3 days after calving cow became very weak and couldn't stand. By the time the vet arrived (6 hours later) had already died. Vet felt this was likely grass tetany or milk fever and I think he may be right. We had an older cow get down about 2 weeks ago and he gave CPMK and she seems to be doing fine now. This cow looked fine yesterday.
I have 2 questions for anyone who cares to answer. First, can you send Calcium and Magnesium level after death and expect to get a reasonable level (the vet mentioned ocular fluid but didn't bother to offer to draw any levels)? Second, when he saw the cow 2 weeks ago he recommended changing to high mag mineral as we are grazing ryegrass. We had been giving Vigortone 35S mineral and switched to the high mag mineral by Vigortone but the cows don't eat it at the required levels. Any tips for getting them to eat more or any high mag brands that are more palatable?
Thanks for any advice.
