Copper
- Activity
- Prosthetic group -
enzyme activator.
Enzyme will not function
without it
- Haemoglobin synthesis
- Cu part of the enzyme Ceruloplasmin which
facilitates release of Fe from Ferritin in the liver
- Fe is used in the spleen and
bone marow to form
Haemoglobin
- Fe is used in the spleen and
bone marow to form
Haemoglobin
- Haemoglobin deficency
results from 1) Fe
deficency 2) Cu deficency
3) Co deficency
- Cu part of the enzyme Ceruloplasmin which
facilitates release of Fe from Ferritin in the liver
- Bone Growth
- Controlled by Osteotypes
- Cu needed so that
osteoblast (build bone)
activity occurs
- Deficient - reduced
mineralisation result in
fractures
- Controlled by Osteotypes
- Nervous System
- Cu responsible for an
enzyme which
maintains the myelin
sheath.
- If not maintained,
cross firing occurs
e.g. discoordination
and swayback in
lambs.
- Cu responsible for an
enzyme which
maintains the myelin
sheath.
- Cardiovascular system
- Cu need by the enzyme responsible for elastin
formation
- Need elasticity to prevent sudden aortic
ruptures as blood pressure buids
- Deficient - Falling disease in Cattle
- Need elasticity to prevent sudden aortic
ruptures as blood pressure buids
- Cu need by the enzyme responsible for elastin
formation
- Melanin Synthesis
- Enzyme dependent on Cu to
regulate melanin activity
- Deficiency = de-pigmentation around the eyes 'spectral
appearance' or loss of wool crimp as disulfide bonds break
- Enzyme dependent on Cu to
regulate melanin activity
- Prosthetic group -
enzyme activator.

- Requirements
- Dairy Cows 10mg/kg DM
- Beef & Sheep 5mg/kg DM
- Dairy Cows 10mg/kg DM
- Supply
- Forage 6-12mg/kg DM
- Cereals 4-10mg/kg DM
- Oilseeds 10-30mg/kg DM
- Forage 6-12mg/kg DM
- Calcareous soils (Teart Pastures)
- Molybdenum (Mo) present in these soils (20-100mg/kg DM) as is Sulphur
- S and Mo lock up Cu in Copper thiomolybdate
- Mo + S + Cu ------> CuMoS4
- S and Mo lock up Cu in Copper thiomolybdate
- Fe will also lock up Cu
- Molybdenum (Mo) present in these soils (20-100mg/kg DM) as is Sulphur
- Toxicity
- Pigs tolerate high [Cu] and can promote growth
- Sheep not tolerant so will not be
included in free access mineral
block.
- Cattle can have mineral blocks with it in.
- Pigs tolerate high [Cu] and can promote growth
- Treatment
- Inject CuSO4 or provide in a bullet which lodges in the
reticulum and release a controlled amount over a period of
time.
