We do several different strategies according to what the markets are looking like... and what we need to retain to put on pastures. Some get sold off the cows but more get weaned and fed for 45-60 days...
Looking like we might be selling some off the cows here real quick with the prices being as high as they have been..... But... mostly our markets here will bring a little better prices for weaned, bunk broke, and calves with some sort of vaccination program behind them. On top of that , we buy some of these odd bull calves, and bring them home, castrate and give some shots and then can mix them in with others, and ours, if they match, to make bigger groups. It's a crap shoot though now to buy any and then you worry about losing a bucket full of money on one if it dies.... even the "cheap ones" are pretty expensive to bury.
Last year we did not keep one steer to go out on a place we usually run steers at, so we retained more heifers and pastured them. It might be that way here this year again.. holding back more heifers to graze at leased places where we have to put something out on the grass.
We also have 2 basic calving seasons, spring and fall... Mar-May and Oct-Dec... 90 days each but most calves are born in the first 60. Since we also buy a few cows here and there, the lines get blurred on calving seasons and we will hold a cow over if she calves in the summer, to go with the fall group, and have had a couple calve here this month and they will get held over to go with the "spring calving " group... so their calves will be a little bit bigger and older... Gives us the flexibility to match some up... and cows that calve outside of our window, will get a chance to get bred back as soon as the bull goes in and therefore get right on track. Anyone that doesn't get with it and gets bred back to fit in the group, does not stay now.
There have been a couple of old cows that have had phenomenal calves and calved regularly, that have gotten a break and got held back if we are trying to get another heifer out of them... but they have been few and far between over the years....and right now I don't think there are any like that on the place. Even shipped 2 old cows that were less than 60 days bred, in good flesh, and ornery dispositioned...they always raised a calf but were way behind this year and decided it was time to go while they were up and healthy and walking and in good flesh. If they had been bred along with the rest would not have thought twice and kept them again... This one place it is not feasible to get the bull out at 90 days so occasionally there will be a few that are shorter bred.... then it is a judgement call with all factors taken into consideration.
