Physiological and Glucocorticoid Response to Treadmill Exercise of Holstein Heifers

Ovulatory response of different GnRH analogues and subsequent corpus luteum lifespan in the presence of norgestomet in Holstein heifers

This study investigated the effect of GnRH analogues on inducing ovulation of dominant follicle (DF)and subsequent corpus luteum (CL) lifespan in the presence of norgestomet implant in Holstein heifers. Onday 6 to 8 of the estrous cycle (day 0 of the experiment), all heifers (n=15) received norgestomet implantfollowed by prostaglandin injection on days 0 and 1. On day 4, group 1 (n=4) and 2 (n=...

Physiological performance and grazing behavior of Senepol, Brahman and Holstein heifers in Puerto Rico

The response of healthy men to treadmill exercise.

Heart rates, blood pressures, and functional responses to submaximal, maximal and postexertional treadmill testing are presented for a group of 704 healthy, asymptomatic aircrewmen referred to the USAF School of Aerospace Medicine. The indicated measurements are individually described by the use of percentiles. These data provide the practicing clinician with an accurate and complete descriptio...

The Response of Healthy Men to Treadmill Exercise ROGER

THE INTERPRETATION OF ELECTROCARDIOGRAPHIC CHANGES in response to exercise testing is of established value in the early detection, diagnosis, and subsequent management of coronary atherosclerotic heart disease (CAD).'` The major emphasis placed on interpretation of the exercise electrocardiogram (ECG) has, however, tended to de-emphasize the value and significance of other commonly acquired exe...

Physiological 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 ...
