WebPhosphorus (P) is an inorganic element that is important for devel- opment and maintenance of the skeletal system.1Diets formulated with excess P can have a negative impact on the environment due to increased P excretion.2This fact sheet will briefly explain the dif- ferent ways that P can be expressed, how to assign a phosphorus (P) value to an … WebPhosphorus is one of the most expensive nutrients in swine diets. Use of standardized total tract digestibility (STTD) of P, instead of apparent total tract digestibility (ATTD), may reduce the cost of diets because STTD values, unlike ATTD values, are additive in mixed diets.Values for STTD of P can be determined by correcting ATTD of P for the basal …
