Comparison of thermal imaging and Rectal temperature in the diagnosis of pyrexia in pre-weaned calves using on farm conditions
Research in veterinary science, 2020Co-Authors: David B. Bell, Alastair Macrae, Malcolm A. Mitchell, C. Mason, Amy Jennings, Marie J. HaskellAbstract:Abstract Measuring core body temperature is used as part of the diagnostic process in assessing the health of animals. Typically in calves, this is carried out using a Rectal Thermometer which can be time consuming, stressful to the calf and is invasive by nature. A non-invasive technique that is gaining recognition is thermal imaging. This study investigated the use of thermal imaging as a technique to assess core body temperature in pre-weaned artificially reared calves. A total of 125 male and female calves had Rectal temperatures measured daily from day 7 until day 40 of life, and at the same time had a thermal image taken of the area around the medial canthus of the eye. A weak correlation (r = 0.28) was found between calf Rectal temperature and thermal image temperature. A multivariable predictive model for core body temperature increased the correlation (r = 0.32) when including the environmental parameters of air temperature (p The results of this study demonstrate the need to take thermal environmental parameters into consideration when using thermal imaging to assess body temperature. However, the results suggest that accurate measures of core body temperature using thermal imaging cannot be achieved under commercial farm conditions. Further research is needed to determine what other factors could be measured to increase predictive ability.

Assessment for predicting parturition in mares based on prepartum temperature changes using a digital Rectal Thermometer and microchip transponder thermometry device.
The Journal of veterinary medical science, 2012Co-Authors: Kenji Korosue, Harutaka Murase, Fumio Sato, Mutsuki Ishimaru, Yoshiro Endo, Yasuo NamboAbstract:Abstract The purpose of this study was to observe the changes in body temperature before parturition using a wireless temperature monitoring device (WTMD) and to evaluate the usefulness of body temperature measurements using a digital Rectal Thermometer (DRT) and a microchip transponder thermometry device (MTTD) for predicting parturition in mares. The body temperatures using a WTMD at 0 hr and -1 hr were significantly different from those at the same time on Days 1-5 (P

assessment for predicting parturition in mares based on prepartum temperature changes using a digital Rectal Thermometer and microchip transponder thermometry device

The body temperatures using a WTMD at 0 hr and -1 hr were significantly different from those at the same time on Days 1-5 (P<0.01). The temperature differences between the morning of Day 0 and at -3 hr, -2 hr, -1 hr and 0 hr using the DRT and MTTD showed a significant drop compared with the temperature differences between the morning and evening of Days 1-5 (P<0.05). Furthermore, when the cutoff value of the temperature differences between the morning and other times was set to ≤0, the sensitivities of the DRT and MTTD in the evening of Day 0 and at -3 hr were 43% and 100% and 71% and 86%, respectively. The results suggested that monitoring the body temperature differences between morning and within 3 hr before the time of parturition is a valuable method for predicting parturition in mares. Conversely, this method would be more useful in predicting parturition when used in combination with other observations such as the mammary gland size and waxing of the teat ends because it has nearly a 20% probability of false-positive results prior to the day of parturition.

Infrared thermal imaging as a method to study thermogenesis in the neonatal lamb
Animal Production Science, 2014Co-Authors: Susan A. Mccoard, Harold V. Henderson, F. W. Knol, S. K. Dowling, James R. WebsterAbstract:The combination of heat generation and reducing heat loss from the skin surface is important for maintaining core body temperature in a neonate. Thermogenesis studies traditionally focus on measurement of core body temperature but not the contribution of radiated heat loss at the skin surface. This study aimed to evaluate the utility of using thermal imaging to measure radiated heat loss in newborn lambs. Continuous thermal images of newborn lambs were captured for 30 min each during the baseline (11−18°C), cold-exposure (0°C) and recovery (11−18°C) periods by using an infrared camera. Core body temperature measured by Rectal Thermometer was also recorded at the end of each period. In all, 7 of the 10 lambs evaluated had reduced Rectal temperatures (0.4−1°C) between the baseline and recovery periods, while three maintained body temperature despite cold exposure. During the baseline period, infrared heat loss was relatively stable, followed by a rapid decrease of 5°C within 5 min of cold exposure. Heat loss continued to decrease linearly in the cold-exposure period by a further 10°C, but increased rapidly to baseline levels during the recovery period. A temperature change of between 20°C and 35°C was observed during the study, which was likely to be due to changes in vasoconstriction in the skin to conserve heat. The present study has highlighted the sensitivity of infrared thermal imaging to estimate heat loss from the skin in the newborn lamb and shown that rapid changes in heat loss occur in response to cold exposure.
