Background

The breaking strength of chicken bones is often used as a measure of a flockā€™s nutritional health, especially with regard to dietary Vitamin D and calcium as well as the ratio of calcium to phosphorous intake. Bone strength can also be a measure of nutritional feed uptake and a useful indicator when trying to optimize feed programs. This study compares the force required to break chicken bones purchased at the same retail outlet from two commercial sources. The meat was cut from raw drumsticks and the bones were allowed to achieve room temperature. The bones were then flexed to fracture on a TA-92 Three Point Bend rig using a TAXTPlus Texture Analyzer.
