Keeping sick children at home In the human world, every parent would know that keeping sick children at home would both ease the recovery and avoid spread of disease to the other children in school. De- spite this basic knowledge about disease prevention and containment, we see in the caretaker’s management of dis- eased pigs, as well as busy parents with sick children, very high risks are taken in order to keep things going. This might explain why 77% of farms are holding pigs back for weaning quality, keep weaned pigs in farrowing room (58%), and al- low some kind of continuous flow after weaning in 48% of farms. On top of that, 74% of herds carry out a risky intro- duction of gilts, without proper quarantine facilities and quarantine time. The key benefit of scoring tools, are not the score in itself. The tool should facilitate behavioural changes that improve pig flow and management, by visualising the risky be- haviours and the transmission patterns of pathogens. The evaluation of management procedures in the app is unique in both the details of evaluation and the feedback format that allows farmers, veterinarians and other advisors to ad- dress and prioritise high risk procedures and the way it vi- sualises the score.
Understanding risky behaviours It is important to mention that the differences between success and failure in risk reduction in biosecurity and man- agement are not determined by the details in a scoring re- port. Improvements are only seen when mistakes and risky behaviours are understood and corrected.
