This study aimed at validating the anatomical sites for the measurement of infrared (IR) body surface temperature as a tool to monitor the pigs’ response to handling and transport stress. The selected anatomical sites were the neck (infrared neck temperature—IRNT), rump (infrared rump temperature—IRRT), orbital (infrared orbital temperature—IROT) and behind ears (infrared behind ears temperature—IRBET) regions. A total of 120 pigs were handled from the finishing pen to the loading dock through a handling test course. Two handling types (gentle vs. rough) and number of laps (1 vs. 3) were applied according to a 2 × 2 factorial design. After loading, pigs were transported for 40 min and returned to their home pens. Animal behavior, heart rate, rectal temperature and salivary cortisol concentration were measured for validation. Increased IR body temperature, heart rate and salivary cortisol levels were observed in response to rough handling and longer distance walk (P < 0.05 for all). The greatest correlations were found between IROT and IRBET temperatures and salivary cortisol concentration at the end of the handling test (r = 0.49 and r = 0.50, respectively; P < 0.001 for both). Therefore, IR pig’s head surface temperature may be useful for a comprehensive assessment of the physiological response to handling and transport stress.

ABSTRACT This study aimed to evaluate the effect of thermal stress on the physiological and metabolic parameters in laying hens and the microbiological quality of eggs. The experiment was performed with 50 Rhode Island Red hens in the initial laying phase, under standard diet, lodged in 20 m² stalls under controlled temperature, for 30 days. The laying hens were randomly divided into two groups: G1 - the control group, which contained 10 hens exposed to the temperature of 17 ºC; G2 - the treatment group, which contained 40 hens exposed to the temperature of 30 ºC. The physiological parameters evaluated were: cloacal temperature, body surface temperature, heart rate, respiratory rate, and weight. Biochemical tests included total protein, albumin, globulin, and glucose. The group subjected to thermal stress showed lower body weight, increased heart rate, a slight increase in the respiratory rate, and increase in body surface temperature when compared with the control group (P < 0.05), although no significant differences were observed regarding cloacal temperature. As for the metabolic parameters, the treated group showed an increase in total proteins and globulins compared with the control group (P < 0.05), while albumin remained at basal levels. Additionally, hypoglycemia was observed in the treated group. Samples from egg shells and yolk were subjected to the analyses for the detection of Salmonella spp. These microorganisms were not detected amongst the egg samples.

Objective: To study the changes of body surface temperature of Taekwondo athletes during overload training, and provide new ideas and means for athletes to evaluate their body response after overload training. Methods: The infrared thermography technique was used to monitor the body surface temperature of the chest and abdomen of the Taekwondo athletes, and the changes of body surface temperature were observed. The experiment used Beckman automatic biochemical analyzer to determine creatine kinase (CK) index. The experiment used the RPE scale to test the self-fatigue sensation. On the training day, the training starts at 9:00 am every day and the training is completed in 2 hours. The training starts at 14:00 in the afternoon and the training is completed in 2 hours. The morning training requires a minimum heart rate of 130 beats/min, and keeps it for more than 30 minutes. The training end time is 11:00; afternoon training requires a minimum heart rate of 170 beats/min, and maintained for more than 30 minutes, the training end time is 16:00. Results: The athletes’ sports injury parts increased significantly after exercise, which can indirectly reflect the athlete’s physical fatigue reaction state after overload training. Body surface temperature has a good consistency with creatine kinase (CK), heart rate, and body function response, indicating that body surface temperature values can replace creatine kinase (CK), heart rate, and self-physiological response, indicating that infrared thermography can be accurate. The physiological response status after overload training was assessed. Conclusion: The thermal imaging camera can accurately identify and analyze the injury and physiological response status of athletes. Infrared thermography studies show that the body surface temperature of athletes has a certain correlation with (CK); the body surface temperature and physiological fatigue response of athletes have certain Correlation law; the body surface temperature of the athlete has a correlation with the heart rate; the body surface temperature of the athlete’s sports injury site after the sports injury is significantly increased, which indirectly reflects the physical fatigue response of the athlete after overload training.

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.
