In previous projects on the wooden breast (WB) phenomon (very hard breast muscle tissue with infiltration of fat and connective tissue) we have shown that by subjective palpation of the muscle it is possible to divide WB into 3 separate groups: no WB, mild WB and severe WB (Dalsgaard et al. 2017, Int. J. Food Sci. Tech. 53, 1744). We have also shown that it is possible to separate these three categories by metabolite profiling (metabolomics).
By using the subjective scoring method (using metabolic profiling as reference) we have analysed the frequency of WB at a commercial poultry farm. Frequencies was determined over a two year period in four stables of which two stables were ventilated according to the CO2 level (stable 1 and 4). Stable 2 had a slightly increased CO2 level in 2017 but there were no differences in 2018 (in 2018 the farmer had increased the ventilation in stable 2 and 3 and build an outside area for all houses which was open from production day 21).
The two houses without CO2 controlled ventilation had a higher frequency of WB in 2017 (especially stable 2), whereas the adjustments the farmer conducted between 2017 and 2018 in relation to ventilation seemed to correct this. The observed tendencies of a possible CO2 effect demand a more systematic investigation before we can recommend the farmers to increase ventilation since it increases the production costs. The aim of this project is to investigate the influence of CO2-level in controlled research-stables during broiler production on the frequency of WB development.
