  I thought it would be fun to put this up. Seems like there are some young producers that wonder how long to wait B 4 getting concerned about late AI due dates. Of coarse we all know that different bulls have different ges. lengths. These were all mature cows that I synced with 1 shot cystrelin @ the time of putting in a cidr for 7 days & @ the time of pulling the cidr I gave 5 cc of Lytalyce, then started heat cking. & bred off of standing heat. Actually put in 20 cidrs. Bred 1 cow naturally caught in on the 1st of July,(she happened to calf last out of this group on the19th of April). One cow lost her cidr & showed no signs of heat and was later reset bred 2 times, didn't settle ,& was sold. Another cow had her cidr in, but no response, set up later & bred, settled & is due on 5/14. The rest of the cows are as follows.Pulled cidrs on a Thursday afternoon, early evening. Started breeding Sunday evening. Bred 15 that day,which was 7/2. Bred 1 on the 3rd, & 3 on the 4th.
5 cows calved on 4/4, that's 9 days early on a 285 day gestation table
2 cows  on the 7th, 6 days early
1 cow on the  9th, 4 days early
3 cows on the 10th, 3 days early
1 cow on the 15th, 2 days late
1 cow on the 16th, 3 over
And again the cow bred natural, 1st cow bred & last to calf on the 19th, 6 over
Of the 6 cows that recycled. I had one 9 day wonder, bred her 2 Xs, she reycled, sold
one recycled 2Xs, sold
4 rebred on the 1st recycled from 7/22 to 7/25, Am ecspecting to get 4 calves from 5/3 to 5/5. We'll see how that works out for me.
  I liked the way it worked last year, because I got 2 swings out of it in approx. 3 weeks. All AI calves, but had to sell 2 coes, which happened to be older. Going to set the mature cows up for Sunday the 1st of July this summer. CAB

For our cows that actually stuck to AI and had calves last fall, below is a list of the actual time from breeding to calving (14 hd with definite AI calves):
261
271
273
273
276
275
275
275
280
280
283
283
283
284
AVG=277

It was extremely hot and dry down here last year and everything seemed to calve early.

Cleanup bulls were thrown out a week after AI.  For cows that we AI'd but did not get "stuck", they calved at the following time from date of AI (just to illustrate how we were able to tell whether we had an AI calf or cleanup bull calf):
299
313
313
312
312
312
323
346

There was a clear break between the date of the last AI calf and the first that was born to cleanup bulls.

wow, great records guys! I'll have to check mine but we were generally early this year.
Oh course, also had all heifers.

  Interesting, when you look @ Frostbacks gestation length, it stands out, that they really get tight around that 282-289 area, but 10 days early & 10 days late re4ally common. For everybody that is always wondering about how long??? It would be interesting to go by breeds & bulls to figure out gestation lengths. I have only had 5 Cowboy Cut calves, but I think he could be a short gestation length bull. Started on the 2nd round this morning. A cow that was bred on 7/2/06, recycled & was rebred on 7/22/06 calved 4/26/07. I think that is 8 days early. Have 3 Radio Actives coming soon, they look to be longer term. I haven't have alot of previous experience with SH, but aren't they longer in general? Have one old broken down Simi X cow that is bred to Sunseeker, she always has a early small calf that I don't like that usually rises to the top B 4 fall.
  On one of my previous posts, I asked for the best PHA & TH free bulls to use that can compete. What I was also kind of trying to show was that until we can come up with one that will, us club calf freaks will use what will work  & sell. I know it doesn't make any sense to alot of people, but it's the total reallity of the situation. I find it abit more amasing that we use Heat Wave & his offspring, when we are pretty sure that the heirfers probably won't end up milking even close to well enough.
  Does anyone have any thoughts on the Open Bar bull? He does interest me. The Black Impact in the pedigree, how much will it pull down the milk & maternal values? CAB

I actually have 2 Radio Active calves in my data 1-279, 1-283 and we had one AI at 281. 
If you'll notice in your previous post, you didn't really get a response at all that had a clubby bull listed.  We breed to Heat Wave hoping for steers, the heifers are just a casualty of trying for the great steer.  Let me know how your Radio Actives turn out, our are not quite Heat Waves, but they are pretty darn awesome.

Just went through our records today and man did the weather cause chaos with our expected calving dates!  ::)

Our cows that were AI ed and stuck (no bull in there for more than one cycle) ranged from 248 days to 299!!!!!  Yes, there is an obvious correlation between the temps and barometer and the calving records.  Isn't that special?  We still ended up with an average of 280 day calving cycle even with all that variance.  I should look back at old records but don't have the time to do it tonight.  Wonder what a long term trend might reveal..... ???
