The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions.

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.

Bamboo vinegar may improve digestibility, growth performance and meat quality in finishing pigs.

The feed composition may have a marked effect on sulphur excretion, with a specific contribution of some feedstuffs with high inorganic sulphur content.

Maize DDGS may present a viable option to substitute a premium feed ingredient in growing–finishing pig diets.

A mathematical model serves as a tool to study phosphorus digestibility for different feedstuffs and feeding strategies.

A combination of dietary crude protein and P reduction with added phytase is the key to optimize pig production efficiency, while minimizing their environmental impacts.

This study was conducted to investigate the effects of incorporation into pig diets of 20% of different co-products from the biofuel industries on animal growth performance, on N and carbon C excretions, and on the subsequent ammonia volatilisation and methane production during the storage of slurry.

Under ad libitum feeding, a low crude protein amino acid supplemented diet can reduce N excretion in manure with no impact on animal growth.

Offering a purified source of β-glucans resulted in beneficial reductions in odorous volatile fatty acids in the distal gastrointestinal tract and in excreted manure, and may reflect improvements in N digestibility.

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.

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.

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.

Dietary supplementation with soybean hulls and metal amino acid chelated minerals may reduce noxious gas emissions during growing fattening period
