The genetic revolution in the beef cattle industry has brought us tremendous increases in productivity. The bulk of these improvements have been realized through improved rates of gain. The U.S. cattle industry enjoys one of the shortest cycle times, the time from when a calf is born until it is harvested, than any of the other top ten beef producing nations. We are now producing more pounds of beef with fewer cows and in the grand scheme that is more efficient. However these increases have come at a cost to our cow/calf production systems.
