Phosphorous

PHOSPHORUS

  • In bones and teeth
  • Roughage and forage plants

Functions

  • Mechanical strength to bones
  • Electrolytes in body fluid
  • Component of nucleic acids , phospholipids , protein , enzymes
  • Acid -base balance
  • Metabolic energy transfer , protein synthesis
  • Carbhohydrate metabolism

Deficiency of phosphorus

  • Causes
    • Soil deficient in phosphorus
    • Plants with ↓ P
  • Aphosphorosis - Endemic in certain part of world
    • Cattle
      • Poor growth & development
      • Lameness,
      • Bone diseases
      • Reproductive disorders
      • ‘’PICA’’
      • Dairy cows - ↓ milk yield
      • Rickets, Osteomalacia
  • Lamsiekte
    • Certain areas in south Africa
    • Soil deficient in P
    • Lameness , depraved appetite
    • Chew bones of dead animals
    • Infection with Closteridium botulinum leading to death
Excess of phosphorus
  • Primary
    • ↑ P in diet → Ca withdrawal from bones
    • Causes osteoporosis
    • Caused by concentrate feeding - cotton seed meal
    • Horses fed with bran diet causes MILLER’S DISEASE OR BRAN’S DISEASE
  • Secondary
    • Diseases of kidneys
    • ↑ Retension of P
    • Hypocalcemia - withdrawal from bones
