Pig data

Engineers at Aarhus University, in Denmark, have developed the first multivariate model not to be sniffed at for obtaining an objective assessment of the odor from pig farms that corroborates human experience. The system, which is based on data from proton-transfer-reaction mass spectrometry (PTR-MS), could be used to verify and validate the implementation of odor-remediating systems put in place by proprietors to make the local environment more pleasant for workers and neighbors alike. Air filters and alternative porcine housing design are possible technical solutions to the odor issue, but assessing their effectiveness currently relies on the rather subjective and human nose. A technical assessment that correlates with agreed levels of odor would provide a stronger business and legal footing.
