Pilotstudie: Bewertung der Ammoniakemissionspotenziale von Milchkuhlaufställen bei Kombination mehrerer Minderungsmaßnahmen

The national emission reduction commitments (NEC) require the use of NH3 mitigation measures on livestock farms. In this pilot study, an innovative barn construction project from an EIP Agri project in Baden-Wurttemberg was used as an example to analyse how a combination of measures affects the NH3 emission potential of free stall dairy barns. For this purpose, a method for the evaluation of the NH3 emission potential based on a multiplication of mitigation factors was developed and applied. For the example barn with an exercise yard, a lower emission potential per animal place and year could be determined than for a standard cubicle barn without an exercise yard. However, a reduction of the total emission potential of the example farm compared to the initial situation was not possible due to the doubling of the herd size in the course of the new construction. Nevertheless, the study showed potential for the compatibility of animal welfare and NH3 emission reduction in dairy cow husbandry.
