Intraobserver repeatability for a standardized protocol to quantify keel bone damage in laying hens using discrete and continuous radiographic measures.

ABSTRACT: Sternal carina damage (keel bone damage, KBD) is an important welfare concern for laying hen producers and backyard flock owners. Quantitative radiographic measures of KBD severity are helpful for researchers who study causes for this problem and the effects of novel interventions. The objectives of the current retrospective secondary analysis study were to develop and test intraobserver repeatability for a standardized protocol to quantify three categories of radiographic KBD using open-source image analysis software and discrete and continuous variables. The standardized protocol was developed and evaluated using triplicate measurements of 470 keel bone radiographs that had been previously acquired for a prospective study. Intraobserver repeatability was assessed using intra-class correl
