In Germany, fattening pig farming has been characterized in recent years by a further increase in livestock, and by that a spatial concentration and an accumulation of nutrients. The adaptation of livestock farming and feeding to the technical possibilities is therefore needed in order to minimize the release of nitrogen from the protein metabolism and the emissions. Current feeding concepts are only designed for the average of the animals during the fattening period. In consequence, the different needs of individual animals within a group are given insufficient consideration. Animals with feed intake below or above average are not optimally supplied in terms of resource efficiency.

In the project RESAFE, three different aspects will be investigated: Automatically feeding control, protein reduction and optimization of crude fibre supply.

By means of electronic feeding stations for body condition evaluation (OptiSORT) and a closed loop feeding system, it should be possible to adjust the ration during the fattening period according to daily body condition evaluations at any time. Based on these data, the protein supply should be optimized to reduce the absolute protein input, and thus to minimize the emissions.

At the same time, a ration supplemented by regionally cultivated forage crops will be used to increase the crude fibre supply. In this way, an increased microbial fixation of nitrogen in the faeces is to be achieved in order to reduce the release of ammonia from the manure. In addition, an increase of crude fibre will help to avoid luxury consumption in animals with high feed intake.

The aim of the study is to develop and test the described feeding system RESAFE in terms of resource efficiency. The presentation of nutrient balances, emission situation and economic efficiency should increase the farmers' willingness to establish a more environmentally and animal welfare oriented fattening pig production with the help of this novel feeding system.
