JTM I think if you go back and look at your comments it appears that you think JPJ cattle have no place and are not low bw. I believe you whole heartedly when you say these genetics did not work for you in your program/environment. However, I have had the complete opposite where he has done wonders in reducing both bw and mature cow size. So, if you would have stated it as if he didn't work for you but may for someone else that may not have received such blowback. I will agree that he does not help in the growth department but, you have to realize that everyone's herd is at a different place, i.e. some may have bred in too much growth some may have over bred on low bw etc. So, again what may work for one may not work for another.
To the original poster what are your goals with the resulting Calf so, myself and others can help direct you towards genetics that should work for you?
I'm glad he worked for you and you are correct in your analysis. Unfortunately in our breed we have all kinds of inconsistencies and we have pretty much about 5 different breeds of Shorthorns within our small breed. If we were a larger breed that might be alright but if we want to gain commercial acceptance we need to have consistency and zero risk for the commercial customer.
From my experience Proud Jazz did not improve udders enough,
did now down size mature "weight", maybe frame score but not "weight", and his birthweights would still jump over 100 on higher BW genetics on bull calves. I just believe there are a lot of bulls that are better options to improve the breed that people passed on because they didn't have the popular eye appeal that JPJ had. That's the problem we have. Choose by eye appeal and you give up a lot.
