PHYTEX 500
FORMULATION GUIDE

GUIDE FOR USE AND FORMULATION OF PHYTEX 500:

The use of PHYTEX 500 saves in protein and phosphorous values in the formula. Thus, the following basic corrective adjustments downward in feed, must be made:

  • Proteins 1.50 %
  • Energy 3.25 %
  • Phosphorous 0.10 %

Increase in phosphorous digestibility due to phytase in PHYTEX 500:

  • Standard reference of digestibility, %: 0.495 (digestible phosphorous liberated in rati๓n of 0.44 % of phosphorous).
  • Digestibility for uniform dosis of PHYTEX 500, %: 0.630
  • Increase in phosphorous digestibility , %: 0.135
  • Digestible liberated phosphorous, %: 0.0594 calculated as follows: (0.630-0.495)*0.44
  • Digestible liberated phosphorous, gr/kg: 0.594 gr/kg.
  • Bioavailable inorganic phosphorous replaced by phytase ( defluorinated phosphate.), %: 0.100
