Care to share what some of those may be? I had some issues last summer on breed backs. It got hot here the first half of May. Turn out was Memorial Day to July 25. Hot, humid, and miserable a lot of that time. 6 of 10 calved in March. Of the four left, I can maybe make excuses for two of them. They are:
8 yo, good cow, raises one of the best calves when she calves. I've rolled her once. I think she's got some ovary problems going on, she's going to town
3 yo, trying to breed back for second calf, was preg checked wrong (actually a second stager in a 3 head group of what was supposed to be all third stagers. She may have not had enough time, MIGHT giver her another go.
Two more 3 yo that dont have an excuse other than the heat and fescue. Of those two, one never shedded much and looked rough all year. I don't think she's going to be a fit. She's going. The other may go too, I don't know that she's impressive enough to give another go.
However, idk how many in the fall group would "fit" either if they were in that spring group.
Multi species (clover, weeds) fescue pasture, good shade and water. Hills too steep to cultivate to sow non/low endo, erosion would be worse than the fescue.
My best weather here is in the fall. I don't want any calves in Aug, although I have had some a couple weeks early come in late Aug. Too hot, too many flies. Mid Sept to mid Oct is what I'm shooting for. I had a first calf hfr not breed back fall before last out of 31 hd. The bull got out in March and she calved last of Dec, so she still calved. Other than the old cow mentioned above, that's the only one in a few years that I have not had breed back in the fall.Turn out Dec 10ish to mid Feb
