Evidences from the past century have recorded that global warming has been increasing constantly and will continue to rise at the rates that are estimated to be between 0.1 to 0.2℃ per decade in the next century. We cannot negate the fact that rising temperatures would also effect harshly to animal sector particularly dairy sector. So far, it has been noticed that rising temperatures causing heat stress among dairying. However, at cellular level molecular chaperones (genes/heat shock proteins) gets activated and released. Genes that get up/down regulated following heat stress have been shown to be involved in protein folding, protein degradation, protein synthesis and detoxification, oxygen transport, phosphorylation etc. in different animals. In this study we discuss the impact of heat stress on cow’s dairy capacity, health and alongside the responses of different molecular chaperones in protecting the existing proteins for routine health and production. Additionally, the different mechanism that underlie activation of the heat shock proteins response and the role of heat shock proteins as cyto-protective molecules to develop them into active molecules as regulators of heat stress in animals.
