Cows can come down with milk fever at any stage in their lactation. Adeleine went down with milk fever at 8 months into a lactation. Dad didn't recognize it at first and so we called the vet (a rare thing here). Dad had figured it out before the vet arrived but the vet treated her. Big mistake. he was wanting to put two bottles of calcium IV into a cow that was still standing! Dad wouldn't let him. He put the second bottle sub-Q. The cow went down less than 12 hours later (duh...calcium overload). Dad treated her sub-Q with one bottle and she was fine.
At the school it wasn't uncommon for cows to go down a week after calving. Patricia was wobbly heading out of the barn after milking a week post calving. I mentioned to the assistant farmer that she looked like she was going to go down, but she wasn't put in the box stall. It was a week post calving.."cows don't go down that long after." Sure enough she was down flat out in the field the next morning.
A lot has to do with feeding and the individual cows. We rarely have cows go down after the first 48. But it has happened in the past 50 years dad has been milking. I've seen it on other farms.
As far as the 10 ccs sub-Q. There was a young female vet years ago that came out to treat a milk fever case (back before we started treating all of our own cases). She had learned that and so she was painstakingly putting 10 ccs in each spot sub-Q.
With the calcium sub-Q by the shoulders, you don't need to break it up that small. It is going in fairly slowly (not as slowly as IV is required to go in) and when done properly you are beween the layers of skin and the muscle. Skin is very elastic. It quickly works it's way down anyways. With Priscilla, you couldn't see where she had been treated less than five hours later.
You can overdose with calcium. They will flush the system of the calcium and go right back into milk fever again. This is why we prefer the slow release of sub-Q and only giving out cows one bottle and not the two that most vets insist on.
