Cows get milk fever around the time of calving due to a massive demand for calcium and an inability to meet it.

Milk fever cows usually look like this: Walk drunk Down with a S bend neck Down on their sides bloated These signs are related to the severity of the condition.
All down cows need examined for: Has she calved ( calcium is needed for uterus contractions)? Has she got black mastitis/ toxaemia ( cold udder )?

ONLY treat I/V with 4 in 1 or straight calcium.
NEVER I/V WITH MAGNESIUM YOU'LL KILL THE COW!!
Find the neck vein by blocking off low on the neck like this. You'll see the vein empty and fill up again if you release and apply your fingers.
Apply the needle on an angle like this.
Ensure there is no air in the line and bag the cow.

Use oral calcium as well to provide long acting calcium to prevent relapses.
I recommend Meloxicam ( 12 ml under the skin once ) to make the cow feel better and return to feeding ASAP. Milk with hold 6 day, meat 8 days.
If a cow can partially get up after treatment they may require phosphorus. Treat with Coforta 30ml.
