Heinonen M Hameenoja P Saloniemi H Tuovinen V Diagnoses and treatments in health-classified fattening herds rearing pigs all in - all out. Acta vet. scand. 2001 42 365-375. - This study describes diseases encountered medications used and veterinary involvement in all in - all out finishing herds belonging to one pork production system. The finishing herds had a particular management and housing regime. The pigs originated from health classified farrowing units. Information on 207442 pigs was collected from 595 log books. Altogether 91 of the pigs received no treatments. Four percent of the batches of pigs were given antimicrobial mass medications. The local veterinarian visited the herds on average times during the finishing period and made the diagnoses in more than half of the cases. At least one pig was affected with arthritis or tail biting in more than half of the batches whereas locomotory diseases were recorded in one third of the batches. All other diagnoses were encountered in 1 -13 of the batches. Only a few pigs were treated individually in the affected groups. Antimicrobial drugs were given to 8 and other medicines to of the pigs.
