Dietary supplementation of arazyme and carbohydrolases effectively controls noxious gas emissions and improves health and meat quality in growing-finishing pigs.

A new slurry system with U-shaped slurry trays with flushing or scraping can handle slurry with a high amount of straw and can reduce the emissions of ammonia and odour from pig houses.

Removal of hydrogen sulphide in a biofilter correlates with the presence of fungi. The biofilter removed more than 60% of hydrogen sulphide in the presence of fungi.

Tannins from the quebracho tree can control the production of compounds that cause manure odors, according to studies by U.S. Department of Agriculture (USDA) scientists.

Xylanase reduce gaseous emissions and can moderate the odorous impact of pig manure.

The aim of this study was to determine the impact of a 33% reduction in straw used for bedding on ammonia, GHG and odour emissions.

The feed composition may have a marked effect on sulphur excretion, with a specific contribution of some feedstuffs with high inorganic sulphur content.

In the European Union, the group-housed pregnant sows have to have a minimal legal available area of 2.25 m2/sow. However, it has been observed that an increased space allowance reduces agonistic behaviour and consecutive wounds and thus induces better welfare conditions. But, what about the environmental impacts of this greater available area?
