Best Genetic Decision - When the TH and PHA defects came about, we tested all of our cows, culled all carrier cows, and only used clean bulls from that point on. Luckily, we only had 1 or 2 carrier cows, so it was not much impact to our operation.
Best Non-Genetic Decision - Though still somewhat genetic related, but we stopped using "clubby or steer-sire" bulls. Our birthweights went down which made calving season much less stressful, and by focusing more on seedstock genetics, it does not matter if we get bulls or heifers any more, both are just as easy to market.
Completely off subject, but it makes me proud to say that this post is #1000 for me. I am happy that this is the topic that put me over the top. We have felt strongly about both of these decisions in our operation. It was the right thing for our operation, and we feel it is the right thing for the industry.
