Abstract: Abstract：0bjective To explore the possibility of applying the bacterial protein ZGB to breeding industry as the protein feed．Methods Mice administrated with residue degradation products of penicillin bacteria at different doses were monitored continuously，and their body weight and deaths were recorded every 10 days．At the end of the experiment，the internal organs of the mice sampled randomly were weighted，and the organ coefficients were calculated．Simultaneously，the related physiological and biochemical indicators of blood were measured．Results (1)Mice in each group were in good spirits，and their feed intake，water consumption，hair coat and feces were normal．Most of the mice survived except that one administrated with 6％bacterial protein ZGB died．(2)Among the groups，there was no significant difference(P>0．05)in body weight．(3)The blood physiological and biochemical indicators were no significant difference(P>0．05)among groups．(4)Compared with the control group，the organ coefficients of treatment groups were no significant difference(P>0．05)．Conclusion The bacterial protein ZGB has a slight effect on body weight and blood physiological and biochemical indicators of mice． Key words：Bacterial protein ZGB；Mice；Physiological and biochemical indicators；Organ coefficient
