Simple Summary Heat stress in dairy cows can be assessed based on induced responses
from behavioral, physiological, and health aspects. We can use reaction norm models to …

Introduction Increasing global temperatures present a significant challenge to livestock
production. The dry period is an important stage in the production cycle of cow, and …

Heat stress (HS) adversely influences dairy cattle welfare and productivity. This study aimed
to investigate the effects of HS on production and physiological parameters of Holstein cows …

Heat stress (HS) adversely influences productivity and welfare of dairy cattle. We
hypothesized that the thermoregulatory mechanisms vary depending on the exposure time …

This study examined the effects of 7 days of heat stress on eight early lactating Holstein
cows in climate-controlled chambers. The early lactating Holstein cows (42±2 days in milk …

Background Rises in global warming and extreme weather occurrence make the risk of heat
stress (HS) induced by high ambient temperatures more likely in high-yielding dairy cows …

Simple Summary When the ambient temperature exceeds the upper limit of a certain
temperature range, heat stress is triggered and then negatively affects the production …

The main objective of this study was to determine the potential impact of heat stress (HS) on
milk production and lactation curve parameters of Holstein dairy cows. Milk, fat, protein, and …

Lactating dairy cows exhibit a myriad of responses to heat stress. These responses partially
facilitate the thermal balance between heat gain and heat loss, but also account for …

This study evaluates the response of dairy cows to short and extended heat stressing
conditions (from 1 to 28 days), as expressed in changes in their behavior. Due to climate …
