“Do remove pig manure regularly as well as completely – and preferably remove the urine separately.” That, in short is the recommendation given by researchers of Wageningen University & Research in the Netherlands.
Commissioned by the Netherlands Ministry of Agriculture, Nature and Food Quality, the researchers investigated which measures could be taken by pork producers to reduce emissions integrally and at the source. Removing manure to a closed storage space can reduce the pig house emissions considerably, they found. The report, called ‘Measures at the source to reduce emissions from existing pig houses’ was published only in Dutch.
Especially the combination of measures could lead to a considerable reduction of several types of emissions at the source. Included are emissions of both ammonia, odour as well as dust particles.
