[QUOTE="forageconverter, post: 392413, member: 6466"] Her size should also be taken into consideration in determining her calving ease potential, as well as what is generally acceptable in the way of a bull’s calving ease for heifers. A heifer’s calving ease potential would certainly be harder to determine than a cow that has calved many times. But many people in the industry consider a heifer’s first calf a ‘throw away calf’. They are only concerned about getting a small, live calf, and that’s it. I’m simply saying they are possibly wasting what could be a desirable calf crop. There’s a special heifer sale in our area called the Show-me Select Heifer sale, or something like that. I’m not sure what the requirements are today, but it used to be that the heifers had to be bred to a bull(such as an Angus) that had a calving ease EPD of 6 or higher. I’m saying if a bull has a calving ease of 6 or 7 and has a yearling EPD of +90, I would think it would be better to use this bull on a heifer of proper size and of proper pelvic size, than to use a bull with a calving ease of 11 and a yearling EPD of +36. Likewise with a cow, I would prefer a calving ease of 4 and a yearling EPD of +100 as opposed to a calving ease of 11 and yearling of +36. I think the first bull would come closer to optimizing my cow’s potential of producing my desired end product. I guess another way to say what I am trying to say is: One should focus more on ‘acceptable’ calving ease, rather than ‘maximum’ calving ease; especially when the maximum calving ease comes at the cost of sacrificing other desirable traits that otherwise need not be sacrificed.
