Dr Enoch Bergman
Dr Enoch Bergman has been practicing veterinary medicine in Esperance for 15 years at Swans Veterinary Services. Esperance is renowned as one of the last agricultural areas within Australia to be opened up for farming as most of the region was significantly depleted in a wide range of minerals. Since moving to the area, Enoch has sampled thousands of local animals for hundreds of clients attempting to benchmark their animal's micro mineral status, to allow targeted supplementation. As would be expected, deficiencies of copper, cobalt, and/or selenium are exceptionally common within his practice area. Enoch is passionate about improving the profitability of his clients. Appropriate and timely micro mineral supplementation is a key production driver for his producers. He sees first-hand some of the benefits that Multimin is delivering and is keen to work as a mentor to further document the value Multimin can deliver to Australian beef, sheep, and dairy producers.
