“…The surface temperature of the cranial and caudal cisterns was higher in the groups of calves and heifers (Chacur et al 2018), a finding that coincides with reports in the literature which mention that adult females have a higher proportion of adipose tissue in the mammary structure (Hovey and Aimo, 2010) that could act as a form of thermal insulation and, therefore, impede heat dissipation through the skin. Observations of the group of gestating buffaloes showed a correlation between rectal temperature and the temperature of the cranial-to-caudal teats that, in turn, was linked to the temperature of the cranial and caudal cisterns.…”

“…These results provide evidence of the existence of a connection between body temperature and the surface temperature of the udder that obeys the metabolic demands of both, and that can be studied using IRT (Chacur et al 2018), though it is necessary to keep in mind that temperatures can vary depending on the exact region of the udder evaluated, as shown in Figure 3. The thermograms in Figure 4 were taken immediately after automatic mechanical milking.…”

“…Observations of the group of gestating buffaloes showed a correlation between rectal temperature and the temperature of the cranial-to-caudal teats that, in turn, was linked to the temperature of the cranial and caudal cisterns. This demonstrates the existence of a relation between temperature variations and the evolution of the physiological demands of the udder (Chacur et al 2018), given that the end of the gestation period is a stage of intense mammary development marked by greater vascularization and higher temperatures (Prosser et al 1996;Davidson and Stabenfeldt, 2014). Another important finding involved the group of lactating buffaloes (Chacur et al 2018), where results show lower temperatures in the rectum and on the surface of the cranial cistern, likely related to the reduced metabolic activity and blood flow that occur during mammary involution and result in lower milk production (Capuco and Akers, 1999).…”

The objective of this review article is to discuss and analyze the most important scientific findings from studies of vascular microcirculation in the river buffalo using infrared thermography (IRT), as well as the thermal windows utilized with this species. The goals are to define the scope and areas of opportunity for IRT use in evaluating physiological processes and identifying potential applications in reproductive events associated with andrological traits in males and the detection of estrus and udder health in females. IRT has allowed the development of diverse perspectives regarding the comparative physiology of events like thermogenesis, peripheral blood flow, respiratory physiology, and mechanisms that reduce body temperature. The case of the river buffalo is no exception. According to the information analyzed, the temperatures of the orbital area, muzzle, and vulva have proven efficient for evaluating thermal comfort, a particularly important aspect of this species given its limited thermoregulating capacity and constant exposure to extreme temperatures. Evaluating scrotal temperature has been revealed as an appropriate tool for evaluating semen quality, while the surface temperature of the udder is useful in assessing mammary development in female buffaloes, two aspects of great zootechnical importance. In future studies, IRT will play a fundamental role in enhancing our understanding of the river buffalo's mechanisms of vascular microcirculation, with applications in productivity and behavior.

“…When studying the reproductive physiology of buffaloes, Chacur et al (2018), reported that inadequate management causes problems of embryo absorption and abortion in buffaloes, especially with respect to thermal stress. This problem can be early diagnosed, through a non-invasive technique such as infrared thermography.…”

Interest in buffalo breeding has increased, due to certain advantages in relation to cattle breeding. The objective of this article was to review the reproductive biological characteristics of buffaloes. Buffaloes have their peculiarities regarding the reproductive characteristics, the females are seasonal polyestrous breeders of short days, the puberty’s buffalo is reached in ages more than in the bovine, the detection of the estrus is more difficult because of the estrus it happens at dawn and the females of buffalo have few physiological changes producers have difficulty detecting estrus. The gestation period varies between 300 and 320 days. Males have smaller external reproductive organs and less intense sexual behavior in relation to cattle. Buffalo females exhibit reproductive differences such as the hyperpigmented vulva and smaller and lighter, more rigid and tortuously inner structures with more muscle tone. There are some advantages in the creation of buffaloes were evidenced, such as their rusticity and adaptation to areas that would be unsuitableto cattle production, besides counting on products such as milk and meat of good quality. Several protocols of oestrus and ovulation synchronization have been adopted, to improve reproductive efficiency. These protocols have resulted in a pregnancy rates increase of 30% to 50%. It is concluded that buffalo breeding has space within the animal production system, especially in areas that would be suitable for the breeding of other ruminant species.

“…The application of IRT in livestock production has been studied for several species such as beef cattle (Montanholi et al, 2009;LokeshBobu et al, 2018;Lowe et al, 2019;Vicentini et al, 2020), dairy cows (Chacur et al, 2016;Daltro et al, 2017;Schaefer et al, 2018;Sathiyabarathi et al, 2018;Tangorra et al, 2019;Deak et al, 2019), laying hen (Loyau et al, 2016), buffaloes (Barros et al, 2016;Sevegnani et al, 2016;Ahirwar et al, 2017;Ahirwar et al, 2018;Chacur et al, 2018), dairy sheep (Martins et al, 2013;Castro-Costa et al, 2014;Cannas et al, 2018;Byrne et al, 2019;Castells et al, 2019;Sutherland et al, 2020;Pulido-Rodríguez et al, 2021), dairy goats (Silva et al, 2014;Façanha et al, 2018), Broiler chickens (Nascimento et a., 2014;Candido et al, 2020), turkey (Moe et al, 2018) and pigs (Justino et al, 2014;Boileau et al, 2019), Table 2.…”

Infrared thermography has become increasingly promising in veterinary medicine, for being a non-invasive method for detecting body thermal variation. The objective of this review was to elucidate some applications of infrared thermography and its importance on animal livestock. This tool can substitute conventional techniques for diagnosing diseases, inflammation and fever. The body temperature is an important indicator to diagnostics and to understanding physiological aspects due to the close relation between abnormal temperatures and inflammatory processes. Also, it can help monitor reproductive performance and identify more efficient animals, among other purposes. The measurement of infrared temperature allows identifying sick animals, before the appearance of clinical symptoms, making treatment and isolation faster and more accurate, enhancing the profitability and sustainability of the system. However, this tool has some limitations, such as the animal species and environmental factors. Thus, further studies are needed for the application of the thermographic on animal livestock.
