This POWER Practice Abstract recommends the use of automatic scrapers for reduced ammonia emissions, which remove manure daily or several times per day if needed. Daily scraping of the toilet area during the summer considerably decreases ammonia emissions, compared to scraping 1-3 times a week, since a dry and clean area has hardly to no detectable ammonia emissions.
EPrint Type:
Practice tool
What problem does the tool address?:
The greatest environmental impact from pigs housed in stables with access to a concrete outdoor run is related to the risk of high ammonia emissions from excretions in the outdoor run. Ammonia emissions increase exponentially with higher temperatures.
What solution does the tool offer?:
A more frequent removal of manure from the toilet area reduces ammonia emissions and thereby reduces the environmental impact of organic pig production. Automatic scrapers on the outdoor toilet-area give farmers the possibility to increase scraping frequency, while reducing the workload.
