Given that most people feed grain primarily to keep or add weight to their critters, knowing how many calories each pound of feed contained would be really handy, especially when one was trying to compare feeds....even those made by the same company....on an apples to apples basis. Unfortunately, companies are not required to place this information on feed tags so nobody does. It's been my experience that some companies are a lot more forthcoming with this sort of information than others are, but they will usually provide it to you if you call or email a request to them.
Sometimes, getting the numbers you need and comparing feeds based on energy levels leads to some interesting and counter intuitive results. I once had a case where Feed A and Feed B had nearly identical tag specs (which don't tell how much energy each feed might contain) but had markedly different prices. Of course, all things being equal, everyone went for the cheaper option which in this case was Feed B. However, the energy content of Feed B was so much lower than Feed A that Feed A actually worked out to be considerably cheaper to feed if one took the time to find out how much energy each feed contained. To strengthen this important point, let me highlight this with a hypothetical example.
Feed Required to Achieve 10,000 kcal from grain
Feed X - Price $ 12.00 per 50 lb bag - DE 1500 kcal/lb - 6.67 lbs - Cost - $ 1.44 per horse
Feed Y - Price $ 10.00 per 50 lb bag - DE 1000 kcal/lb - 10.0 lbs - Cost - $ 2.00 per horse
