Yes but I'd give him an extra couple of weeks.

Could be, good chance, might be, should be, probably. 
TTs right. A couple more weeks would be best.

When you use the word "bred" do you simply mean "screwed"?? If not please differentiate between "bred" and "safe in calf"??mwj":a7qp2gfq said:

Some could potentially cycle twice while others only once. If it was absolutely necessary to pull the bull at 1 month, I guess you could sync the heifers so they all got a chance to cycle twice if needed.

You will wind up with open heifers if you do sync them. Bull might get them all covered but he might hang with one or two and miss the others. If you sync just go ahead and try and AI what you can. That way you know they all got a shot of bull juice.

Not saying it would work 100% just saying he would get a second shot on the ones that needed it.

Bovine heat cycle is 21 days. Do your own math.

Why not just sync them and throw the bull in .

I should have clarified, sorry. I was just curious on that time frame ? but the bull will be left with them 24-7 until I sell them as bred heifers in late summer or early fall. I blood test check them and it's 99% accurate. I'll probably test them in July.

72% in calf first cycle, another 65% by second cycle, and another 55% on third cycle, and another 50% on fourth cycle, for example - leeds to 7 calving in the first 21 days, then another 2 in the next period. Assuming everything works. Often the first day(s) result in nothing because of too much commotion in the herd when the bull gets there + chance and luck comes into play, a bull can have a bad day or week, heifers with diahorrea does not settle well,one or two may not be cycling and so on. More time with the bull gives more calves. 30 days gives 1,5 chances for each heifer.

Strength in numbers....not always a good thing. Aren't you asking a 2yr old bull to breed 10 cows in 24 hours and settle them all. Seems like he's gonna run a little low on swimmers there.

Yes, I mean the injection of a swimming sperm. If that was all that was required AI would always be 100%.The part that always gets to me, is the question is always about the bull. Not one word about those 10 fertile heifers that just need a whiff of sperm, to start there productive career. :hide:
