When we add  milk into our coffee or tea, or grab a block of cheese at the supermarket, we don’t really think about what cows eat to make it all possible. But behind every bowl of yogurt or splash of milk lies a carefully planned cow diet—and one  ingredient that has gotten a lot of attention is palm kernel.

Yes, palm kernel. And no, it’s not some fancy health food—it’s actually a byproduct of palm oil production. But don’t let that fool you. For dairy farmers, it can be  a great help in certain periods of the year.

What Exactly Is Palm Kernel?

Palm kernel (often referred to as palm kernel expeller or palm kernel meal) comes from the inner part of the palm fruit, after the oil has been extracted. What’s left is a dry, fibrous material—rich in energy and fiber—that’s surprisingly good for cows.

Why Do Cows Need Special Feed?

Cows don’t just eat grass all day—especially if they’re producing lots of milk. High-producing dairy cows need extra energy, kind of like athletes. And during certain times of the year, fresh pasture alone just doesn’t cut it.

That’s where supplements like palm kernel come in.

How Palm Kernel Helps With Milk Production

Here’s the simple version: palm kernel is high in digestible fiber and provides a slow, steady release of energy. This makes it easier for cows to keep up with the demands of making milk—especially when pasture is poor or when there is not enough pasture or when they’re under stress (like during calving season).

In practical terms:

•  Cows stay healthier.
  
•  Milk volume can go up.
  
• Farmers can spend less on more expensive grains.
  

Is It Natural?

It’s not synthetic, but it is a processed byproduct. Still, many farmers appreciate that it comes from the waste stream of palm oil production—so using it actually reduces waste.

Of course, ethical sourcing and sustainable farming practices are key, and many countries (like New Zealand) are mindful of how and where palm kernel is imported from.

Any Downsides?

Like any feed, it has to be used in balance. Too much palm kernel and cows might not get enough protein or other nutrients. It’s like living off granola bars—great for energy, but not a complete diet.

That’s why farmers often mix it with grass, silage, or other grains to keep things balanced.

 A Tool, Not a Miracle

Palm kernel doesn’t work magic—but it’s a useful tool. Think of it like fuel: if you want high performance, the right fuel makes all the difference.

For farmers, especially during dry seasons or times of low pasture growth, palm kernel helps keep the milk flowing, the cows strong, and the business sustainable.

So, Next Time You Enjoy Cheese…

…just remember: there’s more behind your dairy products than you might think. Palm kernel might not sound exciting, but it’s one of the many things farmers use to bring milk from the paddock to your plate.

And that’s pretty cool, isn’t it?
