| Health and welfare problems in organic pig production may differ form problems in conventinal pig herds as a result of differences in management. Control of animal health problems in organic herds is affected by the restrictions in medicine use and prophylactic medication as well as by the risk of wildlife contact and difficulties in cleaning and and disinfectin imposed by the access to outdoor areas. To monitor risk factors for diseases and to control these risk factors as a means to prevent diseases, we suggest the implementation of health management based on Hazard Analysis Critical Control Point (the HACCP concept). The development of a HACCP system requires the quantification of risk factors by means of epidemiological studies of alternatively by an... |

| The prevalence of Salmonella shedding was compared in 34 organic, conventional outdoor, and indoor pig herds. Individual faecal and meat juice samples from 30-50 pigs per herd were analysed for presence of Salmonella, and Salmonella antibodies, respectively. We found low levels of Salmonella shedding on farm and at slaughter in organic and conventional outdoor herds compared to indoor pigs. Overall 5,5 % of the pigs were seropositive. The serological test result was associated with Salmonella shedding at slaughter in pigs from conventional systems, but not in organic pigs. The duration of transport did not affect the risk of Salmonella shedding. |

| The health of weaned pigs should be described using several information sources to get an overall assessment of the health state in the herd. In this case study four organic pig herds each fattening between 800 and 3500 pigs per year provided data from clinical examination of a sample of animals, pathological findings at slaughter, post weaning mortality and medicine usage in the herd. Clinical symptoms were present in 8 – 18 % of the pigs, and 2 – 6 % of the pigs showed more serious symptoms of disease. At slaughter 10 – 17 % of the pigs got remarks for pathological lesions, primarily liver spots, abscesses and chronic pericarditis. The post weaning mortality varied between herds, while the usage of medicine was rather low in the herds. The herd health... |
