Effects of dietary benzoic acid and sodium-benzoate on performance, nitrogen and mineral balance and hippuric acid excretion of piglets
Benzoic acid is more effective than sodium-benzoate in piglet’s performance and metabolism.
Effect of litter type and feeding system on ammonia and greenhouse gas emissions in growing pigs
The effects of two types of litter (straw and sawdust) and two feeding systems (dry and liquid) on nitrogenous (NH3, N2O and N2) and carbon emissions (CH4 and CO2) were determined in growing pigs.
Keratinase affects performance and intestinal morphology and ecology of piglets fed diets with different levels of crude protein
Keratinase supplementation has a positive effect on the performance of weanling piglets fed corn-soybean diets.
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.
Effects of type of cereal and fibre level on growth and parameters of the gastrointestinal tract in young pigs
Fermentable carbohydrates as a way to reduce protein fermentation and to promote beneficial microbial populations in piglets fed rice based diets.
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.
The Effect of Dietary Sodium Humate Supplementation on Nutrient Digestibility in Growing Pigs
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.
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?
Farm practices survey and modelling to estimate monthly NH3 emissions from swine production in 12 Ecoregions of Canada
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.
Comparison of ammonia and greenhouse gas emissions from fattening pigs kept either on partially slatted floor in cold conditions or on fully slatted floor in thermoneutral conditions
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).
