Stall feeding of ruminant is challenging due to shortage and/or supply of bulky roughages. Densely populated countries are losing both pasture and arable land and thereby feeding of ruminants are subjected to crop residue. In this vulnerable situation, alternative techniques of feeding are emerging need. Keeping this view, effective use of crop residues (straw and bagasse) were taken to produce compound pellet feed. Three types of straw pellet and bagasse pellets were prepared with the combination of concentrate feed at 60:40, 50:50 and 40:60 ratio of concentrate and roughage. Straw pellets comprised with a bit higher level of CP than that of bagasse pellet. Conversely, bagasse pellets discharged better energy in in vitro gas production technique than straw pellet. Addition of higher rate of concentrate increased significantly availability of digestible nutrients. Moreover, an in vibo digestibility trial was conducted to evaluate the nutritive values of compound pellets. T1 , T2 and T3 groups of animals were fed straw based pellet, bagasse based pellet and straw with concentrate mixture. Percent digestible nutrients (CP, CF, NFE and EE) and total digestible nutrients (TDN) were found better in straw pellet than that of bagasse pellet. N intake and retention was similar among all the groups but better was in T1 group. Straw pellet was found more effective than bagasse pellet or conventional straw feeding method.
