Abstract
- Eighteen indigenous growing cattle of two years old having initial live weight of 100 ± 4.5 kg were used to investigate the bioavailability of phosphorus from different sources (Di-calcium phosphate, Bone meal, Sesame oil cake, Mustard oil cake and Poultry liter) and its effect on the nutrient utilization and phosphorus balance of cattle. 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 : T0 (control diet), T1 (Control + DCP), T2 (Control + Bone meal), T3 (Control+ mustard oil cake), T4 (Control+ sesame oil cake) and T5 (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 T1, T2, T3, T4 and T5, 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 T0 and the highest value was recorded for diet T5 and significantly (P0.05) 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 T2, T3 and T5 (74.50) than T0 (62.16), T1 (73.15) and T4 (70.16%). The true absorption of P for supplemented diets (T1, T2, T3 and T5) was numerically higher than the diet T0, and T4. P balance was significantly (P
