Climate change induced by global warming is expected to increase heat stress in livestock during summer months, negatively impacting the economic viability of livestock farming. This study used weather data collected from 160 districts during the summers of 2016 to 2022 to create distribution maps over time and analyze changes. Excluding mountainous regions like the Taebaek Mountains and parts of Jirisan, the temperature-humidity index (THI) was found to be above 70–80, indicating high heat stress levels. Livestock experiences adverse effects like decreased feed intake and weight loss, with the proportion of days exceeding critical heat stress thresholds for cattle (79), and pigs and poultry (74), being 60% and over 80%, respectively. Mitigation strategies such as improving livestock breeds, dietary adjustments, environmental management, and facility upgrades are necessary. Additionally, forecasting THI changes and preparing accordingly are essential for adapting to climate change impacts on livestock. KCI Citation Count: 0
