The Soybean Saga: A Tale of Overproduction and Cattle Feed
Have you ever stopped to think about where your food comes from? If you eat meat, there’s a good chance that soybeans play a big part in your diet - and not in the way you might think.
The Rise of the Soybean
First off, let’s talk numbers. According to Our World in Data, global soy production has skyrocketed over the past 50 years, increasing more than tenfold. That’s a whole lot of beans! But here’s the twist: most of these soybeans don’t end up in tofu or soy milk. Instead, a whopping three-quarters of them are used as livestock feed. That’s right, the majority of the world’s soybeans are being grown to feed animals, not people.
The Environmental Impact
Now, you might be thinking: “So what? If soybeans are a good source of food for livestock, isn’t that a good thing?” Well, not exactly. You see, this massive increase in soy production has some pretty serious environmental consequences.
According to TABLE Debates, the growth in soy production has been a major contributor to deforestation, particularly in the Amazon Rainforest. This is a huge problem, as deforestation not only destroys the habitats of countless species, but also contributes to climate change.
Soybeans and Cattle Feed
So why are we using soybeans to feed livestock? Well, as it turns out, soybeans are a pretty efficient source of protein for cattle. As the Golden Plains Area Extension explains, whole soybeans can be used effectively to supply protein in beef cattle rations.
However, feeding soybeans to cattle isn’t as simple as it might seem. The Soy Meal Info Centre provides guidelines on feeding raw soybeans to cattle, indicating that there are specific methods and precautions that need to be taken.For example, one of the risks is that raw soybeans contain urease, which breaks down urea into ammonia. Feeding any combination of urea-containing products with whole raw soybeans can result in a more rapid breakdown of urea into ammonia within the rumen, potentially leading to ammonia toxicity and cattle death.
The Soy Paradox
Here’s where things get really interesting. Despite the fact that soybeans are a great source of protein, the majority of them aren’t being used to feed people directly. Instead, as a post on Biology Stack Exchange points out, more than three-quarters (77%) of global soy is used as feed for livestock, primarily for meat and dairy production.
This raises some serious questions about the efficiency and sustainability of our current food systems. If we’re growing all these soybeans, wouldn’t it make more sense to use them to feed people directly, rather than using them as an intermediary step in meat production?
As for alternatives to soybeans for cattle feed, there are several options. These include corn gluten meal or feed, distiller’s grains, brewers’ grains, and soybean hulls (a biproduct of soybean farming). Each of these alternatives has its own benefits and drawbacks, and the choice often depends on factors such as cost, availability, and nutritional needs of the cattle.
Conclusion
The overproduction of soybeans for use as cattle feed is a complex issue with far-reaching implications. It’s clear that our current food systems need to be re-evaluated and redesigned to be more sustainable and less damaging to our environment.
As consumers, we can play a part in this process by being more conscious of our dietary choices and their impact on the world around us. After all, every meal is a chance to vote with our forks for the kind of world we want to live in.

An interesting read! I'll admit that I was a little worried when I saw the title since vegetarians and vegans often come under fire for eating things like soya, almonds, avocados etc. As you go on to point out, most of the soya produced is too feed animals. Imagine if we skipped the animal and just ate the soya! A good read.
