Plasma corticosterone values in genetic hypertensive and hypotensive strains of turkeys.

Plasma corticosterone levels of hypertensive and hypostensive turkeys were 2.50 and 2.19 micrograms/dl, respectively. Male turkeys of both strains had a mean plasma levels of 2.47 micrograms/dl and female turkeys had a mean level of 2.21 micrograms/gl. The average plasma corticosterone level for all turkeys was 2.35 micrograms/dl. Although the plasma corticosterone levels were higher at 1200 hr than at either 0800 or 1600 hr, the differences were not statistically significant. It was condluded that blood pressure selection had no significant effect on plasma corticosterone levels.
