Dairy cows possess some physiological characteristics such as underdeveloped sweat glands, limited heat dissipation area per unit weight, and propensity to generate substantial heat during milk production. Consequently, this makes them susceptible to heat stress, which in turn brings many adverse effects to dairy cows and is one of the main constraints on the sustainable development of the dairy industry. Normal immune function, digestive tract homeostasis and mammary gland health are the fundamental guarantees for dairy cows to realize their production potential. Heat stress can seriously impair immune function, disrupt the digestive tract homeostasis, and damage the mammary health of dairy cows. This article systematically reviewed the effects of heat stress on immune function, digestive system homeostasis, mammary function and health of dairy cows, as well as the research progress on the involved mechanisms. It aims to provide theoretical reference for mitigating the damage caused by heat stress to dairy cow health and formulating healthy feeding and management plans.
Key words: heat stress; dairy cows; immune function; digestive function; mammary gland health
