I have 2 Primo daughters left, both among my top producers. When I sold down a few years ago, the others seemed to be the first to go. I wouldn't sell these two. One is out of a Double Trouble daughter. Fortunately for me, she has produced 3 females that are outstanding. It would take quite a bit of talking to pry one loose. The other Primo daughter I have is out of a Double Down granddaughter. I made the mistake of selling her first heifer calf, thinking the cow would have several more. Nothing but bull calves since. Her 2012 bull calf was born October 19th, my granddaughter's birthday. Had he come about 2 weeks later and put in somebody's show barn....Let's just say he's developed quite well. He's sired by my Bloodstone son. Seemed to have worked. I really like Primo crossed with Double Stuff line females or some with another shot of Maine. He has been very good to use on heifers in my herd. I don't think he downsizes and needs to be used on females with good rear legs. He didn't improve rear leg structure on a few of my females, which surprised me. On the other hand, I didn't get any bad legged calves out of good legged cows. I would use him on a big bodied, big hipped, heavy boned female of moderate size. The front ends will be pretty, you'll have a moderate framed calf made the way you like, in my opinion. I still have 20 straws or so that I'm planning on using on the upcoming Zulu daughters I'll get.
