Antidiuretic hormone release in the bovine: values at rest, and evidence for sex differences under stressful conditions including severe hemorrhage.

OBJECTIVES: This study investigates antidiuretic hormone (ADH) plasma concentration in bulls and heifers at rest, after transportation stress, trauma and massive hyper-acute hemorrhage at slaughter, with special attention to differences between sexes. We also quantified ADH concentration in the ADH-producing hypothalamic area.
