Pieter Henning is Divisional Technical Manager: Ruminants at Meadow Feeds. He holds a PhD in Animal Nutrition from the University of Pretoria. He worked since 1980 as both research scientist and applied nutritionist in the ruminant field. His areas of interest include dairy cattle, beef cattle and sheep. A career highlight was his involvement from 1990 to 2010 in the isolation, development and commercialization of Megasphaera elsdenii for use in ruminants, including high-producing dairy cows. This technology is now successfully used in South Africa and the USA. Pieter feels passionate about the role that ruminants play in our lives, and he believes that we should consciously strive for the right balance between utilizing them efficiently and treating them with respect.
