Impact of Drinking Water Sulphate Levels on Gas Emissions and Manure Nutrients
A major environmental concern for the swine industry are odour and gaseous emissions. Sulphur containing compounds are some of the most odourous components of swine. Drinking water quality on air emissions and swine manure nutrients were assessed. Up to 1,800 ppm of sulphate in drinking water had no adverse effects on odour and gas emissions, performance or manure nutrient levels so water treatment is not necessary. There is potential to see an increase in hydrogen sulphide levels during manure handling operations from high-sulphide drinking water so more studies need to be done in this area.
