[QUOTE="dun, post: 42703, member: 34"] I don't feel that it's a heat tolerance issue, but heat does cause fertility problems. Excessive heat, whatever that may be, decreases the quantity of viable sperm, and excessive heat around 2 weeks post breeding can cause failure of implantation. The cow that stands around slobbering and heavy panting is having problems with the heat. We have had black and red cows that have the problem. But we've got blacks and reds now that don't seem to be particularly affected. Two heifers we're finishing right now are panters. One black, one red. Both of their dams have no problems with the heat. These girls, sired by different bulls just can't handle it. They'll work well in the freezer though dun [/QUOTE]
