6. What is Achromotrichia?
- Copper deficiency causes depigmentation of hairs and wools known as achromotrichia.
7. Spactacle disease occur due to deficiency of which mineral?
- Copper.
8. How copper deficiency occur?
- It occurs due to,
a. Grazing in copper deficient soil &
b. Secondary deficiency occur due to high level of molybdenum.
9. How anaemia occrs due to copper deficiency?
- Low level of copper causes hindrance in the process of haematopoieses resulting into anaemia.
10. Which type of anaemia is caused by iron deficiency?

- Oxidative damage.
15. Define “Sway Back”
- Copper deficiency produce demylination of CNS. There is a necrosis and neuronal degeneration of spinal cord and brain stem, such animal show nervous manifestation known as Sway back or neonatal ataxia.
