How Much Grain Does It Take to Produce 1 Kg of Beef?

Post date |

Meat Free Monday is all about eating less meat because it’s better for your health and the environment.

The Food and Agriculture Organization (FAO) says that the livestock sector will have to produce 463 million metric tons by 2050, up from 228 million metric tons in 2010. This is to meet the growing demand. In this case, the number of cattle would increase from 1. 5 billion to 2. 6 billion and goats and sheep from 1. 7 billion to 2. 7 billion. (FAO).

There is more than enough food produced to feed everyone on Earth, but more than 690 million people still go hungry. Something that could help is if the land that is used to raise animals or grow crops for animals could be used to grow food for people instead! 26% of the world’s ice-free land is used for livestock grazing, and 33% of croplands are used to grow crops for livestock. Every kg of beef needs 7 kg of grain, and every kg of pork needs 4 kg of grain (White, T 2000). Estimates vary but a “typical” meat eater’s diet needs 2. 5 times more land than a vegetarian’s (Nonhebel, S 2004). A diet of cereals, fruits, vegetables, and vegetable fats can feed up to thirty people on a hectare of land. On the other hand, meat and dairy production on the same hectare of land would only feed five to ten people (Pachauri, R). K 2008). There would be a huge difference if soy beans were used to feed people instead of animals. However, some people don’t like the taste of soy beans. A study by Tickell (1991) found that 10 hectares (or 5 football fields) of soya could feed 61 people. On the other hand, the same area of land could feed 10 people on a maize-based diet or 24 people on a wheat-based diet. The same area of land used to raise animals would support only 2 people.

Some land isn’t good for growing crops, so letting animals graze on it is a good use of that land. In the UK, groups like the National Trust often use grazing animals to keep grasslands and other habitats in good shape. However, as meat production increases, more and more wild habitats are lost and intensive farming tends to increase.

Raising cattle for beef is an extremely grain-intensive process. Vast amounts of edible crops like corn, wheat, and soybeans are fed to cows as they are fattened up for slaughter But just how much grain goes into producing a kilogram of beef? The answer may surprise you

On average, it takes 25 kg of grain to produce just 1 kg of feedlot-finished beef

This startlingly high grain-to-beef ratio illustrates the inherent inefficiency of cycling crops through livestock to produce meat. Huge proportions of calories protein and other nutrients are wasted by feeding grain to cattle rather than consuming it directly.

Below we’ll look at the key factors determining this 25:1 feed to meat ratio, what the numbers mean for food security and the environment, and how grass-fed beef compares.

Why So Much Grain for Beef?

Several key reasons explain why it takes so many kilograms of grain to produce just one kilogram of feedlot beef:

  • Cows are ruminants – With a four-chambered stomach optimized for digesting grasses, cattle are poorly adapted to grain-based diets. They convert grain to meat less efficiently than pigs and chickens.

  • Most weight gain is inedible – The majority of cattle’s grain-fueled growth consists of bones, fluids, organs, and other body parts we don’t eat. Only a fraction of weight gain goes toward edible muscle meat.

  • Grain displaces grass – Feedlots minimize land usage by displacing cow’s natural grass diet with dense, protein-packed grain rations. While more land-efficient, this practice trades sustainability for efficiency.

  • Cattle reach slaughter weight quickly – Modern cattle breeds fed growth-promoting hormones and rich grain diets reach slaughter weights of 400-600 kg in just 14-18 months, gaining over 2 lbs per day.

  • Larger carcass size – Over the last 40 years, cattle genetics and growth stimulants have increased the average carcass weight by over 20 percent. Bigger cattle demand more grain.

Impacts on Food Security

With over 795 million chronically undernourished people worldwide, the inefficiency of grain-fed beef represents a tragic waste of precious food resources.

  • Over 1/3 of global cereal grains like corn and wheat are fed to livestock for meat production rather than directly feeding people.

  • If just 30% of global beef production was shifted to plant-based proteins like beans and lentils, enough grain would be freed up to feed an extra 3.5 billion people.

  • An estimated 20 kg of grain could feed one person for an entire day. So 25 kg of grain produces just a single 1 kg beef steak, enough for a single serving.

Impacts on the Environment

In addition to wasting grains needed for food security, grain-fed beef production has massive environmental costs:

  • Vast tracts of wildlife habitat across North and South America have been converted to grow livestock feed grains. This is a leading cause of biodiversity loss in sensitive ecosystems.

  • Chemical fertilizers and intensive irrigation applied to grow feed crops pollute waterways and aquifers and contribute to ocean dead zones.

  • Feed production and the cattle themselves produce enormous volumes of greenhouse gases driving climate change. Beef has one of the highest carbon footprints of any food.

Grass-Fed Beef Uses Less Grain

Feeding cattle primarily on pasture grasses rather than grain reduces the grain inputs substantially. However, exclusively grass-fed beef still has sustainability issues:

  • More land is needed for grazing, necessitating deforestation for pastures.

  • Grass-fed cattle generate more methane than feedlot cattle, amplifying climate change impacts.

  • Without routine antibiotics, grass-fed cattle have higher mortality rates. More animals are needed to produce the same meat weight.

  • True 100% grass-fed beef is rare. Most marketed grass-fed beef is “finished” on grain for faster weight gain.

While less grain-intensive than feedlot beef, grass-fed beef essentially swaps one set of ecological problems for another. The inherent inefficiencies remain.

The Takeaway

With a grain-to-beef conversion ratio as high as 25:1, the resource costs and environmental impacts of grain-fed beef production are clearly immense. While grass-fed systems have advantages, ultimately beef production is extraordinarily inefficient regardless of feeding practices.

Transitioning toward more plant-based diets and protein sources is a responsible way individual consumers can help conserve global food resources, preserve ecosystems, and reduce their personal environmental footprint. With burgeoning populations and increasing climate instability, our food choices matter more than ever.

FAQ

How much grain does it take to produce beef?

In reality, it takes 2.5 pounds of grain to produce 1 pound of beef we eat in the United States. For the first six to eight months of a calf ‘s life it is primarily consuming mother’s milk with a nibble of grass and hay to stimulate their rumen development. An average calf is 600 pounds before it begins to eat grain.

How much feed to produce 1kg of beef?

Table 2 shows that the production of 1 kg of beef requires 8 kg of feed and 14.5 thousand liters of water. For 1 kg of pork, 3 kg of feed is needed and nearly 6 thousand liters of water, while salmon farming seems to be the most effective and ecological because it requires only 1.1-1.2 …

How many kilograms of grain does it take to produce one kilogram of beef?

Eat more plant-based meals Growing animals for food is also inefficient. It takes about five to seven kilograms of grain to produce one kilogram of beef. Each of those takes energy and water to produce, process and transport. As global meat consumption increases, so does its climate impact.

How much feed does it take to produce 1 lb of beef?

The pounds of feed required per pound of gain in cattle can vary depending on factors like feed efficiency and diet composition. On average, it may take around 6 to 8 pounds of feed to produce 1 pound of gain in cattle. It all depends on the period of life to which you refer, and on how you do the math.

How much grain does it take to make 1 kg of beef?

All too often people end up using numbers they don’t quite understand and this leads them to recommending policies that have only the most tenuous connections with reality. My particular ire today is over this oft quoted number that it takes 7 kg of grain to make 1 kg of beef. Given this we must all become vegetarian or poor people will die.

How much feed does it take to produce 1kg of beef?

It takes 25kg of dry feed to produce 1kg of edible beef meat. The feedlot industry has also been successful in raising more cows, more quickly, thus encouraging greater consumption of beef, which in turn poses significant environmental and human and animal health risks.

How much grain does it take to produce protein?

Because it relies upon one particular technology: The efficiency with which various animals convert grain into protein varies widely. With cattle in feedlots, it takes roughly 7 kilograms of grain to produce a 1-kilogram gain in live weight.

How much water does it take to make one pound of beef?

Recently a professor of food science at the University of Guelph commented that it takes, “more than 10 pounds of feed and 8 gallons of water to produce one pound of edible beef”.
