I have 6 cows that are Holstein X Angus. I have bred them and they all have a one month old calf by their side. I notice they seem to thin out a bit more than my pure bred Angus after calving. I assume it also just has to do with the Holstein frame coming into play. Where I buy grain there is either Beef Grain or Dairy Grain. The nutrition guy has yet to call me back about my next order but I am wondering. Would you feed these cows the dairy grain mix? I am not milking them their only job is to feed their calf. They all have massive udders and are literally leaking milk all day.
