Multiphase feeding on performance, body composition, nutrient excretion and feed costs in pigs
Daily multiphase feeding may be a useful tool to reduce nutrient excretion in manure in growing-finishing pigs.

Protease and xylanase on growth performance, nutrient digestibility, and manure odour
Xylanase reduce gaseous emissions and can moderate the odorous impact of pig manure.
Fate of antimicrobials and antimicrobial resistance genes in simulated swine manure storage
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 impact of reducing straw supply on ammonia, GHG and odours emissions by fattening pigs raised on deep‐litter
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 supplementation on growth performance, digestibility and other parameters in finishing pigs
Bamboo vinegar may improve digestibility, growth performance and meat quality in finishing pigs.
Investigating sulphur content in pig slurry using a nutritional approach
The feed composition may have a marked effect on sulphur excretion, with a specific contribution of some feedstuffs with high inorganic sulphur content.
Growth performance, nitrogen, and phosphorus excretion of pigs fed with incremental levels of DDGS
Maize DDGS may present a viable option to substitute a premium feed ingredient in growing–finishing pig diets.
Modeling the fate of dietary phosphorus in the digestive tract of growing pigs
A mathematical model serves as a tool to study phosphorus digestibility for different feedstuffs and feeding strategies.
Dietary crude protein and phytase-xylanase supplementation of wheat grain based diets affect energy metabolism and enteric methane in growing finishing pigs
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.
Effect of biofuel co-products in pig diets on the excretory patterns of N and C and on the subsequent ammonia and methane emissions from pig effluent
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.
Reduction of greenhouse gas emission from swine manure by using a low-protein diet with synthetic amino acids
Under ad libitum feeding, a low crude protein amino acid supplemented diet can reduce N excretion in manure with no impact on animal growth.
The effect of introducing purified β-glucans to a wheat-based diet on total tract digestibility and gaseous manure emissions from pigs as compared with consumption of a β -glucan-rich, barley-based diet
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.
Survey of Salmonella populations from swine waste-treatment technologies
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.
Impact of temperature control strategies on animal performance, gas emissions and energy requirements for grower‐finisher pigs
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.
Farming systems and environment: Effects of available surface on gaseous emissions from group-housed gestating sows kept on deep litter
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?
Control of hydrogen sulphide emissions from swine barns using nitrite and molybdate: effect of manure age
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.
