Correlation and path analysis of assessment methodologies of bone quality from brown egg layers at final of the production cycle

This study aimed to investigate direct and indirect correlations of methodologies bone quality analysis from brown egg layers, at final the production cycle. Twelve femurs Dekalb Brown laying hens, euthanized 85-week-old, were assessed evaluate breaking strength (BS), Seedor index (SI), mineral matter (MM), calcium (Ca) phosphorus (P) contents, besides cortical (CorD), medullar (MedD) epiphysis (EpiD) diameters. Correlations path obtained with aid SAS® University (p ≤ 0.05). The BS directly represented was compared other methodologies. Greater linear occurred between MM (r = 0.82), Ca 0.72), 0.70). content displayed greatest effect on 0.53). showed a reduced 0.18), effects through 0.44) EpiD 0.15), however, presented great total correlation 0.78). Determination is main methodology associated femur layers productive Because that, this more reliable determine quality.
