Selection of appropriate biomatrices for studies of chronic stress in animals: a review

“…In commercial animal farming, environmental factors such as radiation, air movement, precipitation, air temperature, and relative humidity should all be considered to minimize the risk of heat stress [60][61][62]. Heat stress occurs when an animal's heat load is higher than its ability to dissipate heat, damaging its general health; immunity, productivity, and welfare can be severely affected [62][63][64]. Heat stress triggers the release of stress hormones such as cortisol and epinephrine, which cause the body core temperature to rise further, weakening the immune system.…”

Negative association between high temperature-humidity index and milk performance and quality in Korean dairy system: big data analysis

“…Similar to global climate change, an increase in air temperature has been observed in South Korea. It has been reported that the increase in annual average temperature has been 0.5 °C since decade (2010-2019) [5]; therefore, the decrease in dairy productivity is an emerging issue in South Korea. The temperature-humidity index (THI) is a value estimated using temperature (dry or wet) and humidity (direct or relative) to measure the degree of HS.…”
