COMPARATIVE-EVALUATION OF BATCH AND CONTINUOUSLY OIL-EXTRACTED RICE BRAN IN CATTLE RATION

The nutritive values of differently processed deoiled rice brans (DRB) have been evaluated by conducting a metabolic trial on 15 adult cross bred male carves divided into 3 groups. Group 1 was fed on continuous type DRB along with oat fodder, group 2 on batch type DRB with oat fod der and group 3 (control) on oat fodder alone. The digestibility coeff icients of rice brans were worked out by deducting the values estimate d for oat fodder. OM and CP digestibilities of continuous DRB (60.27 a nd 64.77) were significantly higher than those of batch type DRB (53.5 2 and 43.26). However, no significant difference was observed in EE, C F and NFE digestibilities. DCP and TDN contents of continuous DRB (10. 88 and 56.64%) were significantly higher than those of batch type DRB (6.41 and 47.56%) indicating that continuous DRB is a cost-effective r esource as animal feed in terms of available protein and total digesti ble nutrients.
