This study will provide an effective and practical way of controlling H2S emissions from swine barns. It will contribute to mitigating the health and environmental concerns associated with H2S and thus enhance the acceptability and sustainability of the swine industry.

This paper describes a new model to estimate NH3 emissions from the swine sector, relying heavily on a recent survey of swine producers to determine the present N and manure management practices.

Continuous measurements of ammonia and greenhouse gas were achieved on exhaust air from two fattening rooms differing by the type of floor (totally slatted vs partially slatted floor) and the ambient temperature. Temperature was regulated at 18°C in the room with partially slatted floor (room CP18) and 24°C in the room with fully slatted floor (CI24).

The aim of this study was to investigate the influence of the incorporation of 20% of three raw materials rich in fibre (dried distiller's grain solubles, sugar beet pulp and oily rapeseed cake) on animal growth performance, nitrogen and carbon excretions, and ammonia volatilisation and methane production from effluents.

This study aims to compare emissions of pollutant gases (NH3, N2O, CH4, CO2) from gestating sows kept on straw based deep litter depending on the space allowance and the floor type.

The extent to which early-life environment impacts on microbial diversity of the adult gut and subsequent immune processes has not been comprehensively investigated thus far. We addressed this important question using the pig as a model to evaluate the impact of early-life environment on microbe/host gut interactions during development.

The in vitro method may be a useful tool to predict the potential NH3 emissions of the different feed ingredients
