Survey of Salmonella populations from swine waste-treatment technologies

02-May-2011
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.

Netherlands - Pig-farming sector has efficient production, but manure results in high costs

24-Mar-2011
The Dutch pig-farming sector is operating within a competitive European market, and production costs play an important role in the sector’s competitiveness. At €1.41 per kg of slaughter weight in 2009, the Netherlands’ production costs are fairly average compared with those in rival countries within Europe. However, Dutch pig farmers pay a relatively high price for the disposal of manure: 5% of the production costs.

Farming systems and environment: Effects of available surface on gaseous emissions from group-housed gestating sows kept on deep litter

15-Nov-2010
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?

European Union - EFSA: Pre-assessment of environmental impact of zinc and copper used in animal nutrition

03-Nov-2010
Copper and zinc are routinely used as additives in feed for livestock and aquaculture farming. During their use as feed additives, it is inevitable that Cu and Zn will be released to the environment. Under Regulation (EC) 1831/3003 (EC, 2003), in order to protect human health, animal health and the environment, feed additives should undergo a safety assessment through a Community procedure before being placed on the market, used or processed within the Community. This project therefore assessed the environmental impact of Cu and Zn arising from use as additives in feed for livestock and aquaculture animals.
