Donor Cows With nursing calves?

[TexasRedsAndShorties]

What should I be feeding them mineral wise and feed wise they are on mostly grass and hold their condition very well (Red angus) but what do other outfits do for their donor herds? I have been supplying them with nice mineral blocks and whatnot just a fun question I ask this to gain knowledge on how to give them and the calves they are raising a nice boost

Are you talking about recipient cows with their ET calves here, or are you talking about your donors with their own, natural calves?

Honestly both would be nice to hear about
