I agree to see if you can get some bucket cow milk from the dairy until your cow calves. If not, use the BEST milk replacer with all milk protein... NO SOY..... and when the cow comes fresh, mix the bottles for 3-4 DAYS half and half so as to not change them over suddenly.
Changing milk to replacer back to milk will cause some problems.... FEED LESS... for a few days so they are hungry and don't get overloaded with whichever formula you are feeding. Like 3/4 bottle a feeding.... watch their manure close.
I am assuming since you said nurse cow, that you will be putting the calves on the cow???? Then you really want to give them some half and half mix for a couple days while the jersey is producing colostrum, plus it will be richer than the replacer so will take a little bit of adjustment... that is why I said to mix it. I will mix milk replacer in when I get short of milk from the cow....
