A. I. Heifers.
Yes, we track the bull and heifer info in a fancy spreadsheet.
But next spring when we are riding through the calving pen I probably won’t have my laptop handy.
It is just so easy to glance at that red heifer’s ear tag, see that “R” and know she was bred to the bull called Redemption.
Redneck Record Keeping, no doubt about it.
Beef Matters 
I like this post. We don’t AI, but when we preg heifers, I have a notebook and keep all the info in that. Her attitude, breed etc. Put it on a spread sheet and in the tack room. When we calve out our heifers, you can go to the list, find her tag number and record baby data. date, time, weight and other notes. And I always have my “palm” pilot and pen with me! LOL. I look forward to following your blog.
