Study Notes
- General clinical signs of trace element deficiency include wasting/poor growth rate, poor reproductive performance, and poor neonatal vigor.
- Copper functions as a cofactor for metalloenzymes, aids in collagen crosslinking, myelin production, iron absorption, and melanin production.
- Copper deficiency clinical signs include poor coat quality, poor growth/anaemia in cows, swayback in lambs, and infertility/poorly pigmented coat/water diarrhea in cows.
- Testing for copper deficiency can be done by evaluating plasma copper levels or whole blood, with tissue level measurement being more sensitive.
- Treatments for copper deficiency include drenching, injections (lasting 2-4 months), and boluses (which may contain other trace elements).
