Published:November 21, 2007
Summary
IMPORTANCE AND PREVIOUS WORK Less than one-third of the phosphorus (P) contained in feed ingredients of plant origin is biologically available to monogastric animals (NRC, 1994). The remainder of the phosphorus is tied up as phytate (phytic acid or myoinositol hexaphosphate) and monogastrics as a general rule lack the enzyme(s) necessary to hydrolyze phytate down to phosphorus and inositol (Pe...
