The effects of their metabolic product on bacteria resistance and antibacterial spectrum were studied, the bacillus and lactic acid bacteria was matched which will have different antibacterial spectrums. Their effects on animals were detected. The bacillus B7348 and lactic acid bacteria LP11 with high activities of bacteria resistance were selected through the test, the matched bacillus B7348 and lactic acid bacteria LP11 can replace the use of antibiotics in animal feed. Its effect was better than feed antibiotics in terms of improving the body resistance and reducing incidence of diseases.
