Heat stress and thermoregulatory responses of goats: a review

The purpose of the present review is to provide an integrative explanation of thermoregulatory responses of goats at behavioral, physiological, biochemical, productive and reproductive level during heat stress and also the strategies for its alleviation.

Metabolic and hormonal acclimation to heat stress in domesticated ruminants.

A better understanding of the adaptations enlisted by ruminants during heat stress is necessary to enhance the likelihood of developing strategies to simultaneously improve heat tolerance and increase productivity.

EFFECTS OF HEAT STRESS ON PHYSIOLOGICAL TRAITS IN SHEEP

During the early stage of embryonic life, the total cell number and placentome size were greatly reduced and the cell size only slightly decreased by exposure to warm temperatures, compared to thermo-neutral temperatures.

In tropical and subtropical regions, high environmental temperature, relative humidity, solar radiation and thermal stress are the most crucial constraints on animal welfare, health, survival

Physiological Responses of Cattle to Heat Stress

The objective of this article is to review the physiologic/adaptive responses of acclimated cattle to heat stress emphasizing its affects on nutrient acquisition and metabolism, acid-base chemistry and hormonal balance of the body.

Invited review: Effects of heat stress on dairy cattle welfare.

The objectives of this review were to present an overview of the effects of heat stress on dairy cattle welfare and highlight important research gaps in the literature and to identify improved comprehensive cow-side measurements that can indicate real-time responses to elevated ambient temperatures.

Heat Stress Effects on Water Metabolism of Goats in Harsh Environments

A definition of heat stress and its effects on water metabolism on goats will be the scope of this chapter.

Prolonged and continuous heat stress in cattle: Physiology, welfare, and electrolyte and nutritional interventions.

Monitoring the physiological responses of Bos taurus and Bos indicus to conditions similar to those experienced by cattle being shipped from southern Australian to the Middle East indicated improved buffering capacity and a weight advantage for supplemented cattle, even in the absence of extreme heat stress.
