So we have one vote for each of us! I should have included a poll in this thread, LOL.
I'd have to check but there's a good chance we used the same bull. (We get recommendations from one of the semen companies we buy from.) Our cows aren't registered or anything, so it isn't really important -- I just thought it was an interesting situation.
#665 happens to be my boss' favorite cow, and one of my favorites as well. She is the biggest Holstein I've ever seen!

And, having been a tester, I've seen thousands. I call her "the Sideways Cow" because she has to stand diagonally across 2 spaces in the parallel parlor to be milked, and then we have to back her out because she's too wide to fit through the spaces. She is friendly, smarter than the average cow, and always in the last group to come into the parlor, and her daughters are carbon copies or her.
This is her 5th calf, and four out of the five have been heifers. Her oldest daughter washed out in her second lactation after a difficult calving; second daughter is in the milking string right now (in fact, she's my favorite); third daughter is still in the heifer barn, and now the new calf. So far, her daughters also have shown a propensity for having heifer calves. I told my boss that at the rate we're going, we're going to have a whole herd of oversized cows with interesting personalities. He grumbled, "Yeah, just what every dairy farmer wants .. "
