Spring calvers bulls in for 12 weeks. Not sure why, just they way we do it and seems to work. Scanned last week. All 11 heifers & 59 of 60 cows in calf but usually do have 4 or 5 stragglers in those last 2-3 weeks.

Have autumn calvers too but bulls never come out from them until turnout. No bull pens!!
Still waiting on 3 of them from 50 to calve. Last one usually before Christmas.

Bull was out 14 wks with the main group here this year, actively trying to reduce it. Historically been a very spread calving, had atleast one cow calve every month a couple of yrs ago!
Heifer group is about 4-5wks ai (1 or 2 services) then aim 6wks sweeper bull. Although that is longer this Yr due to running Mrs Whitepeaks longhorn cow with them who calved late 🙄
 
What i dont get is when a cow loses a calf folk say it has to be culled cos you cant carry passengers so they buy a bulling heifer to replace it which is a passenger till it calves.
Might as well put the original back to the bull unless it is faulty.
For me it would depend on why she lost the calf and what age she is, if a cow is in the latter half of her career, it's sometimes better just to let her go rather than keeping her for a free year just to have a couple more calves, I've found that weaning weight starts to reduce once a cow gets to around 10yo

If you calve tight there's a good chance there will be a calf for her.
If a good young cow loses a calf and there isn't a twin for her I'll sometimes lift a calf off a cow that's going to be culled in the autumn, that way it saves keeping a cull cow for an extra 6+ months.
But again that's more likely to coincide if you calve fairly tight.
