Stakeholders were generally satisfied with the findings but believed the net margin losses for keel bone damage and footpad dermatitis were too high. He stressed that due to the astonishing lack of financial data following a global literature review that the costs had to be estimated from changes in physical parameters. A total of 127 relevant publications were found. Some were simple surveys of disease, and others that explore the impact of disease on productivity compared with control groups, with the im- provements measured in physical terms, such as Feed Conversion Rates (FCR) or bacteria counts.


Disease Nine production diseases were identified for the study, select- ed by scientists working on the project and the importance of the diseases in their respective countries (Finland, Germany,


Poland, Spain and the UK). Around 100 stakeholders were consulted across the production chain, including farmers, vets, abattoirs, hauliers and processors. It covered both clinical and sub clinical information. The nine identified were injurious feather pecking, salpingop- eritonitis syndrome, keel bone damage, footpad dermatitis, tibial dischrondoplasia, clostridiosis, coccidiosis, infectious bronchitis and ascites. The study also looked at mortality rates and weight losses in- curred by the production diseases. Salpingoperitonitis had the highest mortality rate while in terms of weight losses, coccidiosis, tibial dischrondoplasia and footpad dermatitis were the three diseases that fared worst. Scientists also no- ticed a small decrease in quality in the meat being processed. In the laying hen sector, infectious bronchitis had a massive effect on egg numbers, cutting production by a third.
