Source-verified means you know where cattle come from. Maybe, if, by knowing the source, you know how they are handled. For instance, if feeder cattle go through some special backgrounded sale, and the sale requires certain management and health procedures, then you know what the process was. But merely knowing the source of cattle might be worth little, if anything.
Some people now have some small-grain pasture.
Other research has shown that grazing small-grain pasture 2 hours every day also works well. There is some thinking that implanting stockers reduces feedyard performance or carcass merit. Steers then were fed to approximately 1200 lb. There was no significant difference in feed consumption, feed efficiency, or average daily gain. Also, carcass weight, marbling, quality grade, fat thickness, ribeye area, and yield grade did not differ.
