Towards medication-free animal production!


Nor-Add, Nor-Feed A/S, and its sister-company Dumas ApS, develop, manufacture and market highly efficient natural additives for inclusion in animals’ feeds and drinking water internationally.


The natural additives are based on highly efficient polyphenols and saponins that

  • stimulate feed intake by improving feed palatability – this can lead to improved daily weight gain
  • improve the animals’ health and productivity
  • reduce animal stress
  • improve the output quality of animal production


Nor-Add, Nor-Feed A/S’ natural additives are safe for humans to work with, safe for the animals receiving them, and safe for the environment. The additives provide cost-efficient alternatives to many traditional growth promoters and heavy metals that are known to have undesirable side-effects like the development of antibiotic resistance.

Nor-Add, Nor-Feed A/S co-operates with veterinarians, feed-manufacturers and livestock-producers, as well as with universities and other research institutions, to ensure that customers are guaranteed a range of products that are innovative and offer well-documented benefits.

In order to ensure that every batch of the company’s products is of consistent high quality, all products are quality-controlled by external laboratories in West-European countries.
