Abstract

The aim of the present study was to generate thermographic profile of foot region viz. body temperature (BTºC), coronary band temperature (CBTºC), hoof skin surface temperature (HSSTºC) and mean temperature difference (ΔTºC) in Murrah buffaloes (Bubalus bubalis) and its relation with ambient temperature. A total of 60 hooves of lactating Murrah buffaloes (n = 15) maintained in a farm, were monitored once a day continuously for 15 days before evening milking using forward-looking infrared (FLIR) i5 camera. Total of 1125 thermograms were analyzed using FLIR Quick Report 1.2 image analysis software. The mean ± SD (°C) of BT, CBT, HSST and ΔT of all animals throughout the experimental period were 37.39±0.05, 34.93±0.13, 34.16±0.13 and 0.76±0.26 respectively. The CBT was around 0.5 to 1°C higher than HSST. Statistical analysis revealed that ambient temperature is highly and positively correlated with CBT (ºC) (r = 0.95) and HSST (ºC) (r = 0.99), indicating greater influence of ambient temperature on surface temperature of foot region. Therefore, CBT (ºC) and HSST (ºC) have a tendency to follow variations in ambient temperature (R2 = 0.91 and 0.98 respectively). However, significant difference was observed between BT vs. CBT, BT vs. HSST and CBT vs. HSST (ºC). The mean ± SD (°C) of ΔT of all animals, throughout the observation period was 0.96±0.41. A significant difference was observed in ΔT between animals (P<0.001). However, significant difference was not observed in ΔT between days and among four hooves within animal. It is concluded that, to the best of our knowledge this is the first report on baseline thermographic information on BT, CBT, HSST and ΔT differentials for buffalo and its clinical significance in monitoring hoof health and management.

Murrah水牛(Bubalus bubalis)身体和蹄皮表面温度分布的数字红外热成像:初步报告
本研究的目的是建立默拉水牛足部体温(BTºC)、冠状带温度(CBTºC)、蹄皮表面温度(HSSTºC)和平均温差(ΔTºC)的热像图及其与环境温度的关系。采用前视红外(FLIR) 15型摄像机,对某农场的60头哺乳期Murrah水牛(n = 15)在晚间挤奶前进行监测,每天1次,连续监测15天。使用FLIR Quick Report 1.2图像分析软件对1125张热像图进行分析。实验期间所有动物的BT、CBT、HSST和ΔT的平均±SD(°C)分别为37.39±0.05、34.93±0.13、34.16±0.13和0.76±0.26。CBT比HSST高0.5 ~ 1℃左右。统计分析显示,环境温度与CBT(ºC) (r = 0.95)和HSST(ºC) (r = 0.99)呈高度正相关,表明环境温度对足区表面温度的影响较大。因此,CBT(ºC)和HSST(ºC)有随环境温度变化的趋势(R2分别= 0.91和0.98)。然而,BT与CBT、BT与HSST、CBT与HSST之间存在显著差异(ºC)。所有动物在整个观察期内ΔT的平均值±SD(°C)为0.96±0.41。动物间ΔT的差异有统计学意义(P<0.001)。然而,在ΔT中没有观察到天之间和动物四蹄之间的显著差异。结论是,据我们所知,这是关于水牛BT、CBT、HSST和ΔT差异的基线热成像信息及其在监测蹄健康和管理方面的临床意义的第一份报告。
