Taking the test

Sheep farmers in many parts of the North Island can be grateful for the foresight of sheep-breeder Colin Southey.

Thirty years ago, Colin gathered together fellow Romney and Coopworth breeders, scientists and farmers to address facial eczema (FE), a disease that not only limits production but is cruel, causing badly affected animals great distress.

Colin and fellow sheep breeders had identified that in an outbreak some animals were more badly affected than others, suggesting genetics were at play in determining tolerance to the development of full-blown FE.
