High animal comfort and low emissions in a new housing system for pigs

The objective of the DBU-funded project “Pig farming without FYM and slurry” is the development of a pig farming system which, on the one hand, significantly reduces environmentally and climate-relevant emissions and, on the other hand, meets the sociopolitical requirements for animal-friendly livestock farming.

The newly developed system is based on the separation of faeces and urine right in the barn using an optimised and automated underfloor manure removal system. The separated urine is quickly removed from the pen and, in addition, is already stabilised in the pen with urease inhibitors (hydrated lime, sulphuric acid, synthetic substances), so that the emission of ammonia is prevented to a great extent.
