Effects of hypocalcaemia on abomasal motility

Abomasal mechanical and myoelectric activity were measured in two adult Holstein cows. Hypocalcaemia was induced using a constant infusion of disodium EDTA and serum total and diffusible calcium concentrations were measured.

Description
Summary:Abomasal mechanical and myoelectric activity were measured in two adult Holstein cows. Hypocalcaemia was induced using a constant infusion of disodium EDTA and serum total and diffusible calcium concentrations were measured. Abomasal motility remained normal in the face of declining calcium concentrations until a threshold value was reached (1.2 +/- 0.2 mmol litre-1) below which all mechanical and electrical activity was absent. A similar threshold effect was observed when calcium concentrations were allowed to rise. These data do not support hypocalcaemia as being a clinically important cause of abomasal atony.
