Cortisol responses to physical and pharmacological stimuli in heifers.
The aim of this study was to assess bovine plasma cortisol response to blood sampling, to 5-min isolation in a novel arena and to dexamethasone blockade and ACTH stimulation. Twelve 10-month old heifers of the Friesian and Salers breeds were used. Blood collection, carried out via a jugular cannula or caudal venipuncture, had no significant effect on cortisol level. This level increased by abou...
متن کاملThe responses of horses to predator stimuli
It is not known whether the instincts of wild horses have remained strong during their centuries of domestication. Knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. In this current research, we studied the behavior of fifteen Caspian miniature horses of different ages and sexes using sti...
متن کاملPhysiological Responses to Des in Heifers
The purpose of this study was to determine the influence of diethylstilbestrol (DES) and differing nutritional regimens on respiratory and heart rates, electrocardiogram (EKG) patterns, rectal temperature and blood lactic acid values of steers. Sixteen Angus steers were fed a 75% concentrate diet ad ffbitum for a 28-day standardization period. Eight steers were then fed 20 mg DES per steer per ...

متن کاملCortisol, sexual arousal, and affect in response to sexual stimuli.
INTRODUCTION Theoretically, the physiological response to stress should inhibit the sexual response. This has been demonstrated experimentally in animal models, and correlationally in studies of human reproduction. It is reasonable to expect, then, that the stress response would be blunted during sexual arousal, and several researchers have found a pattern of decreasing cortisol during sexual a...
