Denmark: Decrease in total antimicrobial consumption in pigs

For the first time since 2002, the total antimicrobial consumption in pigs decreased. The decrease in consumption was 5% measured in doses per pig produced (adjusted for export of pigs around 30 kg) compared with the 2009 level, but remained above the 2008 level (by 7%).

DANMAP 2010 report shows that for the first time since 2002, the total antimicrobial consumption in pigs decreased. The decrease in consumption was 5% measured in doses per pig produced (adjusted for export of pigs around 30 kg) compared with the 2009 level, but remained above the 2008 level (by 7%). Over the past decade, the consumption per pig produced has increased by 39% (2001–2010).

The decrease in 2010 was mainly in use of tetracyclines with a reduction of 100.5 tonnes, representing a 5% decrease per pig produced. Also the use of macrolides (2%), aminoglycosides (16%), lincosamides/spectinomycin (7%) and cephalosporins (48%) was reduced. Tetracyclines, macrolides and pleuromutilins mainly used for oral therapy, continued to be the most commonly used antimicrobial agents in pigs throughout 2001–2010.

The overall decrease in consumption was mainly associated with an 11% decrease in prescription for weaning pigs primarily for gastrointestinal infections, but also decreasing prescription for sow herds was observed. The consumption in sow herds (including piglets) decreased by 3% per sow-year, related to a 22% decrease in prescription for gastrointestinal disease.

The decrease in consumption in 2010 was entirely related to the second half of the year, while in the first half of the year, the consumption increased by 8% compared to the same period in 2009. The decrease in use of cephalosporins was related to a voluntary ban by the industry enforced in July 2010. The same month, the “yellow card” intervention was announced with an information letter to part of the pig farmers, representing the farms with the 20% highest consumption per pig . This is a likely explanation for the 13% reduction in the second half year compared with the same period in 2009.
