The animals were divided into 6 groups having 3 animals in each to one of group and randomly allocated into six diets in a Completely Randomized Design (CRD). Six dietary treatments are : T<sub>0 </sub>(control diet), T<sub>1 </sub>(Control + DCP), T<sub>2 </sub>(Control + Bone meal), T<sub>3 </sub>(Control+ mustard oil cake), T<sub>4 </sub>(Control+ sesame oil cake) and T<sub>5 </sub>(Control + poultry litter). The controlled diet contained 0.20% P and DCP, Bone meal, mustard oil cake, sesame oil cake and poultry litter were added to diets T<sub>1</sub>, T<sub>2</sub>, T<sub>3</sub>, T<sub>4 </sub>and T<sub>5</sub>, respectively to elevate the dietary P level of 0.45% for meet up the deficiency. The lowest daily DM intake (g/d) was observed in animals fed on diet T<sub>0 </sub>and the highest value was recorded for diet T<sub>5 </sub>and significantly (P<0.05) differences were observed among the dietary treatments. The P supplementation either from DCP (T<sub>1</sub>), bone meal (T<sub>2</sub>), mustard oil cake (T<sub>3</sub>), sesame oil cake (T<sub>4</sub>) or poultry litter ((T<sub>5</sub>) had no significant effect on organic matter (OM) and CP intake. The apparent digestibility of DM and OM were significantly (P<0.05 and P<0.01) affected by the supplementation of P either from DCP, bone meal, mustard oil cake, sesame oil cake or from poultry litter. But the digestibility of CP, CF, NFE and EE was not significantly (P>0.05) affected by the supplementation of P from these sources. There was no significant (P>0.05) difference in DCP and DCF contents among the dietary treatments. The apparent absorption of P (g/100g) was significantly (P>0.05) higher for dietary groups T<sub>2, </sub>T<sub>3 </sub>and T<sub>5 </sub>(74.50) than T<sub>0 </sub>(62.16), T<sub>1 </sub>(73.15) and T<sub>4 </sub>(70.16%). The true absorption of P for supplemented diets (T<sub>1, </sub>T<sub>2</sub>, T<sub>3 </sub>and T<sub>5</sub>) was numerically higher than the diet T<sub>0</sub>, and T<sub>4</sub>. P balance was significantly (P<0.01) higher for diets T<sub>1 </sub>(9.11 g/d), T<sub>2 </sub>(10.87 g/d), T<sub>3 </sub>(9.65g/d), T<sub>4 </sub>(8.62g/d) and T<sub>5 </sub>(11.16g/d) compared to diet T<sub>0 </sub>(2.75 g/d). The bioavailability of P from control diet, DCP, bone meal, mustard oil cake, sesame oil cake and poultry litter were 62.16, 80.46, 81.97, 81.84.75.22 and 81.47%, respectively among the test materials. It may be concluded that bone meal, mustard oil cake and poultry litter may be used as phosphorus supplement in cattle ration.</p> <p class="Default">DOI: <a href="http://dx.doi.org/10.3329/bjas.v38i1-2.9910">http://dx.doi.org/10.3329/bjas.v38i1-2.9910</a></p> <p class="Default"><em>BJAS </em>2009; 38(1-2): 33-41</p>}, number={1-2}, journal={Bangladesh Journal of Animal Science}, author={Rahman, MA and Khandaker, ZH and Khaleduzzaman, ABM}, year={2012}, month={Feb.}, pages={33–41} }
