I thought that was common knowledge. Dr. Lisa Kriese-Anderson at Auburn used to beat this into our heads at every Beef Cattle Improvement Association Meeting & Workshop..
Here's a quick google reference:
Productivity pillar: The goal here is to increase production efficiency by 15 per cent. Fat is added to an animal at a cost of feed roughly 2.5 times that of adding muscle. To make the math simple, if we use a feed efficiency of 5:1 for muscle (12.5:1 for fat), this additional 62.6 million pounds of fat equates to 391,000 tons of grain. It also results in a tremendous amount of both more manure and greenhouse gas. For both industry efficiency and industry sustainability, excess fat is a huge problem.
