Five groups with five animals in each, under completely randomized design were fed A, B, C, D and E rations which were iso nitrogenous and isocaloric based on NDF levels 23, 28, 33, 38 and 43%, respectively. Nutrient intake and nutrient digestibility differ (P&lt;0.001) significantly among the dietary groups. Dry matter (DM), crude protein (CP) and neutral detergent fibre (NDF) intake (kg/d) were found highest in animals fed diet C (14.31&plusmn;0.05), C (1.86&plusmn;0.006) and E (5.52&plusmn;0.018) respectively than those on the other four treatments. Whereas, DM, CP and NDF digestibility percentage were observed the highest in the group B (62.88&plusmn;1.04), B (51.00&plusmn;0.57) and C (64.4&plusmn;0.99) respectively, as compared to others. The 4% fat corrected milk (kg/day) production was significantly (P&lt;0.001) higher in group A (11.23&plusmn;0.15) as compared to others. In term of milk composition (TS 16.65&plusmn;0.07%, fat 7.01&plusmn;0.04%, milk protein 3.78&plusmn;0.02% and milk lactose 5.04&plusmn;0.02%) were observed the highest in group D (38% NDF). Hence it is concluded that 33% NDF level is better in terms of NDF digestibility and 23%NDF in terms of 4%FCM production in early lactating Nili Ravi buffaloes.</p> Nili Ravi buffaloes, NDF, ADF, voluntary intake, weight gain Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2014-JAPS-145
