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

Dehydrated orange pulp may become a sustainable feed ingredient for finishing pigs.

Feed practices have changed and concentrations of some elements may now be lower. Phosphorus concentration decreased up to 36%, concurrent with introduction of phytase. Most trace elements also decreased, but Zn doubled in nursery manure over 20 yr.

Dietary B. licheniformis and B. subtilis supplementation may reduce noxious gas emissions in growing pigs.

The purpose of this study was to investigate the combined effect of biofilter media depth and moisture content on removal of gases from a swine barn.

The effect of aerating pig slurry during 2 min every 6 h was tested. Aeration increased slurry pH by 0.7 units and NH3 emissions by 20%. CH4 emissions decreased by 40% and no significant N2O emission was detected.

This trial showed the advantage, in an environmental point of view, to use 15% drainage openings on the solid part of partly slatted floors in pens for group-housed gestating sows.

Dietary phytogenic feed additive supplementation may reduce greenhouse gas emission in growing pigs without affecting performance.

Deep-litter system composed of 60% sawdust and 40% rice husk was the most suitable with regard to reduction of environmental pollution.

Orange pulp and carob meal fibre could decrease NH3 y CH4 emissions from slurry.

Keeping group-housed gestating sows on partly straw bedded floor with permanent access to the concrete feeding stalls compared to fully straw bedded floor did not significantly influence animal performance and NH3-emissions, and decreased CO2eq-emissions.

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

Fermented grains reduce faecal noxious gas emission of growing pigs but has variable effects on growth performance and nutrient digestibility.

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 effects of two types of litter (straw and sawdust) and two feeding systems (dry and liquid) on nitrogenous (NH3, N2O and N2) and carbon emissions (CH4 and CO2) were determined in growing pigs.

The objective was to study effects of decreasing CP concentration on CH4 production, C retention efficiency and performance by finisher pigs.
