I just got off the phone with the Red Angus Commecial marketing man. Dr. Hoss. He was at the Superior Livestock sale held in Sheridan, WY this week. He had the sale results in his hand of how the Source and Aged calves did compared to the ones that were not. They said that the Source and Aged calves sold for a $3.70/cwt premium. To me that is huge. On a 550 lbs calf that comes to $20 bucks a calf. Granted that is a country wide audiance for bidders, I am not sure it would be that much at alot of the sale barns around the country, but I know it would at some. Do many of you use a Source and Aged tagging system?
