Improving intra- and inter-observer repeatability and accuracy of keel bone assessment by training with radiographs

Assessing keel bone damage reliably and accurately is a requirement for all research on this topic. Most commonly, assessment is done on live birds by palpation and is therefore prone to bias. A 2-day Training School of the COST Action “Identifying causes and solutions of keel bone damage in laying hens” with 16 participants of variable experience was held where palpation of live hens was followed by consulting corresponding radiographic images...
