[QUOTE="farmerjan, post: 1545239, member: 25884"] I think it has merit. And if you keep heifer calves out of these lbw bulls. and then breed them lbw bulls. the resulting generations seem to get smaller. We have kept some heifers out of first calf heifers that were bred to lbw bulls. But I make it a point to try to not keep any that seem really small even if they are nice. We do not do registered and don't sell bulls, so not like some of you farmers that do. But I tend to not keep too many heifers out of heifers, and we have several plus wt bulls that we use on our cows so we are not "breeding smaller". I have not noticed the heifers calving that much on a shorter gestation, but don't doubt it could be true. We mostly pasture breed, and they usually have these nice "little calves" but most all have been up and going quick as wink. One thing too, we calve our heifers out a little older than many, they are 27 to 30 months when they calve usually. So maybe are not seeing the "smaller weaker" calves that a younger heifer might have. KNOCK on wood, have not lost a calf out of a first calf heifer in years, except for one the coyotes got at about 3 days old out at a pasture where they were seeing packs of them for a few weeks. Had the blk basturd buzzards try to get one a year ago, when she was just up and trying to clean it, and we saved it only because someone was there... 30 minutes she had that calf cleaned, up on it's feet, nursed a little, and taking it off into the woods.
