Effect of Reconstitution on the Bioavailability of Nutrients from High Tannin Sorghum in Adult Japanese Quails

A metabolic trial was conducted using adult Japanese quails to explore the effect of reconstitution process on the nutritive value of high tannin red sorghum (HTRS). About 90 adult Japanese quails (15 weeks of age) were fed with HTRS and reconstituted red sorghum (RRS). No significant difference was observed in apparent metabolizable energy (AME) and nitrogen corrected apparent metabolizable energy (AMEn) values. The true metabolizable energy (TME) and nitrogen corrected true metabolizable energy (TMEn) values of RRS were significantly higher (P<0.05 to 0.01) than the HTRS. Reconstitution had no effect on protein digestibility. The availability of calcium from HTRS was markedly higher (P<0.01) as compared to RRS. The availability of magnesium and manganese from reconstituted sorghum were significantly higher (P<0.05) than unprocessed red sorghum. Reconstitution had no effect on copper and phosphorus utilization. From the present study it is concluded that reconstitution does not exert any appreciable effect in enhancing the nutritive value of red sorghum.
