Copper
Source
Functions
- Controls absorption of iron from intestine
- Haemoglobin synthesis
- Component of cytochrome oxidase
- Phospholipid synthesis
- Activates oxidase, tyrosinase, succinic oxidase
DEFICIENCY DISEASES
Causes
Piglets
- Haemopoetic tissues - Microcytic Hypochromic anemia
- Baby pigs raised on wooden or concrete floors
- Deprived of soil
- Anemia
- Sow’s milk → ↓ Cu→ Deficiency
Sheep
- “Steely wool”
- Wool becomes more hair like
- Loses its color due to decreased melanin
Disorders of CNS
- England and Australia - sheep and goats
- “Enzootic ataxia or SWAY BACK”
- Sheep grazed or molybedenum rich grasses (Mo antognostic to Cu)
- Incoordination, weakness of hind legs
- Spastic paralysis, blindness
- Demyelinization, softening and necrosis of cerebrum
Cattle
“Falling disease”
- Australia and USA
- Cows falls and die suddenly
- Anemia / Loss of weight /Diarrhoea
- Fibrosis of myocardium
- Degeneration of elastic tissue
Skeletal system
- Depression of osteoblastic activity
- Osteoid is not deposited in cartilage
- Osteoporosis - Cattle
- Swelling of long bones especially above pastern region
- Fracture of ribs, femur, humerus
- Infertility, retained placenta, rickets in calves
Excess of copper
- Drenching sheep with CuSo4 for stomach worms causes gastritis, enteritis, death
- Poultry – Poisoning - depression , convulsions , coma
- Humans –Wilson’s disease
