Happens more often then you think. Some version of low libido I reckon.

That said, my money is on the bull dynamic. Heat stress or injury to the bull combined with small heifers that may not want to be crushed under his weight. Eventually it becomes not worth the work (especially at 107 degrees).

We have lower conception rates with our two Spring herds than our two Fall herds. Like 80-85% compared to 95-100%. We have tried everything in the world to improve conception with the Spring herds but we (vets and local guys around me) keep coming back to heat stress on the bulls. Pretty hot and humid for the boys in June and July. Same bulls used for Spring herds and Fall herds and plenty of redundancy (usually an extra bull put in with each herd). BSE performed 1 to 3 weeks on bulls every time before turn out. And breeding heifers has its own challenges with conception.

My bet would be on heat stress.

Thanks everyone for offering suggestions. I realize I may never know the cause of the high percentage of opens. I have bought a new bull to put on this next years heifers and we're going to build some sort of shade in this pasture for cattle comfort. Other than that-it's business as usual. :deadhorse: :tiphat:

We have shade screens in a number of pastures, not as good as a big ole oak tree but it does give them a bit of relief. 2016 was brutal here and we had more open heifers than normal.
