seminolewind,
It looks like your chart was based on human nutrition and the chart doesn't state the TDN, NEm, NEg, NDF, or ADF. Just some of the thing you look for in nutrition. Here is a chart that show the comparison of corn to other common used feed grains.
*Note the TDN, corn has more Total Digestible Nutrients than barley, oats, wheat, and sorghum. You can also note that corn has more energy and less fiber than barley, oats, wheat, and sorghum.

*Note the TDN, corn has more Total Digestible Nutrients than barley, oats, wheat, and sorghum. You can also note that corn has more energy and less fiber than barley, oats, wheat, and sorghum.
TDN = Total Digestible Nutrients
NEm = Net Energy of Maintenance
NEg = Net Energy of Gain
CP = Crude Protein
NDF = Neutral Detergent Fiber
ADF = Acid Detergent Fiber
