Abstract

The common practice of supplementing pig rations with copper sulphate leads to the excretion of copper in the faeces, producing levels in the slurry as high as 750 ppm. The aerobic biodegradation of pig waste under laboratory conditions has been shown to be progressively inhibited up to 500 ppm of added copper. This concentration is sufficient to prevent reduction in Chemical Oxygen Demand and degradation of soluble nitrogen compounds.
