When I choose Char bulls, either for my white heifers or black cows, they have to meet 3 basic criteria; calving ease (70# to 75# birth weight)
I'm all for ease of calving but if we go to the extreme of selecting Charolais with bw of 70-75lbs aren't we selecting for what an "Angus" should be? In the great breed identity switch we have had the Charolais calf can now weigh 70-75lbs but an Angus can weigh over a hundred :?
The last Charolais bull I had was an 84lb bw but I'm sure he sired plenty calves over 100lbs out of the larger crossbred cows. I used him for 7 years and never assisted a calf. I believe there is a lot more to calving ease than the bulls birth weight. I don't believe half the bull birthweights you see quoted anyway. Look at how some populous breeds have increased growth and mature size by huge amounts yet the birth weights haven't wavered. :roll:
Well of course there is more to calving ease than birth weight, but still it's a solid indicator don't you think? If my average birth weight is 75lbs naturally your going to have outliers on both sides. I've seen calves from 65 to 95 lbs but having the bulk being an average of 75lbs.
Harris25 is asking about char heifers and angus cows. I certainly wouldn't give him the advice to go buy a 100lb bw bull knowing that outliers of 120 lbs. are probably going to be a reality. If I did the suggestions & comments of him having good credit at the vet & industrial strength calf pullers would be right on.
BW hasn't wavered? You're telling me you can go buy any angus bull & put him in with your heifers? I can remember dad & grandpa's mature angus cows that would barely weigh 900 lbs heavy with calf. There's been migration of weight, frame & corresponding increases in birth weights as the respective breed organizations have modernized cattle and chased specific traits.
I guess in the end what I'm saying is that the genetic potential of individuals combined with cross breeding is greater than having heavier birth weights, IMHO. 8)
