Decreasing cultivated and farge areas and changing climatic zones hence on climate change cause a trouble besides affect countries agricultural and livestock breeding activities negatively. Livestock breeding has an importance to meet the nutritional and economical requirement notably milk and meet in changing climate conditions. Because theese animals can convert low quality roughage to high quality animal protein and can adapt to a wide climate range. The effects of heat stres on yields are observed on wild animals along livestock animals, especially ruminants. Although there are several researches about phsiologycal responds against heat stress, knowladges on cellular and genetic levels are not enough yet. Heat Shock Protein ( HSP) genes are one of the most important cellular respond members. In this study we aimed to mention reports about general heat stres properties on farm animals, heat stres response , adaptaion and one of the important cellular respond members HSPs (Heat Shock Proteins).
