Oats 11-14%
Corn approximately 10%
Out of the common feed stuffs in the USA, corn has the highest Mcal value. The problem with corn is it is lower in protein, especially the necessary amino acid LYSINE. So It is important to add a protein supplement if feeding corn to horses. Always remember to do any dietary changes gradually to avoid colic and founder.
Sweet corn is way higher in protein than regular corn.
Protein average in corn silage is 6-9%.
It takes a lot more energy, water, labour to produce a pound of meat than a pound of corn. It takes pounds of corn and water to feed just one pig.
Beef has more protein
For our discussion, the two most important factors affecting corn's BTUs is moisture content and test weight. Moisture content subtracts directly from the overall weight of the corn. For example, if you have a pound of corn at 13% moisture, subtract .13 from the pound, which therefore equals .87 pounds of zero percent moisture corn. 13% of a 40-pound bag gives the consumer 34.8 pounds of zero percent moisture corn. Therefore it is evident that moisture is a key component in the amount of BTU's corn delivers. The other variable as we have stated above is test weight. Test weight is the measure of the quality and the number of BTU's per pound. Seed corn, cultivation, and weather determine the test weight per bushel. Higher test weights yield a larger BTU per pound. Typically test weight can range from 50 to 58 pounds per bushel, which corresponds to 7600 to 8500 BTU's per pound of zero percent moisture corn. When taking into consideration moisture and test weight we can fairly estimate the BTU's per pound and bag. The average test weight this year was 57.1 pounds per bushel, which equates to approx. 8,410 BTU's per pound at zero percent moisture. At 13% you have .87 pounds of zero percent moisture corn, which equals 7,316 BTU's per pound, because of the moisture content there is a loss of 1,094 BTU's per pound. Therefore, the total energy per bag would be, 40 pounds at 13% moisture times 7,316 or 292,640 BTU's per bag. When comparing with LP, 3 gallons of LP equals 274,500 BTU's. The average cost of LP has been 1.80 per gallon or 5.40 for three gallons. Therefore a 40-pound bag of corn will yield 18,140 more BTU's than 3 gallons of LP. The exact number of BTUs per pound of corn must take in efficiency of your stove, furnace or boiler.
Stalks do have protein, but very little compared to the amount of protein that is found in the corn kernels. The amount of protein in a corn stalk is considered irrelevent in comparison to what is found in the kernels.
