Not in NAT herds. All matings occur between 2:32 and 4:18 PM. Peak heat of the day. Change the breeding season to summer and you'll have 100% opens. Many of your black cows will spontaneously combust, too. They'll dart from shade tree to shade tree to avoid the blistering heat and all of a sudden, WOOF! a giant cloud of smoke and a pile of roasted innards everywhere.
Breeding in August can't be done. Don't bother.
Best quote I've read in awhile. For what it's worth I was "warned" about cows not breeding in the heat of August. Our conception rates have done nothing but get better and we have a tighter calving period than ever. Last year we had 5% opens and of the 95% that were bred only 3% aren't going to calve in the first 40 days of the calving season. You guys with humidity might have different results, I don't know. Another question I had for the OP was the heifer calving in March comment. We're calving heifers right now but I think we might move bull turnout another 10 days back, like about July 25th. Cows to August 10th. If I was you I would back ground your calves and keep them till after the first of the year. Always a hot market for green steers. Resist the urge to put a bunch of weight on them. They will sell better.
