In 1995 Avimune (Pty) Ltd was incorporated, under the leadership of Dr Hannes Swart, as a management buy-out of the Golden Lay Laboratory and experimental facilities. He served as Managing Director of Avimune from 1995 until 2005. With new and extending possibilities in the animal health industry the scope of the business extended beyond poultry and the original Avimune laboratory was restructured into Deltamune, an ISO 17025 accredited laboratory and vaccine manufacturer in 2005. Dr. Hannes Swart was the CEO of Deltamune from 2005 to 2014 and is currently a Director of Avimune.

Prior to his work with Avimune, Dr Swart worked as Production Manager: Health and Biological Services for Golden Lay Farms for 7 years and before that for two years at the Onderstepoort Veterinary Institute (OVI), primarily responsible for Rabies diagnostics.

Dr Swart obtained his BVSc in 1987 and completed the course work for the MMedVet in Poultry Health in 1995 as well as an MDP at the UNISA School of Business Leadership in 1994.
