Big Dutchman Improved Odor Control has been tested in four separate tests to evaluate the capacity of the product in reducing odours and liquefying the organic waste fund in the slurry. Visible changes in the manure could be observed and analysis done showed that the product would bring liquefaction of hog manure.

No real analysis is done on the odour at the exception probably of a qualitative evaluation for which no results are presented. This test was done only in two swine buildings, a treated one and a non-treated one, the control. This is not sufficient to be able to draw conclusion.
