I had a cow rebreed 3 weeks after calving before. It depends how easy the calving was and how good of condition the cow is in.

Before you buy, get her palpated by a good vet and see if she is pregnant and if she is, should be able to give a pretty good estimate of how far along she is.

How soon can a cow get bred after she has a calf...

She will normally cycle again within 21 day or so, and can settle on her first post-partum cycle.

That varies, too. With a heifer, that means almost nothing. With an older cow it can be a little better indication. How bout the back end? Is she starting to get a little slack?
It is exciting to start seeing those signs. isn't it?

If you want a calf every year (365 days) then the cow must be bred by: 365 - 283 gestation = 82 days after calving (max)

If you want to allow two cycles to get bred then 82 - (2 x 21 day cycles) = 40 days.

So by this logic you should put the bull in with the cow about 40 days after calving to insure a calf every year. I put mine in at about 50 days from first herd calf this year

If you don't put the bull in about this time every year your calving date will gradually slip back further and further which is generally not a good thing.

I'm going to respectfully disagree with your logic. I recommend putting the bull in when you want to have your first calves. Putting the bull in 50 days after you start calving will get calving started earlier every year. In a northern climate that won't fly. If you run a good program there will be no slipping in the calving dates. In most herds there is a very high percentage of cows calving in the first cycle once the bull is put in. I don't know my percentage for sure but I would say 75% is the minimum on any given year.

I very much agree with you. All of my calves were born within a 21 day period this spring so my bull bred all of them on the first cycle. I we assume first cycle catch then to have a calf on the same day next year would be 82 - 21 = about 60 days after the first calf this year. I was trying to be conservative. Do most cow calf operations have most cows catching the first cycle? Seems like many times I hear about 60 day calving seasons which would be way to long for me.

In addition to building a bag, the vulva will enlarge as calving approaches (extension says 1 to 3 weeks prior). We say they're 'springing' or 'getting slack in the back'. This is more visibly pronounced in some cows than in others.
