High yielding crossbred cows are fed high amount of concentrate which poses metabolic disorders. TMR feeding is suitable for high concentrate feeding. RFI is a measure of efficiency which has not been explored in crossbred cows. Therefore present study was undertaken to study the effect of TMR feeding of performance and RFI in crossbred cows. Twelve cows were divided in to two groups of six animals each and fed ration with 60:40 roughage: concentrate ratio. The animals were fed individually and daily feed intake and refusal were recorded. The DM intake was calculated. The data showed that the DM intake of was similar in both the groups. On DMI basis, RFI, when calculated on DMI basis, was significantly (P <0.05) lower in TMR as compared to NON-TMR. The digestibility of DM, CP, ADF, NDF and TDN was significantly (P <0.05) higher in TMR as compared to NON-TMR. The TMR feeding had significantly positive (P <0.05) effect on milk production, and milk energy yield. The RFI had negative correlation with intake and digestibility parameter of ration.
