Effects of level of supplemental phytase on ileal digestibility of amino acids, calcium, and phosphorus in dehulled soybean meal for growing pigs

Traylor, S.L., Cromwell, G.L., Lindemann, M.D. and Knabe, D.A. 2001. Effects of level of supplemental phytase on ileal digestibility of amino acids, calcium, and phosphorus in dehulled soybean meal for growing pigs. J. Anim. Sci. 79:2634-2642. Link to full text (.pdf)

 

Take-home message:

  • Apparent and true ileal digestibility of P increased quadratically (P < 0.01) and true digestibility of Ca increased linearly (P < 0.07) with increasing levels of phytase.
  • Effects of phytase on digestibility of amino acids is unclear.
