“…Again, captive environments in elephant camps (i.e., providing adequate housing and abundant diets) could mitigate oxidative stress impacts, as has been observed in a comparison between free-ranging and captive equids [12]. There was a positive association between catalase activity and the stress marker, fGCMs, which agrees with studies that showed increased catalase responses during physiological stress events [94,148], but it is not always consistent [149,150]. Few studies have been conducted on the association between blood parameters and oxidative stress markers.…”

Oxidative stress is a pathological condition that can have adverse effects on animal health, although little research has been conducted on wildlife species. In this study, blood was collected from captive Asian elephants for the assessment of five serum oxidative status markers (reactive oxygen species (ROS) concentrations; malondialdehyde, MDA; albumin; glutathione peroxidase, GPx; and catalase) in healthy (n = 137) and sick (n = 20) animals. Health problems consisted of weakness, puncture wounds, gastrointestinal distress, eye and musculoskeletal problems, and elephant endotheliotropic herpesvirus hemorrhagic disease (EEHV-HD). Fecal samples were also collected to assess glucocorticoid metabolites (fGCMs) as a measure of stress. All data were analyzed in relation to age, sex, sampling season, and their interactions using generalized linear models, and a correlation matrix was constructed. ROS and serum albumin concentrations exhibited the highest concentrations in aged elephants (>45 years). No sex differences were found for any biomarker. Interactions were observed for age groups and seasons for ROS and catalase, while GPx displayed a significant interaction between sex and season. In pairwise comparisons, significant increases in ROS and catalase were observed in summer, with higher ROS concentrations observed only in the adult female group. Lower catalase activity was exhibited in juvenile males, subadult males, adult females, and aged females compared to subadult and adult elephants (males and females) in winter and the rainy season. There was a positive association between catalase activity and fGCMs (r = 0.23, p < 0.05), and a number of red blood cell parameters were positively associated with several of these biomarkers, suggesting high oxidative and antioxidative activity covary in red cells (p < 0.05). According to health status, elephants with EEHV-HD showed the most significant changes in oxidative stress markers, with MDA, GPx, and catalase being higher and albumin being lower than in healthy elephants. This study provides an analysis of understudied health biomarkers in Asian elephants, which can be used as additional tools for assessing the health condition of this species and suggests age and season may be important factors in data interpretation.

“…In the case of camels and other animals, cortisol has been used as an indicator of stress ( El-Khasmi et al ., 2015 ; Tajik et al ., 2016 ). This may explain the increase in serum cortisol levels observed in this study.…”

Background: Biostimulation is a management practice that improves the reproductive parameters, potentiates the desire, and improves the reproductive efficiency during the short breeding season in camels. Aim: This study aims to investigate the concurrent changes in hormonal profiles in response to management and behavioral situations on camel farms in the Eastern region of Saudi Arabia. Methods: A total of 10 male and 50 female camels were used in this study. The hormonal profile of male camels was evaluated weekly starting from December to August. Results: The results show that both serum testosterone and cortisol levels increased (P < 0.01) from December to March compared to April to August. A strong negative correlation was observed between testosterone levels and temperature (r = -0.81, P<0.05), and a similarly robust negative correlation was found between cortisol levels and temperature (r = -0.83, P<0.05). The dominant rutting males showed higher levels of testosterone than the submissive males. Serum testosterone levels increased (P < 0.01) in males out of rutting after hearing the sounds of other couples before and during mating. Conclusion: Hearing sounds emitted during mating increases the testosterone output, and improves the libido of male camels during the non-rutting period. It is important to keep two individually housed males for mating purposes. One male joins the herd alone in winter (winter rutter), and the other joins in spring (spring rutter), this could keep the libido extended rutting and improve the reproductive performance in camel herds.

“…In camel, transportation stress can induce an increase of circulating levels of cortisol, lactate, glucose and MDA which is positively correlated with travel distance. 4,6 This response may be mediated by an activation of the hypothalamo-hypophyso-adrenal axis during transport stress and may reduce the preslaughter amount of glycogen then affect the postmortem biochemical evolution in muscle. The high impact of road transport distance on the intensity of OS responses has been reported by other research in domestic animals.…”

“…2 As a very stressful factor, road transport of camels to the slaughterhouse is able to induce a significant increase of circulating levels of cortisol and oxidant stress (OS) indicators 3,4 resulting in an increase of free radical generation 5 and showing a significant correlation with road transport distance. 6 Furthermore, the reaction to transport stress may have an impact on the quality of slaughtered animal meat and depends on the duration and intensity of this stressor. 7,8 The objective of the study was to investigate the effect of transport distance on the ultimate pH (pHu: 24h postmortem pH), and the levels of water, ash, glycogen, protein and OS indicators (MDA and CAT)in meat of dromedary camels.…”

Animals intended for slaughter are subjected to several stress factors which can induce harmful effects on physiological functions as well as the quality of their meat. Road transport is one of the major stressors that affect the well being of the animal. The intensity of the stress depends on several factors, namely the density of the load, the ambient temperature, relative humidity, topography and the distance of transportation. The aim of this investigation was to study the effect of transport distance on some physicochemical parameters and stress biomarkers in the meat of camel (Camelus dromedarius). Fourteen camels were selected and divided into 2 groups of 7 individuals, depending on distance traveled during transport from Settat (short distance of 72Km) or Beni-Mellal (long distance of 160km). The water content, dry matter, ash and proteins in 3 muscles (triceps, oblique and diaphragm) showed no significant variation with distance transportation. While the rate of glycogen decreases and pHu increased significantly in these muscles, when the distance of travel increases. The level of malondialdehyde increases while the catalase activity decreases significantly in all three muscles when the transport distance increases. Our findings could be explained at least partly by the effect of preslaughter stress induced by transport resulting in stress oxidant activity in camel meat rising much with road distance.
