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
