In order to determine the possibility of using infrared thermography (IRT) in preventing lameness in dairy cows, the aim of this study was to evaluate temperature variations depending on the lesion presence, measurement points and leg position. The study used about 3 000 IRT records from 60 Holstein cows housed in a free-stall barn. Surface temperature measurements were taken at two regions of the hooves: the region of the coronary band, and the region of the skin up to 2 cm above the coronary band. A highly significant ( = 0.004; 0.006, < 0.01) difference in temperature was observed between healthy and diseased legs at both measurement points. Additionally, a significant ( = 0.029; 0.037; 0.045; 0.012; 0.018, < 0.05) or highly significant ( = 0.004; 0.006, < 0.01) difference in temperature values between the front and rear legs was established for both measurement points, i.e., the coronary band and the skin. Despite confirming the potential applicability of infrared thermography in the detection of lameness, it is crucial to consider the significant influences of the environmental factors, impurities, and animal-related factors.
为了确定使用红外热成像技术（IRT）预防奶牛跛足的可能性，本研究的目的是评估根据病变情况、测量点和腿部位置的温度变化。该研究使用了来自自由牛舍中60头荷斯坦奶牛的约3000条IRT记录。在蹄部的两个区域进行表面温度测量：冠状带区域，以及冠状带上方2厘米处的皮肤区域。在两个测量点，健康腿和患病腿之间的温度差异非常显著（=0.004；0.006，<0.01）。此外，在两个测量点，即冠状带和皮肤处，前后腿之间的温度值存在显著（=0.029；0.037；0.045；0.012；0.018，<0.05）或非常显著（=0.004；0.006，<0.01）的差异。尽管证实了红外热成像技术在跛足检测中的潜在适用性，但考虑环境因素、杂质和动物相关因素的重大影响至关重要。
