Surface temperatures of hoofs of calves given toxic anion fractions of tall fescue were measured with an infrared sensitive camera. These changes expressed in terms of a weighted average coronary band temperature relate to clinical signs of fescue foot. The weighted average coronary band temperature values for control calves given saline solution were 27 to 31 C; those values of test calves given anion fractions of tall fescue were as low as 22 +/- 1 C. Videothermometry provides an independent, permanent, objective measure that is useful in assessing fescue-foot potential of tall fescue fractions by intraperitoneal injection. Videothermometry may also serve as a clinical means for determining progression of the total fescue foot syndrome.
用红外敏感相机测量了给与有毒阴离子组分的高羊茅的犊牛蹄部表面温度。这些以加权平均冠状带温度表示的变化与牛脚叶病的临床症状相关。给与盐溶液的对照犊牛的加权平均冠状带温度值为27至31摄氏度；给与高羊茅阴离子组分的试验犊牛的这些值低至22±1摄氏度。视频温度测定法提供了一种独立、持久、客观的测量方法，可用于通过腹腔注射评估高羊茅组分导致牛脚叶病的可能性。视频温度测定法也可作为确定整个牛脚叶病综合征进展情况的一种临床手段。
