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...

متن کاملNon-invasive cortisol measurements as indicators of physiological stress responses in guinea pigs
Non-invasive measurements of glucocorticoid (GC) concentrations, including cortisol and corticosterone, serve as reliable indicators of adrenocortical activities and physiological stress loads in a variety of species. As an alternative to invasive analyses based on plasma, GC concentrations in saliva still represent single-point-of-time measurements, suitable for studying short-term or acute st...

Non-invasive techniques for analysing hormonal indicators of stress.
The growing concern over animal welfare has led to an increased awareness of the need to monitor and reduce stress in laboratory, zoo, and farm animals. To do so, valid and reliable methods are necessary. In the present work, we discuss non-invasive techniques for analysing hormonal indicators of stress, particularly glucocorticoids. Specifically, we describe methods for analysing samples of sa...
