Abstract: The objective of this work was to investigate the effects of sugarcane tops silage and corn straw silage on the growth performance, digestibility and metabolisability of nutrient and blood biochemical indexes of growing buffalo.Trial 1:21 buffalos were randomly divided into 3 groups according to the principle of body weight and birth similarity for 30 days feeding trial.The buffalos in 3 groups were fed with SS+concentrate, CS+concentrate and SS+CS +concentrate, respectively.Trial 2:Six buffalos were randomly divided into 2 groups according to the principle of body weight and birth similarity, and fed with SS and CS, respectively.There were 4 days for digestion-metabolism trial using total feces collection methods.The results showed that:①There were no significant difference on average dry matter intake(ADMI)of buffalos fed with CS and SS(P>0.05), but comparing with SS, the average daily gain(ADG)was higher of buffalos fed with CS(P>0.05).Both ADMI and ADG were higher when buffalos fed with CS+SS.②Compare to SS, the nutrient digestibility, nitrogen metabolization and energy metabolic rate of CS were higher.And the effects of SS and CS on the digestibility of NDF, ADF were no significant difference(P>0.05).③The effect of feeding with CS, SS on blood biochemical indexes were no significant difference, and did not have any bad effect on animal body.Thus the digestibility of nutrient was higher when fed with CS, and SS and CS separately had no bad effect on blood biochemical indexes.Feeding SS+CS could improve the growth performance of growing buffalo.
