[QUOTE="Son of Butch, post: 1434935, member: 14585"] Break a corn cob in 1/2 and that will give you an approximate size of a cow's cervix. A virgin heifer's cervix will be smaller, ranging from the size of your little finger to the size of my middle finger. When A.I.ing a heifer with a small cervix rather than grasping it and holding it in my hand, I've found that pinning it to the pelvic floor and then working the rod through it works well for me. When a cow is in a good heat the cervix is firmer and easier to find then when practicing on a cull cow that is not in heat. It can be frustrating as a beginner trying to locate the cervix when it's soft or mushy. But I assure you all cows have one, so just relax a bit, take your time and you will be able to locate it. Often it's not as far in as many beginners guess, so it's common to reach in too deep and search for it too far in... where it's not. But each cow is a little different than the last. [/QUOTE]
