Mechanical, chemical and spectroscopic analysis of mineralisation rate as methods of bones quality determination in broiler chickens

Different method for bone quality assay: bone strength and elasticity, fourier transform infrared spectroscopy for estimation of mineral/organic matrix ratio and chemical composition of ash in bones of chickens, were used. Values of estimated indices are in clearly relation to kind of bones. In young chickens, the strength and elasticity parameters were significant lower in femur as in tibia. Presented results of mineral/organic matrix ratio and Ca-content in ash of bones stand in negative relation to elasticity (r2 = -0.72; -0.69) and in young broiler chickens measurements of mechanical parameters are for bone quality a informative characteristic.
