Soft perches in an aviary system reduce incidence of keel bone damage in laying hens.
PLoS ONE, 2015 Keel bone fractures and deviations are one of the major welfare and health issues in commercial laying hens. In non-cage housing systems like aviaries, falls and collisions with perches and other parts of the housing system are assumed to be one of the ...

Genetic variation of keel and long bone skeletal properties for 5 lines of laying hens
Journal of Applied Poultry Research, 2020 Summary: Fractures to the keel bone is one of the greatest problems facing the laying hen industry. With most severe effects observed in non-cage housing, frequencies are expected to dramatically increase as the industry continues transitioning away from

Keel bone damage assessment: consistency in enriched colony laying hens
Poultry Science, 2019 Damage to the keel bone is a major issue in the laying hen industry. The goal of this study was to compare palpation results of live laying hens to digital computed tomography (CT) images, to assess changes in palpation reliability as training and familiarity increased, and to examine keel bone morphology over time.

Research Note: A deep learning method segments chicken keel bones from whole-body X-ray images
Poultry Science: Most commercial laying hens suffer from sternum (keel) bone damage including deviations and fractures. X-raying hens, followed by segmenting and assessing the keel bone, is a key to automating the monitoring of keel bone condition.

The neck of Barosaurus was not only longer but also wider than those of Diplodocus and other diplodocines [PDF]
, 2016 Barosaurus is a diplodocid sauropod from the Upper Jurassic Morrison Formation of the western United States, and is known for its very long neck. It is related to the sympatric Diplodocus, and often thought of as more or less identical except with a ...

Effects of housing, perches, genetics, and 25-hydroxycholecalciferol on keel bone deformities in laying hens [PDF]
, 2017 Several studies have shown a high prevalence of keel bone deformities in commercial laying hens. The aim of this project was to assess the effects of perch material, a vitamin D feed additive (25-hydroxyvitamin D3; HyD, DSM Nutritional Products, Basel ...
