We use both crossbred and straightbred bulls.
We weigh every calf, every year.
I can fully document that there is absolutely no difference in performance or uniformity of calves resulting from either crossbred or purebred bulls.
There are differences occasionally for traits like horns, scurs, brindles, but never for the triats that count, like fertility, and weight.
My guess is that there isn't a single person on this post other than me that has actually taken the time to get the help to make a statistical comparison.
Everybody always tells me that the crossbred bulls will make for more variation. My records over the last 15-20 years says they are dead wrong, or full as a Christmas goose, as was said earlier.
I've had crossbred bulls produce less variation, too. Some more, some less, average is that there is no difference.
Seriously, I have had folks call me a liar with my records right there in front of them.
I took my data to my local math teacher for a start, now with the internet, it's pretty easy to lean how to do the stats.
