Invited review: Lethal heat stress: The putative pathophysiology of a deadly disorder in dairy cattle [PDF]

open access: yesJournal of Dairy Science, 2022
Heat stress (HS) reduces production and efficiency in almost every metric of the dairy operation, and it thus compromises profitability and sustainability. If the magnitude of HS progresses, it can become lethal. Death can occur acutely or days following the heat load, even if environmental conditions have become nonstressful. Consequently, lethal heat

Pathophysiological Changes in Female Rats with Estrous Cycle Disorder Induced by Long‐Term Heat Stress [PDF]

open access: yesBioMed Research International, 2020
High‐temperature exposure is detrimental to women’s reproductive health; however, the impact caused by long‐term high temperature is not comprehensive, and a stable model of estrous cycle disorder induced by a high temperature is yet lacking. Herein, we aimed to establish a stable and effective model of estrous cycle disorder in female rats induced by ...

The Relationship between the Heat Disorder Incidence Rate and Heat Stress Indices at Yamanashi Prefecture in Japan [PDF]

open access: yesAdvances in Meteorology, 2016
In recent years, the risk of heat disorder in daily life has increased dramatically because the thermal environment has been deteriorating. The main objective of this study was to examine regional differences in the relationship between heat disorder incidence rate and heat stress indices at Yamanashi Prefecture, Japan.

Heat Stress and feeding strategies in meat-type chickens [PDF]

open access: yes, 2011
Heat stress can induce hyperthermia in poultry. A reduction in heat load can be achieved by increasing the possibilities for dissipation, decreasing the level of heat production or by changing the thermal production pattern within a day.
