Young Animal Feed


CALCOLIN is one of the safest raw materials in the feed industry. CALCOLIN’s starting material consists of fresh shells of eggs (Gallus gallus domesticus).

The risk of unwanted micro-organisms is present and recognized in the further processing. Therefore all eggshells undergo a standard heat treatment to be used for animal feed. The applied heat treatment results in a substantially sterile product having such a low Aw-value, that regrowth of micro-organisms can be ruled out.


A number of studies show that the calcium availability and
digestibility of CALCOLIN is much (40%) higher than that of
limestone or coral sources.

CALCOLIN has an extremely low iron content (especially suitable for lean meat production).

CALCOLIN shows better egg quality, calcium utilization and laying percentage.

CALCOLIN has a substantially lower buffer capacity compared to fine ground limestone. This is important weaning piglets face difficulties keeping the stomach sufficiently acidic.


The awareness is growing that we have to use valuable nutrients that nature offers us in the most efficient way possible. Annually several billions of eggs are broken in the Netherlands serving the egg industry.

This results in a significant flow of eggshells and valuable recyclable nutrients which form the basis of the CALCOLIN: a therefore completely renewable source of calcium.

This way, every year large quantities of calcium go back into the food chain (circular economy) and significant amounts of limestone can remain in the earth.
