We strive to add meaningful value within all aspects of animal production with specialized attention in intensive beef, dairy and sheep production.

After completing his BSc Agric degree, Henning worked as a farm manager and in 1999 joined OTK Feed Company working in dairy and beef technical management as well as in the development of molasses based liquid feed supplements.

Henning founded Essential Nutrients Systems in June 2001. Initially the company only focused on providing nutritional technical support and management systems for feedlot and dairy industries.
