Development of the ‘animal welfare’ dimension within the Greenwell sustainability assessment model: 2. Data for all production stages andcalculation of scores for the broiler on-farm stage

Samenvatting

Within the Greenwell project, a model will be developed to assess the sustainability(environmental impact, economic impact, animal welfare and health impact) of broiler productionsystems. The present report provides values and variation for the welfare indicators in the differentstages of the broiler production chain (broiler breeders, hatchery, broiler farm and end-of-life stage)based on the Greenwell welfare model for four selected production systems (conventional, DutchRetail Broiler, Better Life one star, organic), if known. These data have been collected by theGreenwell consortium partners or other chain partners in the Netherlands over the year 2017; whereno data were available estimations based on 2018 or 2019 were used. In addition to that, a scoringsystem has been developed to assign a welfare score on a scale between 0 (worst)-100 (perfect) forthe welfare indicators of broiler production on-farm. To this end, a database containing processingplant and hatchery data over 2017 and 2018 has been used. The sum of the scores for the individualindicators presents the total welfare score for a particular broiler flock. Results show the averagewelfare scores for broilers on-farm and the variation within production systems, for conventional,Dutch Retail Broiler and Better Life one star. No data were available to assign scores to organic flocks.
