英文文献摘要：
Sluggish growth in per capita consumption and a downward pressure on beef price at the farm level has required producers to raise cattle that precisely target the meat attributes desired by consumers. Ultrasound technology can help farmers to produce a carcass with an optimal mix of marbling and muscling, and external fat. The results of this study show a high level of accuracy of ultrasound technology in predicting carcass attributes. An estimated hedonic regression model shows that the carcass attributes are reflected on the implicit beef price. Ultrasound technology helps producers to produce carcass with the desired attributes, thus obtain a higher price.

人均消费量的缓慢增长和农场层面牛肉价格的下行压力，要求生产者饲养的牛要精确地瞄准消费者所需的肉质。超声波技术可以帮助农民生产出具有大理石花纹、肌肉和外部脂肪的最佳混合的胴体。本研究的结果表明，超声技术在预测胴体属性方面具有很高的准确性。一个估计的享乐回归模型表明，胴体属性反映在隐含的牛肉价格上。超声波技术帮助生产者生产出具有所需特性的胴体，从而获得较高的价格。
