Abstract
  1. The objective of this study was to evaluate the prediction potential of a computer tomography (CT) data collection protocol for determining total body composition used for analysis of tibiotarsal bone quality features. 2. The CT image acquisition was performed on 54 healthy TETRA SL genotype laying hens at 90 weeks of age as well as in the 69th week of the egg production period in vivo and their tibiotarsal bones, ex vivo. 3. Breaking strengths and ash content of the tibiotarsal bones were estimated based on the calculated mineral density of skeletal and tibiotarsal bones by means of CT with an estimation accuracy R 0.963 and 0.975, respectively. 4. In conclusion, the current investigation demonstrated that the acquisition protocol of CT for total-body composition analysis has a good potential for measuring the mineral status and breaking strength of the reference bone in laying hen.
摘要

  1. 本研究的目的是评估计算机断层扫描（CT）数据采集方案在确定用于分析胫骨骨质量特征的总体身体成分方面的预测潜力。

  2. 在 90 周龄以及产蛋期的第 69 周，对 54 只健康的 TETRA SL 基因型蛋鸡进行了 CT 图像采集，采集的对象包括体内和体外的胫骨。

  3. 通过 CT 计算出骨骼和胫骨的矿物质密度，分别对胫骨的断裂强度和灰分含量进行了估计，估计的准确性分别为 R 0.963 和 0.975。

  4. 总之，本研究表明，用于全身成分分析的 CT 采集方案在测量参考骨的矿物质状态和断裂强度方面具有良好的潜力。
