We've one his son's daughter already cow, the 2nd calver and she probably is the easiest calver. This year she'd 99lbs heifer calf, calved very fast and easy.
We make record of every cow or heifer when she is bred and when she should have a calf, of course if we see when she is cycling, because during summer they're with bull and just 4 now is AI'ed. Also we go everyday to cattle's pastures and always see if cow or heifer is going to calve.
we try to bred heifers just when they're about 1100lbs, but usually they're heavier, for example, this year from 11 heifers just 2 should weigh about 1100lbs, while others are heavier- about 1300lbs, a few the heaviest ones about 1430lbs. Last year we've sold to slaughter 6 heifers: the youngest 24 months( she's calved at 20 months, but calf was dead, so she wasn't the heifer) weight 1146lbs, 25 months old heifer( out of cow which produced slow growing calves which usually looked more like half dairy than 3/4 beef, so we've sold her last year too)-1200lbs,28 months old heifer- 1448lbs, 26months old heifer-1430lbs, 32 months old heifer( she spent the whole summer with bull, but still didn't get in calf)- 1418lbs, 26 months old heifer-1314lbs.
We don't really worry about how our bigger heifers'll calve, because one is AI'ed by Angus, others still growing and will be bred by Limousine bull.
One funny thing is that usually our heifers like to have as heavy calves as cows have, even if they've Angus calves.
