Here is a six year old bull that is the one of the six bulls we bought at their final production sale. We have three left, and had all six until this fall, as they had great longevity. None got nasty, or were fence crawlers. We bought bulls 3 different years from them, and it was one of the best things we have done. The three we sold this year were still sound, but we felt it was time to replace with a little younger bull. Our coming three year old's were strictly bred to N- bulls for quite a few years, and they just calved so easy it was unbeliveable. One year we had 130 3's or somthing like that, and they were calved in a 1000 acre pasture. We checked them once a day as usual, and we only had one dry cow at branding, and she had aborted over the winter. Anyway, I just could not say enough good about them.
