Infrared thermometry (IRTM) is a noncontact method to measure temperature. The purpose of this study was to compare rectal temperature and IRTM in healthy anesthetized swine, with the hypothesis that IRTM would be an accurate, noninvasive alternative for rectal temperature measurement. Two groups of female Yorkshire-cross swine (n = 14 and n = 12) were sedated with Tiletamine–zolazepam (0.5 mg/kg) for blood collection during a routine physical examination. While sedated, rectal temperatures were measured using a SureTemp Plus 690 (Welch Allyn) and IRTM measurements were taken using a FLIR E5 thermal imaging camera. The 2 anatomic sites used for thermography measurements were the area surrounding the eye and the neck at the base of the ear. The distance from the imaging camera and the animal during IRTM measurements was 24 to 32 inches, a distance that would allow camera access in a standard swine enclosure. The infrared imaging camera's surface temperature measurement exhibited a proportional bias when compared with the rectal temperature. All rectal temperature measurements were between 98.7 °F to 101.3 °F, with a mean temperature of 100.4 °F. IRTM tended to underestimate rectal temperatures at lower values, and overestimate rectal temperatures at higher values by approximately (+) or (-) 0.8 °F of rectal temperature. Infrared thermometry can provide a quick noninvasive assessment of the body surface temperature, without the need for animal handling or restraint, but should not be considered an accurate replacement for rectal temperature measurement.

This study was conducted to determine the physiological response of acute heat stress in Kampung Unggul Balitbangtan (KUB) and Walik chickens with four different HSP70 gene haplotypes (H1', H1, H2, and H3). Acute heat stress is carried out at 35°C for one hour. The data was analyzed based on rectal temperature measurements, distribution of body surface temperature (head, neck, body, and leg area), hormone levels (corticosterone and triiodothyronine), and time of panting. Body surface temperature is detected using infrared thermography. The results showed that haplotype H1 Walik chicken is more susceptible to heat stress based on the rectal temperature. In contrast, H1' haplotype Walik chicken released more heat through the body surface in the leg area. Keywords: heat stress, hormone, KUB chicken, infrared thermography, walik chicken

The present study aimed to gather basic information on measuring body surface temperature (BST) of cattle by using infrared thermography (IRT) and find out whether BST measurement is a useful method to detect thermal balance of livestock. Twenty-seven Hanwoo steers were examined in a field trial. The BST of five body regions (eye, nose, horn, ear, rear) was measured five times daily, with three replicates, during 3 days each season. Body surface temperature of cattle is directly affected by ambient temperature and humidity, and showed different ranges for each region. The BSTs of nose, horns and ears were significantly (P < 0.05) lower than those of eyes and rear area. Rear-area BST was significantly lower than eye-area BST when the ambient temperature was low (P < 0.05). Eye BST (EBST) was highest (P < 0.05) and the least variable of all BSTs measured. Therefore, the eye area of cattle was the most thermostable part of the body. There were significant (P < 0.05) differences among seasonal EBSTs of steers. The EBST range was highest in the summer (37.9–42.2°C), followed by autumn (34.3–37.4°C), spring (33.8–36.5°C) and winter (29.8–32.6°C). During extreme cold, EBST showed a large standard deviation. During conditions of extreme heat, EBST was above the average body temperature of cattle. The results of the present study indicated that BST well reflects the thermal circumstances surrounding animals and may be used as one of the effective tools for precision cattle farming.

his study aims to assess the physiological response through body surface temperature of Brahman Cross beef by giving different rest periods. This study used 24 Brahman Cross cattle in several slaughterhouses in West Java. Observation of microclimatic conditions includes temperature, humidity, THI (temperature-humidity index). Data collections of livestock body surface temperature was carried out when the cattle arrive at the slaughterhouse, while they are in the holding pen and the restraining box. Comparative tests were carried out on the surface temperature of cows under different conditions using a completely randomized design (CRD). This study showed that the body surface temperature was still in the normal range, between 30.89-36.75 °C. Analysis of variance showed that different rest periods had a significant effect  (P <0.05) on body surface temperature change in the eye area in the three pre-cutting stages. Providing a 24 hours rest period resulted in lower stress response in livestock.

Abstract Background As dairy herds increase in size, close monitoring of health becomes a necessity, but this is expensive and labour-intensive. Early detection of febrile diseases is essential for economical and welfare reasons and to prevent the spread of disease. The goal of this study was therefore to evaluate a mobile, non-invasive technique for measuring the body temperature of cows that precludes the need for restraint of the animals. An infrared thermographic imaging camera installed on a smart phone was used to measure the surface temperature of cows. In experiment 1, a metal block heated to defined temperatures was used to obtain infrared thermographic measurements. The accuracy of measurements made at different distances from the block and at two different ambient temperatures was determined. In experiment 2, non-febrile cows in a tie-stall barn underwent infrared thermographic imaging, and the body regions with the highest correlations between thermographic and rectal temperature were identified. In experiment 3, thermographic measurements were made in febrile and neighbouring non-febrile cows.Results In experiment 1, the thermographic and true temperatures of the block had the strongest relationships at 0.5 and 1.0 m (r = 0.98). In addition to distance, the ambient temperature had a significant effect on the measurements. In experiment 2, the thermographic measurements at the muzzle (r = 0.28), the eye (r = 0.37) and the medial canthus (r = 0.27) had the strongest relationships with the rectal temperature in non-febrile cows. After correcting the thermographic measurements with the mean difference between thermographic and rectal temperatures of the non-febrile cows, sensitivities of 88, 90 and 82%, respectively, were calculated for thermographic measurements at the muzzle, eye and medial canthus in febrile cows in experiment 3. The corresponding specificities were 6, 23 and 32%.Conclusions Based on the low specificities of the infrared thermographic measurements, the thermographic imaging camera has limited usefulness for the mass screening of dairy cows for febrile conditions. Cattle falsely identified as febrile need to be separated, caught and re-examined, which causes unnecessary stress to the animal and increases labour input.

Abstract. The aim of this study was to evaluate whether an infrared thermometer, a pyrometer, could detect the body surface temperature in the orbital area of gilts without contacting them. Furthermore, it was tested whether an increase in the gilts' temperatures could be detected. Therefore, fever was induced. During 11 trials, 43 German Landrace gilts were injected with either a Porcilis AR-T DF (Intervet International B.V., Boxmeer, Netherlands) vaccine or 2 ml of 0.9 % NaCl. A commercial temperature logger (TRIX-8, LogTag Recorders, Auckland, New Zealand) was placed in the vagina to record temperature data every 3 min. The pyrometer (optris cs, Optris, Berlin, Germany) was aimed at where the orbital area of the gilts would be. While they were drinking, temperature measurements were done in that site by the pyrometer. Time periods from 0.25 to 6 h were analysed. Considering the 0.25-h period, a positive correlation (ρ=0.473) between temperatures of the logger and the pyrometer was found for 15 of 39 gilts. The longer the chosen measuring period was, the fewer animals showed a significant correlation between the two temperatures. In contrast to the vaginal logger, the pyrometer cannot detect an increase in the body temperature in all fever-induced gilts. In conclusion, a pyrometer cannot detect the body surface temperature reliably. An increase in the body surface temperature over a short time period (on average 5 h) could not be detected by the pyrometer. The temperature increase measured using the pyrometer was too low and time-delayed compared to the temperature detected by the vaginal logger.

Background At present, infrared (IR) imaging is used both as a non-invasive and a non-ionizing technology. Using an IR camera, it is possible to measure body surface temperature in order to detect tumors and malignant cells. Tumors have a high amount of vasculature and an enhanced metabolism rate, which may result in an increase in body surface temperature by several degrees above its normal level.

Peripheral Blood Circulation

Peripheral artery disease (PAD) is becoming a serious health problem of present times. It appears crucial to explore therapies that might help to restore blood flow or increase tissue oxygenation. The most effective methods of detecting early-stage changes in blood circulation in the extremities need to be identified. The aim of this study was to identify the effect of carbon dioxide (CO2) bathing on peripheral blood circulation measured by thermal imaging among patients with risk factors of PAD and ankle–brachial index (ABI) in the normal range or ABI indicating some or moderate arterial disease (ABI > 0.5). The correlation between surface temperature change and PAD-relevant characteristics was also examined. Forty-six patients who were over 65 years old who had a minimum of two additional PAD risk factors were recruited. A series of ten dry CO2 baths was performed. Thermal images were taken before and after the intervention. The CO2 therapy caused a significant change in the body surface temperature of many body areas. Numerous moderate correlations between temperature change and health-related characteristics were identified. Therefore, patients with PAD risk factors could benefit from CO2 therapy. Improvements in blood flow change the body surface temperature, and these changes could be successfully detected by thermal imaging.

Predicting the onset of calving is important for the prevention of stillbirths. This study aimed to investigate whether using body-surface temperature and number of steps at the time of calving could be used to predict calving time. Three heifers and 4 cows of the beef cattle variety were used in this study. All animals were housed in calving pens measuring 4.2 × 3.6 m each. Body-surface temperature was recorded using a sensor that was fixed ventrally to the body of the tail head (NIAH, NARO, Tsukuba, Japan). The number of steps the beef cattle took was measured using pedometers (Gyuho, Comtec, Miyazaki, Japan), where each 10 steps resulted in 1 count. The temperature sensors and pedometers were placed on the animals for at least 10 days before the estimated date of delivery. Body-surface temperature and pedometer readings were automatically collected every 2 min and every hour. The data used to predict calving were the means of the body-surface temperature and steps taken, which were recorded from the day the sensors were mounted until 1 day after calving. All data were statistically analysed using t-tests. The mean body-surface temperature before calving was 35.4°C (10 h), which was significantly lower than that recorded 3 days before calving (36.2°C; P < 0.05). The mean body-surface temperature of beef cattle 10 to 6 h before calving (36.0°C) was not significantly different from the mean temperature 3 days before calving. However, from 5 to 1 h before calving, the mean body-surface temperature (34.8°C) was significantly lower than that 3 days before calving (P < 0.05). The mean step number of 101.4 counts, taken 10 h before calving, was significantly increased compared with the mean step number of 44.7 counts 3 days before calving (P < 0.05). The mean step number of 59.7 counts from 10 to 6 h before calving was not significantly different from readings taken 3 days before calving. The mean step number count from 5 to 1 h before calving was 143.1 counts, which increased significantly from readings taken 3 days before calving (P < 0.05). In conclusion, ventral tailhead body-temperature sensors and pedometers can be used to predict the onset of calving in beef cattle. Their body-surface temperature, along with the number of steps taken before calving, decreased and increased, respectively, in the 5 h leading up to calving.
