[QUOTE="rockridgecattle, post: 794579, member: 6198"] Heat, drought, excess moisture do play a part in open cows. But so does body condition post calving and so does a proper mineral and nutrition program. High open cow rates now could and very well might play back to the summer of 2009. I say this because this is the hay and or grass they were fed during the summer and winter of 2009/10 and this would determine the body condition going into the last trimester, the ability of the dam to breed back on time. Poor body condition, or poor feed or lack of mineral then will leave open cows now. Everything that happens to a cow in the here and now will have short term effects when the calf is weaned, but the long term effects will be felt for another year or two. And depending on the severity of the weather/nutrition problem, might even be a third year before things go back to normal. So, if you have open cows now, look back the previous year's mineral consumption as well as the pasture conditions, the quality of hay that was put up, the ease of the calving season, thriftiness of the calves that hit the ground, the scour and summer pnemonia issues, and the wean weights of the 2010 calf crop. Open cow spikes don't just happen, there were warning signs that lead up the the open cows that just got missed. [/QUOTE]
