Offering pigs a low-P diet from 10 to 100 kg BW lead to reductions in P excretion, however, growth performance and bone mineralization were compromised.
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.
To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts.
The results of the present study suggest that synbiotics exert similar effects with antibiotics on the nutrient digestibility and fecal microflora composition in growing pigs. Moreover, synbiotics can also decrease the fecal noxious gas emission in growing pigs.
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.
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.
