbeing of draught horses.
A study by Vetsuisse shows that the outdoor veal calf concept reduces antibiotic consumption in calf fattening by 80%. AGRIDEA has examined the economic viability of outdoor veal calf production and concludes that it cannot compete with conventional veal calf fattening.
In contrast to pigs, dairy cattle are as yet rarely fed protein-reduced diets. Studies show that there is also potential for protein savings in cattle, and thus for reducing ammonia emissions.
