This abstract helps illustrate the link between antibiotic use and PMWS (circovirus) outbreaks and explains the creation of MRSA st398 and increased veterinary abuse of drugs important to human health.
But still nothing is done either to curb wild dangerous veterinary prescription and cover-ups.
The veterinarians must want to collapse their industry in international disgrace. They are getting there at ever increasing speed.
It’s pretty obvious that you don’t spend money on antibiotics for healthy pigs, the antibiotic usage figures from government sources, when published, expose the enormous numbers of sick pigs being nursed through illness to slaughter.

A retrospective cohort study was performed on 130 pig herds in Denmark, to assess the effect of PMWS on the use of antimicrobial drug. The study comprised 65 herds diagnosed with PMWS during 2003-2004, and matched by the veterinary practitioner with 65 herds free from PMWS. Information on antimicrobial use 1 year before and 1 year after the diagnosis was achieved from the National Prescription Medicine Monitoring Database, VetStat, and summarized on quarter within age group and herd....
... Relative to the unaffected herds, the antimicrobial use in the sow units in the PMWS(+) herds was elevated significantly by 35% in the last quarter and 43% in the fourth quarter before positive diagnosis in the herds (p<0.05). In weaner pigs, the antimicrobial use increased significantly two quarters before, and one quarter after the positive diagnosis, by 68%, 91% and 124% respectively. In weaner pigs, effects were seen of herd size and season. The study support that increased morbidity occur for an extended period prior to the diagnosis of PMWS, both in the sow units and the weaner pig units and further indicate that the syndrome cease after the diagnosis, with a decrease in need for antimicrobial treatment.
