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.
