Any information anyone wants to know, will be provided in total honesty. If asked.
The key point is, if asked. To many times I have sat at the sale barn and seen owners speak for their cows. We are often times looking at an animal that is average at best and the owner is going on and on about what a great cow she is. To me, they are overselling. Sort of a horse trader mentality.
If I am running a decent bull through because I can no longer cross back into my own, and the auctioneer asks, "Can anyone speak for this bull?" I will answer honestly and briefly. A few times buyers come along with follow-up questions and I take him out and show him cattle in the pens that are the bull's offspring.
There is nothing more valuable than a man's word in my opinion. Secondly, I plan on selling lots of animals in the future.
If the sale barn works on commission, they are obviously wanting to get prices as high as they possibly can.
