MSD Animal Health has always been a research driven company and is proud to have the only South African company-owned research unit in South Africa. This fully accredited Research Unit, based in Malelane, is responsible for both local and international research and development. The Malelane Research Unit is situated in the beautiful Kaalrug Valley of the Mpumalanga Lowveld, 26 km from the southern border of the famous Kruger National Park. The main activities taking place at the research unit are the development and testing of new ecto and endoparasitic drugs. The pastures are naturally infested with ticks and the resident cattle herd is the ideal model for testing the activity and safety of these drugs. Ticks are tested for resistance to the various ectoparasiticides, farmers are advised.
