I remember when Charolais first got to my area in the early 70's. Yeah, a lot of people had problems using a Char bull with those little Angus and Herefords most everyone had. I did have a neighbor that was raising Santa Gertrudis that used used one on some of his grown cows, without any problem. Bred some Char cows to his Gert bulls, too. But I think there are more CE Char bulls these days. Like I mentioned in an earlier post, I bought some Brahma x Chianina cows from a man who was breeding bucking bulls, a few years in a row in the 2000's, and I bred them all to a reg polled Charolais every year. Never had 1 calving problem out of them, just good white calves that you could nearly watch them grow daily! I also kept some of the heifers some years, and bred those 1/4 Br/1/4Chi 1/2Chars right back to a Char bulls when they were 18 mos old, and never had a calving problem with them either. 1st set of those heifers I kept, I bred to a Brangus..or might have been an Angus.. I don't remember, but they didn't like the smoky heifer calves much at the sale, as the white ones. The steers probably brought a few cents more than the white ones, but those Char-sired steers made up for it in weight at sale age. So after the first set bred to a Charloais, had no more problems than the ones bred to the black bulls, I just used the Char bulls every year after.
