bush sickness
LowSpecialized / Technical / Historical
Definition
Meaning
A disease of livestock, especially cattle and sheep, caused by a deficiency of cobalt in the diet, leading to anemia, wasting, and poor growth.
In historical and agricultural contexts, it refers specifically to a wasting disease affecting animals in cobalt-deficient regions like New Zealand and Australia. No significant extended figurative meaning exists.
Linguistics
Semantic Notes
This is a historical agricultural term. Modern veterinary science more precisely refers to 'cobalt deficiency' or 'enzootic marasmus'.
Dialectal Variation
British vs American Usage
Differences
The term is strongly associated with former British Empire pastoral regions, particularly New Zealand and Australia. In US agricultural contexts, the condition is not typically referred to as 'bush sickness'.
Connotations
Primarily technical and historical. Carries strong regional connotations of Australasian farming history and soil science.
Frequency
Extremely rare in everyday language in both the UK and US. Its use is almost exclusively confined to historical texts or specialist agricultural/veterinary discussions, primarily in a New Zealand or Australian context.

Common Mistakes
- Using it as a general term for any animal sickness in wilderness areas.
- Spelling as 'bushsickness' (should be two words or hyphenated: 'bush-sickness').
