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

The funnel slurry system can lower emissions of both ammonia, odour and methane.

Dehydrated orange pulp may become a sustainable feed ingredient for 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.

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 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.

Use of coated proteases in sorghum soybean based diets for growing pigs may improve nitrogen retention and reduce nitrogen content in manure.

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.

The results confirm that a full removal capacity for doxycycline cannot be reached through the long-term storage of farm fertilizers.

This study used oxytetracycline (OTC) as a model antibiotic to study antibiotic degradation behavior in manure under the above two OTC addition methods.

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

The results obtained at the commercial growing-finishing farms show that in uncontrolled conditions the water disappearance and manure production are significantly influenced by the drinker type.

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.

Daily multiphase feeding may be a useful tool to reduce nutrient excretion in manure in growing-finishing pigs.

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