Translations:Effects of climate change on livestock/7/en

In Jamaica, considered representative of the Caribbean region, all livestock animals besides layer hens are already exposed to "very severe" heat stress in the present climate, with pigs being exposed to it at least once per day during the 5 summer and early autumn months, while ruminants and broilers only avoid daily exposure to very severe heat stress during the winter. it has been projected that even at 1.5 °C (2.7 °F) of global warming, "very severe" heat stress would become a daily event for ruminants and broilers. By 2 °C (3.6 °F), it would be felt for a longer duration, and extensive cooling systems would likely become a necessity for livestock production in the Caribbean. At 2.5 °C (4.5 °F), only layer hens would avoid daily exposure to "very severe" heat stress during the winter months.
