Colostrum: The OG milk. What is in it, and why is it so important?

Before regular milk comes in, a cow produces the first milk: colostrum, or first milk. Raw, thick, yellow, and packed with nutrition. No hype, no fuss. Just what nature has always done.

For the calf, this is literally a matter of life or death. For humans? Interesting. Provided we don't forget who it is intended for: the calf.

Why colostrum is crucial for the calf

A calf is immunologically naked

No antibodies received from the mother. No protection in the womb. The calf is completely dependent on those first sips of colostrum after birth. These contain, among others:

• Immunoglobulins (IgG, IgA, IgM): direct defense against pathogens.

• Zinc: helps the immune system function.

• Omega 3 fatty acids: anti-inflammatory and good for growth.

• Essential amino acids such as leucine, lysine, and glutamine: muscle growth, recovery, gut health.

• Vitamins A, D, B12: important for vision, immunity, energy, and bones.

Those first hours are sacred. Giving colostrum within 2 hours = greatly increased chance of survival. After 12 hours, the absorption of all those important substances drastically decreases.

But what about humans and colostrum?

Increasingly, you see bovine colostrum as a supplement: powder, capsules, shots. For the intestines, immunity, muscle recovery. Is it worth it?

Facts we can substantiate:

• Zinc helps with wound healing and immune system.

• Omega 3 supports heart and brain.

• B12 contributes to less fatigue.

• Essential amino acids help with recovery and muscle building.

And yes, colostrum also contains growth factors like IGF-1 and substances like lactoferrin. Interesting stuff. But no hard health claims have been approved yet. So we won't make a marketing party out of it.

What is often forgotten:

the calf must first dIn large-scale systems it happens too often: colostrum is harvested for the market, while the calf is left wanting. That is not our way.

Fortunately, many Dutch farmers, and specifically regenerative farmers, see it differently: the calf drinks first. For several days. Calmly. With the mother nearby. Only what remains is possibly used for people.

That's how it should be.

Real Roots take:

Colostrum is powerful nutrition. For the calf. And maybe for us too. But then:

• From a healthy system where the calf gets its share

• Without empty promises or inflated claims

• With raw honesty about what it is

Nutrition that makes sense starts with care for both animal and soil. Colostrum is a great example of that. But only in the right place in the chain.
