We discussed the optimization of biological feed fermentation conditions with combined bacterium of Lactobacillus plantarum and yeast,and studied the effects of the strains ratio,initial charge,water content,fermentation temperature,inoc-ulation size and sodium humate amount on the viable count of fermentation product.The results showed that the optimum fer-menting parameter of biological feed were as follows:the ratio of Lactobacillus plantarum∶yeast of 1∶1,initial charge 50 g,water content 50%,fermentation temperature 34℃,inoculation size 10%,and sodium humate amount 2%.Under the condi-tions,biological feed with combined bacterium contained Lactobacillus plantarum 17.59×108 cfu/g and yeast 8.84×108 cfu/g.
