Phosphorus (P) bioavailability from different sources i.e. Dicalcium phosphate (DCP), monosodium phosphate (SP) and Diammonium phosphate (DAP) using adult rats was determined in the present study. Relative bioavailability (RBV) and phosphorus retention using three balanced diets (T1, T2 and T3) were estimated. Initial phosphorus content in rat carcass was 0.912 g. While, the final phosphorus content in all the three groups i.e. T1, T2 and T3 were 1.65, 1.85 and 1.66 g, respectively. Feed efficiency in all the three groups was numerically very close i.e. 0.3, 0.3 and 0.33 in T1, T2 and T3, respectively. Net phosphorus retained in the body of rats during the period of 30 days was 0.744, 0.934 and 0.745 g in T1, T2 and T3 group, respectively. And thus finally relative bioavailability was calculated using initial and final P content which were 93.93% for dicalcium phosphate, 96.88% for monosodium phosphate and 87.03% for diammonium phosphate.
