“…Further during periods of extreme heat stress, water scarcity and reduced pasture availability, indigenous breeds maintain their reproductive potential due to their smaller body size whereas the larger exotic animals may face reproductive impairments which could be attributed to their higher energy requirements. In a heat stress experiment conducted using three indigenous goat breeds from different agro-ecological zones, the Salem Black breed was identified as the superior adaptive breed when compared with the Osmanabadi and the Malabari breeds when all were assessed at the same location (Pragna et al, 2018). The authors attributed this to the test locations being less stressful than the Salem Blacks' original location.…”

“…Metabolic adaptation is considered to be one of the important means through which animals tackle heat stress challenges, essentially by reducing the metabolic heat production (Pragna et al, 2018). Thyroid hormones play an important role in regulating the thermogenesis and are also identified as an indicator for assessing the thermo-tolerance of the farm animals (Todini, 2007).…”

“…Thyroid hormones, namely triiodothyronine (T 3 ) and thyroxine (T 4 ), play a vital role in metabolic adaptation and growth performance of animals (Aleena et al, 2016). During heat stress, serum and plasma concentrations of T 3 and T 4 reduce and are likely to be due to the direct effect of heat stress on the hypothalamo pituitary and thyroid axis to decrease the production of thyrotropinreleasing hormone, which will limit basal metabolism (Pragna et al, 2018). In a recent study conducted using three indigenous goat breeds during summer, it was concluded that T 3 could serve as an indicator of metabolic activity in animals (Pragna et al, 2018).…”

Reduced concentrations of circulating T 3 and T 4 , indicative of an attempt to reduce metabolic rate and thus metabolic heat production in heifers (Pereira et al, 2008), sheep (Indu et al, 2015) and goat (Todini, 2007), have been reported.…”

“…Although animals can adapt to climatic stressors, the response mechanisms that ensure survival are also detrimental to performance (Pragna et al, 2018). The vulnerability of livestock to heat stress varies according to species, genetic potential, life stage, management or production system and nutritional status (Das et al, 2016).…”

Livestock plays an important role in the global economy. Climate change effects are not only limited to crop production, but also affect livestock production, for example reduced milk yields and milk quality, reduced meat production and reduced fertility. Therefore, livestock-based food security is threatened in many parts of the world. Furthermore, multiple stressors are a common phenomenon in many environments, and are likely to increase due to climate change. Among these stresses, heat stress appears to be the major factor which negatively influences livestock production. Hence, it is critical to identify agro-ecological zone-specific climate resilient thermo-tolerant animals to sustain livestock production. Livestock responds to the changing environments by altering their phenotypic and physiological characters. Therefore, survivability of the animal often depends on its ability to cope with or adapt to the existing conditions. So to sustain livestock production in an environment challenged by climate change, the animals must be genetically suitable and have the ability to survive in diversified environments. Biological markers or biomarkers indicate the biological states or alterations in expression pattern of genes or state of protein that serve as a reference point in breeding for the genetic improvement of livestock. Conventionally, identification of animals with superior genetic traits that were economically beneficial was the fundamental reason for identifying biomarkers in animals. Furthermore, compared with the behavioural, morphological or physiological responses in animals, the genetic markers are important because of the possibility of finding a solution to animal adaptability to climate change.
