“…Nevertheless, Aleena et al [33] documented lower HSP 70 mRNA expression in adapted Salem Black goats as compared to Malabari and Osmanabadi breeds. Similarly, Kumar et al [86] observed lower expression of HSP 70, HSP 60 and HSP 90 in heat adapted Barbari goats than in less adapted Sirohi and Jhakarana breeds. Relatively higher HSP gene expression level in susceptible breeds probably indicates a greater requirement to protect cells from heat stress damage.…”

“…Animals with light/white colored coats have an advantage in tropical regions, because the coat reflects 50-60% of direct solar radiation, in contrast to dark-colored animals [71]. Barbari goat breeds have a white coat color and small body size and show better thermotolerance than other goat breeds such as the Sirohi and Jhakrana reared and developed under similar regions [86]. Fadare et al [87] demonstrated the lower thermotolerance of darkly pigmented sheep breeds.…”

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.

“…In a recent study by Pragna et al (2017) identified Salem Black goat breed to be better breed to adapt to heat stress as compared to both Malabari and Osmanabadi goats. Further, increased RR in both Sirohi and Jhakrana breeds of goat as compared to Barbari goat bread and higher RT reported in Barbari goat breed compared to both Sirohi and Jhakrana breeds of goat during heat stress clearly established the breed differences in adaptation within a species (Kumar et al 2017). Similarly, in a comparative study by Ashutosh et al (2000) identified that the RR and RT are higher in Avivastra sheep than Chokla sheep breed during heat stress exposure.…”

Climate change associated heat stress was established to be the crucial factor, which negatively influences animal production. The animals possess several adaptive mechanisms which are helpful for their survival in harsh environmental conditions, but while doing so their productive performances are compromised. Among the various mechanisms, which helps to maintain homeostasis in animals, Physiological adaptability was considered one of the primary response mechanisms by which the heat stressed animals survive the heat stress. This review is therefore an attempt to provide the audience an updated review on the subject to signify the importance of physiological responses in animals and their role in surviving the stressful environment. Respiration rate (RR), pulse rate (PR), rectal temperature (RT), sweating rate (SR) and skin temperature (ST) are the cardinal physiological variables which helps to maintain the heat balance and homeostasis in the stressed animals. Among the various physiological variables, RR, RT and ST were established to be ideal indicators for quantifying heat stress in several farm animals. Therefore, these variables can be effectively used to assess the severity of heat stress in livestock. Although these variables are considered significant in establishing the heat stress impact in animals, a wide genetic variation was also established in these response mechanisms. Further, variations in physiological adaptability were also established between indigenous, cross bred and pure bred animals. The indigenous livestock breeds were tipped to be exhibiting less physiological variability as compared to their counterparts. These discussions vividly indicate the importance of studying in detail the physiological adaptive mechanisms in different farm animals and these efforts can help the farming community to identify the suitable agroclimatic zone specific livestock breeds which can go in long way to help to ensure climate resilient livestock production.

“…This impact climatic change may impact on performance of goats due to the assumption that seasonal variation led to different in the level of concentration of HSP to different extent in breeds adapted to temperature climatic conditions. 6 As added, Yilmaz et al 17 reported that mRNA gene expression levels for hsp60 in Saanen goats was 1.72 in the winter, whereas, mRNA expression level measured more than mRNA gene expression level measured during the spring, 18 stated that hsp60 gene expression was significantly higher (p<0.01) for Sirohi (7.8) and Jhakrana (5.3) as compared with Barbari (2.1) goats.…”

From 160 goats as seen above it was conducted to study the impact change climate on physiological performance of goats. A total of 24 femal goats were involved in this phase: Alpine (n=8), Saanen (n=8) and Boer (n=8). All animals subjected to one week for adaptation before starting collection of physiological parameters and climate data. Physiological parameters including pulse rate (PR), respiration rate (RR), body temperature (BT), skin temperature (ST) and head
