“…The temperatures observed in the present study were higher when compared to the data obtained by Chacur et al (2016a) in lactating cows and negative to the California Mastitis Test (CMT), pregnant and non-pregnant, with a surface temperature ranging from 30.5ºC to 36.8 ° C in the upper third, from 29.7ºC to 36.9ºC in the medium and from 27.9ºC to 35.9ºC at the end. The factor that may be related to this result is the high relative humidity of the air (94%) observed on the day of the capture of the thermographic images, which significantly contributes to the retention of heat due to the difficulty in the process of eliminating it to the environment.…”

O objetivo do estudo foi realizar a avaliação termográfica das glândulas mamárias e globo ocular de fêmeas bovinas leiteiras em uma propriedade rural no município de Mojuí dos Campos, no Oeste do Pará. Foram utilizadas oito (n=8) fêmeas leiteiras pluríparas da raça Girolando, mantidas em sistema semi-intensivo, com idade e peso médio de 7 anos e 450 kg, respectivamente. As fêmeas foram divididas em dois grupos experimentais, Lactantes (LACT, n=4) e Não-Lactantes (N-LACT, n=4). Foi utilizada uma câmera termográfica infravermelho para a obtenção da temperatura superficial das glândulas mamárias (região do terço superior, médio e final) e do globo ocular (região medial). Utilizou-se o programa Past versão 2.16, obtendo-se média e desvio padrão e análise de variância com o teste de Anova One-Waye Tukey (5%). Ao comparar os grupos LACT e N-LACT não foi detectada diferença significativa entre os mesmos (P≥0,05). Foram observadas nas glândulas mamárias temperatura média superficial no grupo LACT e N-LACT de 40,2ºC±0,8 e 39,6ºC±0,9, 38,9ºC±0,6 e 38,0ºC±0,7, e 37,5ºC±0,6 e 36,8ºC±0,7 na região do terço superior, médio e final, respectivamente. As fêmeas do grupo LACT apresentaram temperatura média do globo ocular de 37,3ºC±0,8 e as N-LACT de 36,3ºC±0,8. Foi constatada maior amplitude térmica no terço médio das glândulas mamárias e maior temperatura na região do globo ocular das fêmeas lactantes. Assim, a termografia infravermelho foi capaz de determinar que as fêmeas avaliadas estavam em condições adequadas de conforto térmico ambiental e as modificações fisiológicas decorrentes da lactação não foram capazes de ocasionar elevação da temperatura superficial.

“…Climatic variations can affect maintenance of the body surface temperature as well as the RT in Nellore bulls (Ruediger et al, 2016), dairy cows (Chacur et al, 2016a), goats (Ricarte et al, 2014) and buffalo (Sevegnani et al, 2016). In this study, when correlating the weather variables (WBGT, TA, TG and UR) with different body region surface temperatures and with the RT, the data were strongly correlated between weather factors and body and rectal temperatures in the afternoon, when the temperature was warmer, and there was a moderate correlation in the morning, when there were milder temperatures (Nabenishi et al, 2011;Talukder et al, 2014).…”

“…Different invasive techniques have been used to measure changes in body temperature during estrus, but these may be influenced by the stress caused to the animal (Clapper et al, 1990;Mosher et al, 1990;Kyle et al, 1998;Redden et al, 1993;Fisher et al, 2008). Infrared digital thermography (IDT) is a non-invasive technology that allows accurate measurement of surface temperature (Chacur et al, 2016a) and has great potential in its applicability in animal reproduction. Few studies, however, have been conducted in this area of research (Ricarte et al, 2014).…”

The objective of this study was to evaluate variations in the orbital area, muzzle and vulva surface temperatures and progesterone (P4) concentrations during follicular and luteal phases in Murrah buffalo and whether these temperatures are influenced by the weather patterns. Forty cows were submitted to P4-based hormonal protocol. After P4 device withdrawal transrectal ultrasonography and infrared digital thermography were performed daily until day 16 and on days 20, 24, 28 and 32 to follow the ovulation as well as the vulva, orbital area and muzzle temperatures. In addition, the weather variables were evaluated, as well as rectal temperature (RT) and P4 and cortisol concentration. Vulva, muzzle and orbital area temperatures correlated positively with RT and with weather data. Greater temperatures of the vulva, orbital area and muzzle were detected during the period of estrus. The vulvar surface temperature (VST) was not influenced to a great extent by weather factors during the morning, so this period was chosen to evaluate the influence of the phase of the estrous cycle on VST. The VST was less during days 16, 20, 24 and 28 (diestrus) and P4 concentration was inversely proportional to the VST. Muzzle, orbital area and RT, however, were not of the same pattern. Negative correlations were observed between VST and P4 concentrations. It is concluded that VST undergoes changes during the reproductive phases, correlating with P4 concentration. The weather factors influence the temperatures of the body surface areas, and the morning is the most desirable time to perform the thermographies.

“…However, the use of the non-invasive technology called infrared thermography (IRT) is increasing because this technique has the capacity to take precise measurements of the surface temperatures of certain corporal regions from a distance of 30 cm or more. IRT thus facilitates J Anim Behav Biometeorol (2020) 8:288-297 the identification of thermal alterations characterized by an increase or decrease of skin surface temperatures (Chacur et al 2016;Sevegnani et al 2016;Menegassi et al 2018;Casas-Alvarado et al 2020;Bertoni et al 2020;Mota-Rojas et al 2020a;Guerrero-Legarreta et al 2020).…”

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.
