Abstract: Present study was carried out to develop a cost effective complete feed block with long shelf life using locally available fodder grasses and agricultural wastes. Three different complete feed blocks (T1, T2 and T3) were formulated to meet the daily requirement of 250kg heifers. Compacted blocks were formed in T1 and T2, while, T3 formed loose mass. The lowest (P< 0.05) free fatty acid content was observed in T2 while T3 had the highest. The highest (P< 0.05) dry matter, ash, ether extract, crude fiber and acid detergent fiber percentage were recorded in T1.
