How much influence does a bull really have on birth weights? You would think 50%, but it seems most of us focus 100% of our attention on the bull when considering bw. Just thinking out loud. :?:

If you breed them to a low bw bull and they throw large calves, what would happen if you bred them to a larger bw bull that could increase weaning weights. Would the birth weight stil be about the same since the cow seems to have the prepotency for certain size calves, or would the cobination of a large bw bull and a large bw cow cause you to have an extremely large bw calf???
I was worried about birthings this past season. The brother-in-law was in charge of feeding the cows. They were being fed too much grain. I couldn't seem to convince him to stop feeding so much(he was feeding in the morning when I was at work.), and the cows kept getting fatter. Luckily we did alright. Teh feed wasn't all that high in protein, but the cows were getting too fat. Since then, I've been feeding and gotten the excess weight off them without any problems. Now they are all in the 5-6 bcs range, not 7 and 8.
I have bred for F1's, Brahman cows with Hereford bulls. I have never had to consider wither the bull was high or low birth weight.I do not recall any calf over 80 lbs. I have talked with others that have used Brahman bulls over Hereford cows and they say they have to watch heifers pretty close.ArmyDoc":2m368dg6 said:No personal experience, but have read that in the bos indicus breeds the cow has a lot of influence on the calf, and consequently have much less trouble when bread to large bulls, where as in the bos taurus breeds the cow has much less influence and can get into trouble.
