My husband crossed holstein to angus and kept the heifers for many years. His recommendation is to give Scourgard 30-60 days before calving. He thinks a char bull would give you too big of a calf, but I keep telling him they've worked on their birthweights and they have some chars with low birthweights (this is the reason he won't let me breed our aged cows to a char).... anyways, the calf will grow like a weed.
It seemed to me that if we had them calve from Oct. to May, they did fine. Hot, humid summer days seemed like they scoured a little easier, but that also can happen to non dairy breeds as well.
We have quite a few holstein x angus and now 1/4 holstein, 1/4 angus and 1/2 red poll and I like those as well. We only have about 40 head, but almost half of them have some holstein in them (1/8 to 1/2). Breedback hasn't been a problem, but I add extra Vitamin E to the minerals prior to breeding time (actually its a bag of Vit. A, D, and E)
Good luck in your endeavors!
