Climate impacts are related to changes in precipitation, temperature, atmospheric greenhouse gas concentrations and temperature levels that affect each biological system. These factors contribute to changes in biodiversity, oceans warming, natural reproductive cycles, feeding behavior, heat stress, animal agitation, water-related stress and other consequences such as increased parasitic infections, reduced reproductive performance, declining trends in food and forage resources for animals and other species. In recent years, the number of publications on the effect of temperature on goats have increased. Especially, publications investigating the expression levels of heat shock protein genes are quite popular for measuring of heat stress in different goat breeds. Heat shock factor 1 (HSF1), heat shock protein 60 (HSP60), HSP70, HSP90 and ubiquitin have been associated with the capacity of small ruminants to withstand heat stress challenges. Among these heat tolerance genes, HSP70 has been identified as the ideal genetic marker for heat tolerance in small ruminants. Identification of cellular and molecular markers and use of marker-assisted breeding programs may pave the way for the development of goat breeds that are resistant to changing temperature conditions due to global warming.
