Corn is the most energy efficient crop - All About Feed (2024)

Corn, sugarcane, switchgrass, all can be used to make ethanol. But what is their real value? Dave Vander Griend of ICM concludes that corn gives the best value for money.

As productivity on the farm and in the ethanol plants increases, it is critical to understand the net impact of corn ethanol on the corn supply.

One of the frustrations for the corn ethanol industry in the whole indirect land use/lifecycle analysis debate is that the value of co-products such as distillers grains (DDGs) are often ignored.

Dave Vander Griend, president and CEO of ICM Inc, has just released a white paperon the subject, “Rethinking the value of corn ethanol co-products in lifecycle assessments.”

ICM is a Kansas-based company that has been building and designing ethanol plants since 1995, with a special emphasis on improved process design and energy efficiency.

Co-products underrated

According to Vander Griend the value of ethanol co-products is highly underrated. “Recognition of the co-products that come from ethanol production is absolutely fundamental to understanding the true value of corn as a food and energy crop,” he says.

Ethanol production returns about one third of the corn it utilizes in the form of DDGs for livestock feed. The nutritional value of that feed is actually 50% better than raw corn.

When harvesting a hectare of corn for ethanol production only half of the equivalent of that hectare is used to make ethanol. The other half is returned in nutritional value to feed livestock for the human food supply.

“This feed credit should be calculated when determining the overall demand for corn for ethanol production and the ultimate lifecycle analysis for ethanol,” Vander Griend says.

In a comparison between corn, switchgrass and sugarcane as feedstock for ethanol production, Vander Griend concludes: “All three of them will give you fuel, but when you look at which ones will give you food and fuel, you only have corn.”

He says if you count the food and feed value of corn utilized for ethanol, corn is actually the most efficient energy crop.

FAQs

Is corn the most efficient crop? ›

Corn, sugarcane, switchgrass, all can be used to make ethanol.

Is corn energy efficient? ›

Production of corn-ethanol is energy efficient, in that it yields 34 percent more energy than it takes to produce it, including growing the corn, harvesting it, transporting it, and distilling it into ethanol.

Why is corn used as animal feed? ›

In addition to improving growth efficiency, corn grain is fed to cattle in the finishing phase because it increases carcass quality grades by increasing fat deposition (especially intramuscular or “taste” fat), which results in a more desirable product for consumers.

What percent of corn is fed to animals? ›

Corn is a major component of livestock feed. Feed use, a derived demand, is closely related to the number of animals (cattle, hogs, and poultry) that are fed corn and typically accounts for about 40 percent of total domestic corn use.

Is corn the most widely used energy feed? ›

Corn is the most widely produced feed grain in the United States, accounting for more than 95 percent of total feed grain production and use. The other three major feed grains are sorghum, barley, and oats. Most of the corn crop provides the main energy ingredient in livestock feed.

Why is corn an important crop? ›

In a literal sense, corn contributes 10% of the fuel for all cars in the US. That ethanol accounts for more than forty percent of all the corn produced. Much of the remaining sixty percent of the corn produced goes to livestock feed: it is fuel for the animals that feed the citizens.

Is corn an energy crop? ›

Energy crops, such as corn and sugarcane, are one of the main sources of biomass-based feedstocks that have been examined for biofuel production.

What is the most energy efficient food? ›

Certain foods require less energy to produce than others, whether because it requires less land and water or because there are fewer industrial processes needed to produce it. The most energy efficient foods include wheat, beans, fish, eggs, nuts and other non-resource-intensive products.

Does corn give you energy? ›

Dietary fiber: Corn contains dietary fiber, which aids in digestion, promotes satiety and helps maintain bowel regularity. Antioxidants: Corn contains certain antioxidants, such as lutein and zeaxanthin, which are beneficial for eye health. Energy: Corn is a carbohydrate-rich food, that provides energy for the body.

What animals eat feed corn? ›

What wild animals are attracted to the corn? While it may vary based on where you live and the time of year, you can catch many animals around your home by using corn, including: songbirds, hawks, crows, quail, squirrels, opossum, rabbits, raccoon, foxes, turkey and deer.

Why is corn used instead of grass to feed cows? ›

Not only does corn provide valuable nutrition, but it also helps keep the cost of raising cattle and buying beef at the store more affordable. It takes significantly longer for a steer or heifer to reach market weight if it only eats grass and is never fed corn—which is called grass-finished beef.

Will cows eat corn? ›

Cows can be fed whole corn as a supplement. Corn would be considered an energy feed and therefore an energy supplement. In high forage cow diets, I would not feed more than 3 to 4 lb per head per day.

Who eats the most corn? ›

Corn Consumption Per Person

By a wide margin, the most significant consumers of corn per person are Mexico, followed by South Africa. Mexico makes perfect sense here, as Mexican street corn is one of the world's most iconic dishes -- and Mexico is where corn was first domesticated.

What human foods can cows not eat? ›

Kale, rape, turnips can cause hemolytic anemia in cows if that is the basis of their diet. Symptoms include weakness, brown or red urine, collapsing, and death. Brassicas may absorb enough amounts of nitrites that can result in nitrate poisoning in large enough amounts.

What is the number one food crop in the world? ›

According to the United Nations Food and Agriculture Organization (FAO), sugarcane, maize, rice, and wheat are the most consumed crops in the world.

What is the world's most productive crop? ›

Aside from sugar cane in first place, the next the top three most produced crops in the world are all classified as grains. Grains include cereals and legumes and are such a widespread crop because they can grow in almost any climate.

What is the most space efficient crop? ›

Calorie farming produces a complete diet in the smallest space possible by focusing on special root crops that are calorie-dense and yield well in a small area. These specific crops are: potatoes, sweet potatoes, parsnips, leeks, garlic, Jerusalem artichoke, and salsify.

What is the most profitable crop to grow? ›

Dubbed "red gold", saffron's high market value makes it arguably the most profitable agricultural crop. Though it requires careful cultivation, the potential profits per acre are unmatched, highlighting its viability for small farms looking to maximize their earnings.

Is corn the most consumed crop? ›

According to the United Nations Food and Agriculture Organization (FAO), sugarcane, maize, rice, and wheat are the most consumed crops in the world.
