Changes

Increasing the salt intake of an animal increases blood pressure in the short term.  It increases the osmolarity of the blood which therefore increases water movement from tissues to the blood causing an increased circulating volume.  As a result of this increased osmolarity more ADH is released as the osmoreceptors in the hypothalamus are triggered.  This results in increased water retention in the kidneys further increasing the circulating volume.  Secondary to the increase in salt the thirst centre is stimulated to increase fluid intake to try and counter act the increased osmolarity.  This would increase blood volume and therefore pressure temporarily until this was corrected by the compensatory mechanisms detailed above.
