Story: Agricultural and horticultural research
The likely cause of ‘bush sickness’ was identified as cobalt deficiency in 1935 by two Western Australian scientists working with a similar problem. Trials at the Cawthron Institute in Nelson showed that if sheep suffering from the disease were dosed with a small amount of cobalt, recovery was rapid and dramatic. Both of these sheep were afflicted with bush sickness, but the one on the left has been dosed with 1 milligram of cobalt per week.
