Strategy for ventilation of stables for broiler production without wooden breast

Project: Research

Description

The aim of this project is to reduce wooden breast in broiler production, minimise quality degradation and maintain consumer acceptance of poultry meat.
I a previous project on different CO2 concentrations during broiler production we were not able to maintain the set high CO2 concentrations during the entire production period due to required ventilation of the stable (heat and humidity in June/July). Thus, the CO2 levels of approximately 2000, 2500 and 3000 ppm, respectively, was only obtained day 4-18 post hatch.
Assessment of wooden breast and white striping show an increased frequency of wooden breast at 2500 and 3000 ppm CO2 and increased frequency of white striping at 3000 ppm CO2, which may indicate that increased CO2 levels in the stable around 1-3 weeks post hatch can initiate a later development of abnormalities including wooden breast. These tendencies will be investigated in the present project by merging CO2 data from the stable environment with wooden breast related quality degradation (frequency) at the slaughter plant - all from the same flocks.
SKOV and Danpo volunteer access to data from the stable and slaughter plant, respectively, after obtaining consent from the producers. Data on CO2 levels during the production period is merged with wooden breast frequency data from the slaughter plant (as determined by AU) at the level of stable and flock. These registrations will reflect fluctuations over the year.
