Cobalt deficiency: Cobalt deficiency is one area where a high percentage of sheep farms face challenges. Issues typically start to emerge from July onwards but this can differ significantly depending on the mineral status on the farm.

Characteristic signs start with lambs performing below target and in some cases an early indicator is the skin on lamb’s ears becoming scaly or scabby, with skin flaking away. Lambs suffering from an acute deficiency can start to lose condition and start going dry in the wool despite being on a relatively good level of nutrition while tell-tale signs of more advanced problems are lambs starting to pine away.
