Extract

It has long been known that a large part of organic phosphorus of cereals which are the principal constituents of concentrate mixtures usually fed to ruminants occurs in the form of phytic acid (inositolhexaphosphoric acid) or phytin (salt of phytic acid). It is also well known that in ruminants hydrolysis of dietary phytate occurs by action of phytase produced by rumen microorganisms, which renders phosphorus completely available for these animals. However some authors found that availability of phosphorus in phytate may be affected by other dietary constituents or by some features of the diet. The aim of this study was to study assimilation of phytate by ruminants and to ascertain if this form of phosphorus can be used as a good source of this mineral for ruminants.
