“…A comparative study among tropical indigenous goat breeds (Osmanabadi, Malabari, and Salem black) showed differences in feed intake during the summer season, being reduced in Malabari animals but not the other breeds during heat stress [75]. Likewise, heat stress reduced feed intake in second-cross Merino (Poll Dorset × Merino/Border Leicester) lambs, but not Dorper lambs when both breeds were subjected to heat stress [92].…”

“…A comparative assessment study between Baladi and Damascus goat breeds showed a greater rate of reduction in body weight in the latter (2.85% vs. 3.33%) under thermal challenge [74]. Pragna et al [75] also reported a reduction in body weight and body condition score among indigenous goat breeds under heat challenge, with the effect being greater in the Osmanabadi breed than Malabari and Salem Black breeds. Malabari and Salem Black breeds appear to tolerate arid conditions whilst sustaining productivity.…”

“…Additionally, fat stored in the tail also acts as an energy and water source in these breeds during periods of dietary restriction. A comparative study between three Indian goat breeds showed differences in their rump height, which is higher in the Salem Black (more tolerant) breed than the Malabari and Osmanabadi breeds [75]. Chacón et al [91] suggested that this as an evolutionary adaptation which assists in avoidance of reflected heat radiation from the ground, while grazing under hot conditions.…”

“…In Osmanabadi, Salem Black and Malabari goat breeds, insulin-like growth factor 1 (IGF-1) mRNA expression were reduced under thermal stress, with the rate of reduction being lower in the Salem Black breed [75]. This could indicate better adaptability of Salem Black breed over the other two breeds in terms of sustaining productivity in hot environments.…”

Climate change is a major global threat to the sustainability of livestock systems. Climatic factors such as ambient temperature, relative humidity, direct and indirect solar radiation and wind speed influence feed and water availability, fodder quality and disease occurrence, with production being most efficient in optimal environmental conditions. Among these climatic variables, ambient temperature fluctuations have the most impact on livestock production and animal welfare. Continuous exposure of the animals to heat stress compromises growth, milk and meat production and reproduction. The capacity of an animal to mitigate effects of increased environmental temperature, without progressing into stress response, differs within and between species. Comparatively, small ruminants are better adapted to hot environments than large ruminants and have better ability to survive, produce and reproduce in harsh climatic regions. Nevertheless, the physiological and behavioral changes in response to hot environments affect small ruminant production. It has been found that tropical breeds are more adaptive to hot climates than high-producing temperate breeds. The growing body of knowledge on the negative impact of heat stress on small ruminant production and welfare will assist in the development of suitable strategies to mitigate heat stress. Selection of thermotolerant breeds, through identification of genetic traits for adaption to extreme environmental conditions (high temperature, feed scarcity, water scarcity), is a viable strategy to combat climate change and minimize the impact on small ruminant production and welfare. This review highlights such adaption within and among different breeds of small ruminants challenged by heat stress.

“…Thus, further molecular mechanisms and physiological consequences of HS using an animal model are highly recommended.Previous studies have shown HS-induced physiological and biochemical variations in many animals, such as rats [10,11], cows [12], and chickens [13]. The HS causes an imbalance of glucocorticoids, the adrenocorticotropic hormone, the growth hormone, and the norepinephrine hormone, resulting in detrimental metabolic changes [10,14,15]. Furthermore, a set of proteins involved in the antioxidant stress response and inflammatory response, including catalase, glutathione peroxidase, and C-reactive protein were affected by HS [16][17][18][19].…”

Heat stress (HS) is challenging in humans and animals as it is a complicated regulatory mechanism. This prompted us to characterize the physiological and molecular responses of a HS-animal model. In this study, a rat model system was developed by using three temperature treatments (40°C, 42°C, and 43°C) and sixteen biochemical indicators in blood at 42°C for 30 min (H30), 60 min (H60), and 120 min (H120). In addition, transcriptomic profiling was carried out in H120-rats' blood, liver, and adrenal gland samples for detection of the genes of interest. Our findings demonstrated that the adrenocorticotropic hormone, catalase, prolactin, growth hormone, and lactic acid have significant spatiotemporal variation in the H120-rats as compared with the control. Furthermore, through transcriptomic screening, we documented a high ratio of differentially expressed genes (DEGs) in adrenal glands, liver, and blood, respectively. Among them, Nup153, Plxnb2, Stx7, Hspa9, Chordc1, Pde4d, Gm2α, and Rnf125 were associated with the regulation of HS and immune response processes. Notably, 36 and 314 of DEGs in blood and adrenal glands were detected in the composition of the extracellular exosome, respectively. Furthermore, the correlation analysis between gene transcripts and biochemical indicator levels identified the Lgals3, S1006, Fn1, F2, and Kng1l1 as key candidate genes for HS encoding extracellular exosomal proteins. On the basis of our results, it was concluded that the current rat model provides a molecular basis for future research in HS resistance in humans and livestock.Genes 2020, 11, 306 2 of 23 (e.g., crossbreeding), have not achieved long-lasting, cumulative and significant effects [9]. Thus, further molecular mechanisms and physiological consequences of HS using an animal model are highly recommended.Previous studies have shown HS-induced physiological and biochemical variations in many animals, such as rats [10,11], cows [12], and chickens [13]. The HS causes an imbalance of glucocorticoids, the adrenocorticotropic hormone, the growth hormone, and the norepinephrine hormone, resulting in detrimental metabolic changes [10,14,15]. Furthermore, a set of proteins involved in the antioxidant stress response and inflammatory response, including catalase, glutathione peroxidase, and C-reactive protein were affected by HS [16][17][18][19]. Recently, microarray and next-generation sequencing studies have displayed widespread changes in gene expression in response to HS, the exploration of useful indicators to predict and prevent HS in animals has yet to be defined.In the context of the critical effects of HS on human and animal health, the current study was designed to explore the physiological, biochemical, and transcriptomic responses to HS in Sprague Dawley (SD) rats. The current research targets the key biomarkers that are sensitive to HS. In addition, the altered expression of genes related to HS response was detected by performing transcriptomic screening in blood, liver, and adrenal gland tissues post HS. Collectively...

ObjectivesIn this study, the effects of sex and birth type on growth performance, withers height (WH), radiographic measurements and selected hormone profiles in Gurcu goat kids were investigated.MethodsTwenty kids (single female = 5, single male = 5, twin female = 5, twin male = 5) were included in the study. Body weight (BW), WH, radiographic measurements (humerus length [HL], radius length [RL], proximal humerus epiphyseal plate width [HEP] and distal ulna epiphyseal plate width [UEP]) and biochemical analysis (for serum calcitonin, free triiodothyronine [FT3], free thyroxine [FT4], growth hormone [GH] and insulin‐like growth factor‐I [IGF‐I]) were performed at 1, 3, 5, 7, 9 and 12 months of age.ResultsBW was significantly higher in males starting from the seventh month compared to females (p < 0.05). HL was higher in males at seventh (p = 0.009) and ninth (p = 0.033) months, whereas RL was lower in twins at the third month (p = 0.021). UEP was wider in males at seventh (p = 0.008) and ninth (p = 0.036) months. Closure of HEP was observed in 65% of kids by the 12th month. Calcitonin was lower in twins at third (p = 0.045) and fifth (p = 0.006) months, with changes observed due to group and time effects (p < 0.05), whereas other hormones only changed with time (p < 0.05). Positive correlations were observed between BW, WH, HL, RL and IGF‐I. There was a negative correlation between BW, WH, HL, RL, IGF‐I and HEP, UEP, calcitonin, FT3, FT4, GH.ConclusionSex and birth type in Gurcu goat kids may have an impact on growth performance, radiographic measurements and certain hormonal profiles.
