Animal welfare barn reduces emissions similar to exhaust air purification
In what is currently the largest research project in Austria in the field of pig emissions , carried out via the EU's EIP-AGRI program, a new husbandry system based on animal welfare developed with three functional areas and a permanent outdoor run for the pigs.
The investigations lasted more than two years and were carried out in a cross-border joint project alongside the main responsibility of Raumberg-Gumpenstein.
In addition to emissions of ammonia, odor and noise , the behavior of the animals investigated.
- the workload and
- the construction costs are included as well as
- Special attention was paid to the fine dust content of the stable air due to the straw bedding
The results positively exceed the expected emission reduction potentials. For odor and ammonia, these are in line with the potential of exhaust air purification, but with the significant advantage that reductions are implemented and addressed directly in the animal housing area.
A significant portion of these potential improvements stems from the feces-urine separation system, . Multiphase feeding and the newly integrated underfloor air supply system with cooling function in summer and preheating of the supply air in winter further contribute to emission reduction.
Numerous stables have already been built according to this new concept or are currently under construction.

In conversation with Dr. Andreas Steinwidder Ing. Eduard Zentner talks about the results of the largest Austrian research project on pig emissions and the potential of these findings for pig farmers.
