this study was conducted to investigate the effects of different levels of zinc sulfate and chromium picolinate on performance, body temperature, carcass characteristics, tibia ash and serum biochemical parameters of japanese quails under heat stress condition. the birds (n = 540; 7-d-old) were randomly assigned to 9 treatment groups consisting of 3 replicates of 20 birds each in a 3 × 3 factor...

INTRODUCTION How do birds, like flamingos (Phoenicopteridae), sleep while standing on one leg? It is suggested that this behavior reduces heat energy lost through the legs [1]. Yet, the muscular energy required to actively support the body in this pose would likely offset any thermal benefits. In particular, flamingo femurs are oriented horizontally (Figure 1), which places the knee and hip joi...

Background & Aims of the Study: Heat Stress is a major factor in many industrials and heat stress is one of occupational hazards in the workplace and severely affects the health and productivity, heat stress can decrease efficiency, increase accidents and reduce safety levels. Aim of this study was comparing the heat stress indices of HSI and WBGT and core body temperature in steels ind...

This study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (BBB) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. Methods: Each age group of rats was sub di...
