Protein efficiency is a heritable trait that can be considered in breeding programs to reduce the environmental impact of pig production.

Lowering dietary CP reduces N excretion while maintaining pig performance and carcass composition.

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.

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

The use of digestible rather than total amino acid in diet formulation clearly improve N retention and reduces N excretion.

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.

One of the goals of swine diet formulation is minimizing nitrogen (N) excretion as well as maximizing N retention.

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.

In conclusion, our study confirms that high temperature reduces feed intake, growth performance, and HP.

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.
