Requirement and supplementation

REQUIREMENT AND SUPPLEMENTATION

Requirement

  • Dairy cattle : 0.29 % DM
  • Pig : 0.7 % DM
  • Poultry – Broiler : 0.7 % DM
  • Poultry – Layer : 0.5 % DM

Supplementation

  • Cereal grains, fish meal and meat products are good sources of phosphorus.
  • Much of the phosphorus present in cereal grains is in the form of phytates, which are not digested and utilised in monogastrics.
  • In ruminants, hydrolysis of phytates by bacterial phytases occurs in the rumen and therefore well utilised.
