New Mexico | you may have over fed the hiefers during gestation.
Another huge factor:
The hiefers themselves are half of the genetic equation.
( What did they weigh when they were born?)
On birth weights, the hiefers themselves are more like 70% of that equation due to mitocondrial dna and bw "carryover" factors.
On hiefer development, most folks tend to take to good of care of the hiefers.
They don't make those hiefers get out and do it ( rustle feed and water ) on their own.
Only time that hiefer may need a touch of supp feed is the last trimester ( while walking a mile between feed and h20 daily ).
There's alot of genetics out there bred for pure yearling performance ( 100 to 120lb epd ups on yw ).
There is no way the afore equation does not also increase birth weights quite drastically upward over time.
btw, Which bull did you use on these?
What was his ACTUAL bw?
What was his dam's actual bw?
What was his sire's actual bw?
What was the bw accuracy and on how many progeny?
The ced epd generally reveals more predictable calfing ease vs the bw epd. MO
