“…Hoffmann et al (2012) obtained a similar result in the IR thermographic sensing at cow's vulva (37.2°C). Different results have been reported by Stelletta et al (2017) in which IRT at the vulva of Angora goats before lust synchronization is 36.78°C and decreases to 35.40°C at the end of the estrous period. Hoffmann et al (2012) and Talukder et al (2015) reported that vulva temperature was the indicator used to identify changes in body temperature as general features of animals' physiology and health.…”

“…The difference in body temperature measured was due to the difference in the variety of goats used. Simoes et al (2014) and Stelletta et al (2017) reported an increase in vulva temperature during the estrous period until approaching ovulation, and then the vulva temperature decreased at the end of the estrous period. The absolute point of vulva temperature can be affected by an environmental condition such as relative humidity, wind speed, and solar radiation.…”

Infrared thermography (IRT) is an alternative solution that can be applied to replace invasive methods currently used in the monitoring of goats' physiological and hematological parameters. This study was done to compare and correlate the physiological and hematological conditions of young Sapera dairy goats and their correlations with results obtained by IRT. Four young Sapera dairy goats (weight of 26-28 kg) were kept in the individual rearing cage. Skin surface temperature (TS), rectal temperature (TR), body temperature (TB), heartbeat (HR), respiration rate (RR), and IRT at eyes, mouth, nose, legs, left body, right body, vagina, and vulva were monitored from 6 a.m. to 6 p.m. in 2 h intervals. Blood samplings were done at the beginning and the end of the obsevation time. Results showed that IRTs at several body parts were positively correlated with physiological parameters, except for heartbeat. Negatively correlation was observed in hematological parameters. The highest correlation (r = +0.85) was observed in the correlation between the results of the left rear leg IRT on TB. It was concluded that IRT can be applied to examine goats’ physiological conditions especially body temperature<span lang="IN">.</span>

Presently, there is an increased demand for livestock products all over the world which has led to more devotion on improving livestock population. Although goats have been bred for a long time in Korea, but there is not much research conducted on traditional Korean black goat (Capra hircus coreanae) compared to other livestock populations. Mutton consumption has been dramatically changing from medicinal use to edible meat and this trend directs the black goat populations declining and also mutton import quantities are increasing consistently. The present study introduced a new estrus synchronizing technique with subsequent artificial insemination (AI) for Korean black goats to enable crossbreeding with non-native breeds for the small or subsistent farmers. Our data highlighted that, the percentage of motile sperm from the electro-ejaculated samples declined significantly after freezing and melting. In addition, the sperm motility significantly declined with regard to sperm incubation period (0, 5, 60, and 120 min at 37℃) and was negatively correlated (64.2 ± 7.9%, 63.3 ± 5.8%, 49.9 ± 6.3%, and 35.9 ± 7.6%, respectively) in frozen-thawed sperm samples. Moreover, the E2 levels were unchanged even 24 h after controlled internal drug releas (CIDR) withdrawal. But, 48 h and 72 h after CIDR removal, E2 levels increased significantly. These data helps us to consider the two time points for AI; CIDR removal after 24 h, at which E2 decreases, and after 48 h, as the time at which progesterone increases. Additionally, the AI after 48 h of CIDR removal group exhibited significantly higher pregnancy and parturition rates (42.9%) compared to AI after 24 h after CIDR removal 28.6% group. In conclusion, these studies will propose an optimal estrus synchronisation process with subsequent timing of AI and also will promote the Korean black goat breeding industry.

“…Infrared thermography is common practice for different purposes in internal medicine and surgery, particularly as a diagnostic tool in small animals [ 4 , 5 , 6 , 7 , 8 ]. However, in reproduction, there are few reports related to pregnancy diagnosis, estrus detection, mastitis, or to the development of mammary tumors [ 8 , 9 , 10 , 11 , 12 , 13 ]. Infrared thermography in clinical animal andrology is considered in various species and specific information about its use for the definition of a thermal pattern of scrotal surface temperature is present above all in species with a pendulous scrotum [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

This study aimed to describe the thermal variation of external reproductive tracts during ejaculation in relation to sperm quality in dogs. Forty-six adult fertile dogs were monitored using a thermal camera before, during and after the semen collection, taking into account penile and scrotal temperatures as reproductive thermal patterns while eye and perianal temperatures were recorded as complementary thermal patterns of behavioral response. The parameters were classified depending on age (≤4 years and >4 years), body weight (BW) (≤75 kg and >75 kg), sperm concentration (CON) (≤300 million and >300 million), total testicular volume (TTV) (≤600 cm3 and >600 cm3) and total ejaculation time (TET) (≤800 s and >800 s) of the animals from which semen was collected successfully. Heavier males (p < 0.05) that have more consistent testicles (p < 0.01) as well as quicker ejaculate responders (p < 0.001) and lower scrotal temperature had better semen (Δ motility) freezability. The lower eye temperature prior to the ejaculation (p < 0.01), lower scrotal temperature following ejaculation (p < 0.01), and conversely, higher penile temperature during the ejaculation (p < 0.001) had a higher sperm concentration. Furthermore, the sperm freezability was negatively correlated with total ejaculation time (r = −0.39, p < 0.05) and sperm abnormalities were lower in the ejaculate of dogs having a higher temperature of the scrotum, bulbus and penis. In conclusion, infrared monitoring throughout semen collection in dogs can provide information on behavioral reactions during human manipulation, as well as semen quality and testicular functionality.
