"Forward contracting, which consists mostly of basis contracts between packers and cattle feeders, represented a small percentage of fed cattle procurement each year. Forward contracts averaged 3.5% of packers' procurement for the three years. Packer ownership of livestock, one of the most discussed components of captive supplies and a frequent target for legislative reform, accounted for 7.1% of total fed cattle procurement on average for the three years."
From what I constantly hear, I would have belived these numbers to be higher than they actually are.
