Abstract :Gases such as carbon dioxide released into the atmosphere cause an increase in the average temperatures of ground crust and seas, called global warming. When the effects of global warming on animals are examined, they emerge as the direct effects of physical biological, chemical environment or climate. Due to extreme climatic conditions, decreases can be observed in reproduction, milk and meat yield. Extreme heat conditions have an effect on milk quality and quantity of milkers and cause shortening of lactation period. In addition, decreasing fertility, prolongation of the first insemination time due to the inability to detect the estrus, decrease in the blood flow to the uterus due to the increased body temperature resulting from high atmospheric temperature; all these lead to decreasing rate of fertilization, reduction of embryonic development and early embryonic deaths. In addition, growth and development of pups are negatively affected by these conditions. In feed animals, decrease in feed intake, decrease in feed conversion ratio and prolongation of feeding period have been observed. Factors such as climate change in bee breeding cause low productivity per colony and increase in honey bee diseases and pests. In bee breeding, other problems encountered are increasing stress induced by high temperature and decreasing productivity in egg production.
