Computed tomography (CT) parameters, including spiral computed tomography scanning (SCTS) parameters, intramuscular fat (IMF) and mechanically measured shear force were derived from two previously published studies. Purebred Texel (n = 377) of both sexes, females (n = 206) and intact males (n = 171) were used to investigate the prediction of IMF and shear force in the loin. Two and three dimensional CT density information was available. Accuracies in the prediction of shear force and IMF ranged from R² 0.02 to R² 0.13 and R² 0.51 to R² 0.71 respectively, using combinations of SCTS and CT scan information. The prediction of mechanical shear force could not be achieved at an acceptable level of accuracy employing SCTS information. However, the prediction of IMF in the loin employing information from SCTS and additional information from standard CT scans was successful, providing evidence that the prediction of IMF and related meat eating quality (MEQ) traits for Texel lambs in vivo can be achieved.

计算机断层扫描（CT）参数，包括螺旋计算机断层扫描（SCTS）参数，肌内脂肪（IMF）和机械测量的剪切力均来自两项先前发表的研究。 男女均使用纯种特塞尔（n = 377），雌性（n  = 206）和完整的雄性（n  = 171）来研究腰部IMF和剪切力的预测。二维和三维CT密度信息可用。预测剪力和IMF的精度范围为R ² 0.02至R ² 0.13和R ² 0.51至R ²使用SCTS和CT扫描信息的组合分别为0.71。使用SCTS信息无法在可接受的精度水平上实现机械剪切力的预测。但是，使用来自SCTS的信息和来自标准CT扫描的其他信息对腰部的IMF进行预测是成功的，这提供了证据，可以实现体内Texel羔羊的IMF和相关肉食品质（MEQ）特征的预测。
