An investigation was conducted to assess the economics of production of lactating dairy cows fed on paddy straw plus non-forage fibre sources (NFFS) based complete rations containing different levels of neutral detergent fibre (NDF). The study was conducted for a period of six months in 18 lactating dairy cows, divided into three groups of six each, by feeding them on paddy straw plus NFFS based complete rations containing different levels of NDF, in two phases of three months (90 days) each, being the early and mid lactation phases, respectively. Three isonitrogenous and isocaloric complete rations, T1, T2 and T3 with 25, 30 and 35 per cent NDF, respectively formulated as per ICAR-NIANP (2013), were fed to the experimental animals. Individual records of daily dry matter intake and milk production were maintained throughout the experiment. From the data gathered on these two parameters, in the two phases, the cost of feed per kilogram of milk produced was worked out. Data gathered on the various parameters, in the two phases were analysed statistically as per Snedecor and Cochran (1994) by analysis of variance (ANOVA) technique, using the software, statistical product and service solutions (SPSS) version 21.0. The cost per kg of milk produced by the cows fed on the three experimental rations; T1, T2 and T3 in phase I, phase II and the total experiment were, Rs. 28.58, 28.50, 29.70; 35.08, 34.05, 33.72 and 31.89, 31.27, 31.73, respectively, with the values in the three dietary treatments being similar (P>0.05). An overall critical evaluation of the results of both the phases as well as the total experiment revealed that the animals in all the three dietary treatments performed well and suggest that complete rations containing paddy straw as the sole source of roughage, with 25 to 35 per cent NDF can be recommended for use among early and mid lactation dairy cows.
