Your Jersey cow would still have a chance, but milk fever is mostly affected by environment and feeding during the dry spell. We very rarely deal with milk fever cases and we have a herd of Jerseys and Jersey/Norwegian Red crosses. Even the few cases we have are not a huge deal. We treat them sub-Q and the cow is good to go.
The dam's body has a lot of say in how big the calf is going to be. Jerseys are known for their ease of calving as well.
The school ran a Hereford/Limousine bull with the open heifers (some not even two years old yet) and open dry cows. Haven't lost a heifer yet and the first ones to calve had just turned 2 years old. Out of about 18 head that have calved so far, two calves born dead (one had to be pulled) and two total pulled. Those were out of first freshening four eyar olds though. The issue there is they are too fat.
Angus is a popular choice.
We ran an Angus bull for clean up about five years ago. Only one dead calf there and it was out of a 21 month old first freshener (she didn't agree with us when we thought she shouldn't be bred that young). The cow was fine, the large bull calf was born dead. Only one we lost that year.
