Except for this past spring, when we were calving out cows in a progeny-test breeding trial, and had to collect birthweights as part of the deal...I'd only ever weighed big dead calves.
I don't give a rat's backside what they weigh, so long as they get here alive. A dead calf has a distressingly low weaning weight.
I don't feel the need to brag about how big or small my calves are at birth. Alive is the most important thing.
I can't look at one and say, "Oh, that one weighs 75 lbs" or "That one weighs 50 lbs". Never been any good at guessing weights...and I suspect a lot of folks who claim to be spot-on would be embarrassed if they had their guesses compared to an actual weight taken with a scale.
I'm old enough that I don't care if I never have to pull another calf.
That said, I don't pay much attention to BW epds - or the bull's own BW. I do look at CED epds - and rely on them, if the bull has high accuracy. If the bull has a high CED, but BW above what's generally 'recommended' for heifers...I'm generally not too concerned - conformation is more telling than BW, IMO.
I even use relatively high CED bulls on mature cows (again, I don't want to pull calves)...but mainly look at WW & CEM epds on the old girls, as I'm almost always breeding for the potential replacement female.
Used an extreme calving ease/low BW Angus sire several years ago (NBPT D806) - they fell out of heifers, looking like drowned rats - jumped right up and went to nursing - swear some were reaching for the teat before they were all the way out - but if you disturbed them within the first day or so before they had a chance to really bond with the dam, they'd jump up and run a mile, like a spooked deer. PLENTY of vigor for a low BW calf - but sure didn't have much 'grow' to 'em.
But, those heifers got to calve out easily, bond well with their calves, and learn what they were supposed to do to be a good cow. Ol' hbrdv calls those tiny little calves a 'coupon' that gets that heifer a ticket to stick around for another year - and I like that idea... but, I'm probably not gonna breed all my heifers to a Longhorn bull to get that 'coupon'.
