Temperature stress is a phenomenon that negatively affects animal welfare, decreases the efficiency in animal production, increases health problems and leads to economic losses. The correct definition of animals with temperature stress enables the development of innovative approaches to minimize the low temperature-related productivity observed in the summer, to understand the biological mechanisms of this stress reducing milk productivity, growth and reproductive performance. The biological mechanism of temperature stress is due to a partial decrease in food consumption in ruminants. There are also changes in the endocrine system due to high environmental temperature, the decline in relaxation and nutrient absorption, the increase in life-performance requirements resulting in differences in the use of nutrients and energy necessary for productivity. In temperature stress, a thermal distinction in the use of nutrients in the body has been observed. All of this is a mechanism used by heat exposed animals to reduce the heat production in their bodies. This article discusses how animals react to temperature stress and the effects of temperature stress on nutrient metabolism.
