Description Agro-industrial byproducts, viz. Mangifera indica (kernel), Acacia nilotica (pods), Prosopis jufiora (pods), Shorea robusta (cake), Madhuca indica (cake), Camellia assamica (waste), Tamarindus indica (seed meal), and Acacia nilotica (seed meal) were evaluated for compositional changes, fractionation of tannin and digestion kinetics. First 6 agroindustrial byproducts were also evaluated for compositional variation in amino acids profiles. Acacia nilotii'(l seed meal, Madhuca indica and Camellia assamica contained highest level of crude protein followed by Shorea robustCl, Acacia nilotica pods and Prosopis julmora. Ether extract was highest in Mangijera indica and lowest in Shorea robu.I'ta while crude fibre content W&S highest in Pro.;opisjul~fiora and lowest in Shorea robllsta. Mangifera indica and Camelia assamica contained high level of most essential amino acids. Lysine, cystein+methinoine, arginine and threonine content of Mangifera indica were 1.91, 7.65, 13.38 and 9.56g/l00g protein respectively (on OM). Its threonine and cystein+methionine were even higher than whole egg protein. Acacia nilotica contained highest level of total phenol and total tannin followed by Mang~fera indica and Slzorea robusta while others contained within the variation of range. In vitro DM and OM digestibility were highest in Man!5~f'era indica followed by Camelia assamica, Acacia nilotica seed meal, Acacia nilotica pods,Prosopis jufiora(flora and other showed below 50% digestibility. In vitro CP digestibility was highest in Acacia seed meal and low,- .;t in Mang(fera indica. In vitro gas production was highest in Camelia assamica followed by Acacia nilotica, Prosopis jufiora, Mang(t'era indica, Acacia seed meal, Shorea robusta, MadJzuca indica, Tamarindus indica during the first stage kinetic (0-24 h) while overall gas production in second stage kinetic (24-48 h) was highest in Acacia nilotica pods and lowest in Madhuca indica. However, overall gas production (0-48 h) was in the order of Mangzfera indica Acacia nilotica pods>Camelia assamica>Prosopis julU1ora>Shorea robllsta>Acacia seed meal>Madhuca indica>Talarindus indica. The mineral content was higher in Mallg(fera indica and Camellia assamica in comparison to other 4 byproducts. It is inferred that mangifera indica and Camelia assamica may he used as both energy and good source of essential amino acids while Prosopis jul~flora. Acacia nilotica seed meal, .horea robusta, Madhuca indica and Tamarindus indica as a source of protein, and Acacia nilotica pods both as a source of protein and energy.
