Hy-D® – strength to succeed

Hy-D®, our specific vitamin D3 metabolite, provides animals with a fast track to a strong skeleton and better performance. For our customers, this means a fast track to higher returns.

All animals need a strong skeleton, which is important for longevity, production, welfare and product quality. Hy-D® delivers stronger skeletons effectively.

Vitamin D3 is essential for developing robust bones. It regulates the absorption of calcium and phosphorus, which both play a critical role in bone calcification.

The difference

When vitamin D3 is fed in the diet, it has to go through two changes before it reaches the form that can be utilized by the animal. This process reduces the effective amount of vitamin D3 available to the animal and is time-consuming.

Feeding Hy-D® allows the first of these stages to be bypassed. The result is more efficient and faster uptake of the required metabolite 25OHD3, meaning stronger skeletons and healthier, more productive animals.

Hy-D® delivers significant benefits in poultry and swine production, which cannot be achieved by feeding D3 alone.


Hy-D® is supplied as a spray-dried beadlet using DSM’s patented technology. This gives a more uniform, better-flowing product with outstanding mixing properties. It is stable when included in premixes and pelleted feeds under standard conditions up to 90°C.
