Under the conditions of this study, finishing environment alters performance, carcass merit, and meat quality of pigs of similar genetic merit. Farms with differing types of finishing facilities should account for finishing environment in the development of their finishing management protocols.

The objectives of this field survey were to evaluate the effects of several promising swine waste-management and treatment technologies on reducing Salmonella presence and populations and to characterize the diversity of Salmonella isolates recovered from the waste streams using serotyping and antibiotic-susceptibility analysis.

From 2012, feeds for organically farmed pigs must consist of 100% organic ingredients. Pea protein concentrate and rapeseed protein concentrate may be attractive high-protein ingredients for piglet feeds. This is the conclusion from research by Wageningen UR Livestock Research into the digestibility and nutritional value of a number of high-protein ingredients for organically farmed weaned piglets.

Castration is notably used to reduce pigs’ aggressiveness towards humans and facilitate handling. However, there are no scientific data to confirm this. We compared entire and castrated male pigs reared in a conventional or an enriched environment.

The reduction of protein levels from weaning till slaughter, in keeping with the current French recommendations to reduce pollution (CORPEN, 2003), was evaluated in a feeding trial.

The objectives of this study were to compare the impact of three control strategies of temperature set point on grower‐finisher pigs and their growth performance, ammonia emissions, and heating energy consumption under Québec conditions.

A total of 16 crossbred (Large White × Landrace) castrated male pigs averaging 30.0 ± 2.5 kg were used in two trials (2 × 8 pigs) to determine apparent nutrient digestibility. The control group received feed mixture consisting of wheat and barley. In the experimental group, 3% proportion of wheat was replaced by sodium humate.

The use of hulless low-phytate barley may improve nutrient digestibly reducing environmental pollution.

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?

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
