Summary and Implications
The digestibiltiy of P in dicalcium phosphate, a P source considered to have a high relative bioavailability , was determined to be 68.1 % in pigs. The digestibility of the phosphorus was not altered by dietary calcium/available P ratio or stage of pig growth (10 vs 30 kg body weight).These data highlight the opportunity/incentive for technologies aimed at improving P digestibility in P sources (inorganic P sources) with high relative phosphorus bioavailabilities.
