| Recent findings emphasise the need to improve the animal health status on organic dairy farms in Germany. To assess what are appropriate improvement measures in the farm specific situation and to define health targets, the farmer needs orientation. In this study a competitive benchmarking in relation to production diseases was performed for 60 organic dairy farms. Instead of herd averages, percentages of diseased animals in the herd were used to determine sets of indicators for the four disease complexes udder, metabolism, reproduction, and claws/limbs based on milk recording data. The benchmarking showed that none of the farms performed well (or poorly) in all health areas. Instead, it was shown that each farm possessed its own strengths and weaknesses.... |

| Production diseases, such as metabolic and reproductive disorders, mastitis, and lameness, emerge from complex interactions between numerous factors (or variables) but can be controlled by the right management decisions. Since animal husbandry systems in practice are very diverse, it is difficult to identify the most influential components in the individual farm context. However, it is necessary to do this to control disease, since farmers are severely limited in their access to resources, and need to invest in management measures most likely to have an effect. In this study, systemic impact analyses were conducted on 192 organic dairy farms in France, Germany, Spain, and Sweden in the context of reducing the prevalence of production diseases. The impact... |

| The aim of this study was to assess the prevalence of production disease related indicators on 192 organic dairy farms in Germany, Spain, France and Sweden. The following indicators were used: raised somatic cell count (>100,000 cells/ml, subclinical mastitis), high fat/protein ratio (risk of ketosis), low milk fat (risk of acidosis), prolonged calving interval, clinical lameness, and mortalities of calves and cows. Prevalence of the assessed indicators varied widely between farms and countries. The median prevalence (interquartile range) were 51.3% (15.4) for subclinical mastitis, 10% (7.7) for risk of ketosis, 3.2% (4.7) for risk of acidosis, 42% (20.7) for prolonged calving interval, and 14.2% (20.4) for clinical lameness. The incidence risk of... |

| Production diseases (PDs) emerge from complex interactions between a multitude of variables. In order to prevent and control PDs, measures need to be taken that are likely to be effective in the farm context. In this study, an impact analysis was performed on 60 organic dairy farms in Germany to assess the relationships between 13 system variables and to determine factors with a large impact on PDs. Direct impacts were estimated during a round-table discussion between farmer, veterinarian and advisor using an impact matrix. Indirect impacts were computed and evaluated by graph analysis. Across farms, feeding, hygiene, and treatment had the highest direct impact on PDs, whereas knowledge and skills, herd health monitoring, and dry cow management were... |

| Organic farming is based on the four principles health, ecology, fairness and care, and is governed by EU regulation 834/2007. The question leading to this research was whether these provisions are sufficient to ensure good animal health. Prevalences of production diseases in 192 organic dairy farms in France, Germany, Spain and Sweden were assessed based on routinely collected herd data and locomotion scoring. Herd-level indicators were determined for udder health, metabolism, reproduction and lameness. The median (min - max) prevalence of subclinical mastitis was 51.3% (18.9 - 94.2) and 14.2% (0 - 79.2) of the animals were lame. Prevalence of subclinical ketosis was 10% (0 - 45) and 42% (4.3 - 90.5) of the animals had a prolonged calving interval.... |
