Description

The dataset contains x-ray images of birds (laying hens) that were generated during the research project funded by Svenska Forskningsrådet Formas (2019-02116). The project aimed to develop a digital tool to assess bones of laying hens using x-ray imaging. The dataset contains a total of 1,116 images, of 168 birds, each bird was x-rayed several times: 3-5 times during their life, 1 time post-mortem, and 1 time for its dissected tibia and keel bones. All images are in JPEG format. All images are named with informative codes indicating bird id, date and time of x-raying, whether the image for live or postmortem x-raying. More details are provided in the attached README file.

Study design

Observational study

Description of study design

Each bird was x-rayed several times: 3-5 times during their life, 1 time post-mortem, and 1 time for its dissected tibia and keel bones. The exact number of images per each bird is tabled in "number_of_images_per_bird.txt"
The experiment was basically on 200 bird, but some birds (e.g. with ID 002) have been excluded form the x-raying for some reasons, e.g. they lost their ID tag during the experiment or get died.

Data collection

Mode of collection: Field/Intervention experiment
Description of the mode of collection: Birds were tagged with unique IDs in a commercial farm, and x-rayed (using bird restraint and portable X-ray machine) on farm condition at 16, 29, 42, 55, 86 weeks of age. Bird were also also x-rayed post-mortem for their whole-body and dissected bones.
