National audienceThe tables published by INRA-AFZ in 2004 supply several new feedstuff characteristics concerning phosphorus (P), which have been integrated in new ophosphorus unit systems for different animals, particularly for ruminants, pigs and poultry. The utilisation of such systems was studied here in the formulation of compound feeds for growing pigs by linear programming. The new system (INRA-AFZ, 2004) was compared to the previous one (INRA, 1989). Several models were proposed in order to take the action of vegetal and microbial phytases into account. First, a linear effect of microbial phytases on the liberation of digestible phosphorus was studied. Then, microbial phytasic activity was tested through a non-linear relation with a...
