Physiological Response to Heat Exposure

Physiological Responses of Cattle to Heat Stress

Pakistan lies in the Warm Climate Zones of the world and is subjected to extended periods of high ambient temperature and relative humidity. 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. Heat stress invokes a de...

Aging and assessment of physiological strain during exercise-heat stress.

The purpose of this study was to evaluate the physiological strain index (PSI) for different age groups during exercise-heat stress (EHS). PSI was applied to three different databases. First, from young and middle-age men (21 +/- 2 and 46 +/- 5 yr, respectively) matched (n = 9 each, P > 0.05) for maximal aerobic power. Subjects were heat acclimated by daily treadmill walking for two 50-min bout...

Effect of Zinc Sulfate and Organic Chromium Supplementation on the Performance, Meat Quality and Immune Response of Japanese Quails under Heat Stress Conditions

This study was conducted to investigate the effects of different levels of zinc sulfate and chromium picolinate on the performance, immune response and meat quality 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 factorial arrangement of treatments [zinc (0, 40, 80 mg...

Physiological responses of sunflower to water stress under different levels of zinc fertilizer

To investigate the physiological responses of sunflower (Helianthus annuus L., Alstar hybrid) to water stress under different levels of zinc fertilizer, an experiment was conducted at the Isfahan Agricultural Research Center, Isfahan, Iran, during 2008 and 2009 using a randomized complete block design within a split plot layout with three replications. Five irrigation treatments used in thi...
