For those who don't run your bulls year round, what is your average calving window? I know everyone shoots for 66 days, but what are your real world results?

I ran two calving seasons here in Oklahoma. My spring season would drag out to 75 days if I didn't pull bulls. Fall was sixty and the majority of the calves were in a 45 day window. I've had a lot of customers over the years that would do timed AI and get to the point that after a couple of years they'd sell anything that didn't calve in the first thirty days. Once they would get to that point they'd only have a handful that were bull bred in the following years.

We start calving our heifers (1st and 2nd) for a January 7th (ish) date. Which means we get our early ones around Christmas Day.
Our heifers calve (if AI’d) for two weeks. Then we start calving our cows. We’ll calve everything till 1st week of March. Then they go bred, to sale barn. Which serves us well because most everyone else around here starts calving then.

Last fall was 9/2 to 10/29 (23 hd or so), had one open (second calf)that bull bred when he got out a couple months later and she calved on 12/30. Spring cows, only 6 hd, calved in 13 days, had some opens though that I rolled one time to fall. If they dont get it this time, they're out. This was to be their second calf

Came awfully close to 60 day calving this spring with the exception of 3. Started 2/21 and 43 had calved by 4/21, 2 lagged and calved by 5/10 and I had a first calf heifer drop hers 6/16. Have no idea why she was so late because I had her down for mid March but I suspect she aborted & bred back. I culled pretty hard last year to get back to spring calving only.

You think you can move her back into your window? Might take two seasons if you put her in with a bull but you’d get pretty close. |

I have 2 calving seasons, both roughly 6 months long.

Bulls are out now and I won't pull them until 4 - 6 weeks before weaning, prob late Aug/early Sept. In a perfect world I wouldn't want her to breed back so quickly as a first calf heifer but my world is less than perfect. Her mama was a prolific breeder; lost a backward calf one year (I didn't get there in time) and bred back immediately so I still got a calf out of her that year. Of course that just added to my year 'round calving and I finally stopped moving the bulls back over after weaning, pulling them after the start of calving & putting them back towards the end of May. |

59 day calving season on cows. Half of the cows got AI'd rest went to bull. Heifers started March 6th and they wrapped up on the April 1st. 26 day window on them. Get's easier every year! We culled 1 open heifer and 1 open cow last year on 45 head we exposed.
We AI'd June 1st to the 13th on cows and heifers. Actually do cows first. Will pull the bulls if weather and time allows July 25th on heifers and first week of August on the cows. Preg check first week of September and opens will ship the first Thursday in October when calves are weaned/sold.
We used to have 2 calving seasons so I needed a break and now only with spring cows I'll never go back to calving much over 60 days!

Bulls are out for 45 days on heifers and 65 for cows. Turns into about 75 days when it’s all said and done. Last year we were 80% done on first heat cycle which was great other than the blizzard every weekend for two months straight.

70 days, on 200 plus head, usually have 115-120 calves in the first 30 days, usually starting Sept. 15th. But always have some that hold way late.

60 days is what we shoot for. We don't pull the bulls until well after they should be done breeding so use the vet's expertise to tell us the ones that are outside the calving window. We were all finished but for one cow at 63 days this year so I figure the vet did just fine.

Wish I could find this calving window. Can you open and close it to let calves in or out?

In a previous life in a big, rugged environment I left bulls out 120 days and like Silver, relied on the DVM to determine long breds & short, keeping the former and shipping the latter. Several years ago relocated to a small farm. Breeding season is 45 days with the majority calving in the first 2 weeks.

Well, she definitely got bred yesterday, both bulls tagged her. If she settles she should calve 4/24/20. |
