Dr Joe McGrath



0061 419 173 115

Dr. McGrath’s experience and credentials underscore the Sollus commitment to delivering farmers trace element and supplement products based on good science and evidence. 

His experience stretches from researching and lecturing on animal health and nutrition at Australia’s University of New England, to farm-side experience as nutrition manager at Rangers Valley cattle station. 

While at the University of New England Joe researched the mineral-vitamin interactions in grass based dairy and beef systems. Much of the science he studied there has been applied to the Sollus nutrition and mineral products now available in New Zealand. 

Eight years spent at Rangers Valley meant Joe was heavily involved in developing nutritional programmes for 50,000 head of cattle Today Joe covers much of the Pacific region advising a wide range of ruminant farmers on how best to optimise their feed inputs and maximise animal health, welfare and productivity. 

His experience both in nutritional research and hands on feed operations mean he is well placed to offer farmers practical, affordable and realistic advice on addressing their production issues.
