hypocalcaemic milk fever
hypomagnesaemic grass tetany
Muscles
Milk fever: prostration of the muscular system.
Grass tetany: muscle stiffness, contractions of the tail.
Muzzle
Milk fever, mouth hardly open.
Grass tetany: mouth closed and difficult to open; grinding of teeth; in general, frothing of the mouth.
Eyes
Milk fever: sleepy eyes.
Grass tetany: wild, blood-shot eyes, frequently rolling.
Head
Milk fever: thrown to the side.
Grass tetany: thrown back.
Sensitivity
Milk fever: diminished.
Grass tetany: much greater
Pulse
Milk fever: vigorous and slightly increased.
Grass tetany: feeble and much more rapid.
Udder
Milk fever: soft.
Grass tetany: more or less normal, no excessive softness.
Temperature
Milk fever: low.
Grass tetany: normal or high.
IF a grazing animal is attacked by convulsions more than 10 days after calving the chances that it is suffering from hypomagnesaemic grass tetany are great. If, on the other hand, the convulsive manifestations appear less than 5 days after calving it is probably a case of hypocalcaemic milk fever.
