Abstract
The phosphorus (P) in vegetable sources is bound as phytate P, and as such the degree of availability depends on phytase activity naturally found in feed ingredients (Pointillart et al. 1987). The amounts of P available to pigs from feeds of plant origin are usually insufficient to obtain high levels of performance and pig diets are often supplemented with inorganic P (Jongbloed et al. 1991). However, the P component of piggery effluent is an environmental concern and therefore the continued supplementation of pig diets with inorganic P is clearly not an acceptable practice for sustainable agriculture. The hypothesis for this experiment was that the supply of available P could be maintained in low-P diets by supplementation with biologically active forms of the phytase enzyme.
