MINERAL ANALYSIS OF ENSILED RICE MILLING WASTE ENHANCED WITH NON-PROTEIN NITROGEN SOURCES

Abstract

An experiment was conducted to examine the effects of Urea and Poultry litter (PL) in enhancing the physiochemical qualities and mineral contents of ensiled rice milling waste (RMW) in a completely randomized design (CRD). RMW was treated with four different proportions of Urea and PL, which were ensiled in in-vitro laboratory silo (946ml). The treatments were; A (100%RMW), B (100%RMW+ Urea), C (80%RMW + 20%PL) and D (60%RMW + 40%PL). The treatments were ensiled for 21 days and analysed for physical properties and mineral compositions. Results showed that, higher (P<0.05) values of temperature and pH were reported in treatment D while lower values were obtained in treatment A. Treatment C has good temperature, pH, dark brown colour and sweet aroma. There was no significant difference (P > 0.05) in the Calcium content except for treatment C. Significant differences (P<0.05) were recorded for both Phosphorus and Sodium contents of the compounded silages. Treatment D leads in Phosphorus content, while treatment A leads in Calcium content. It is concluded that, treatment C (80%RMW + 20%PL) should be used to enhance the nutritional quality of ensiled rice milling waste. Hence, it is recommended for dry season ruminant feeding.
