The invention relates to a composite probiotics feed additive containing lactic acid bacteria. The composite probiotics feed additive is prepared by spraying, freezing, drying and compounding 40-60% of lactobacillus acidophilus, 15-20% of lactobacillus amylophilus, 5-10% of lactobacillus salivarius, 5-10% of streptococcus thermophilus, 5-10% of bacteroides thetaiotaomicron and 5-10% of glucose. All strains are separated from pig intestines chime. With the consideration of each part of an intestinal canal of animal, the lactic acid bacteria which produce lactic acid of the front section of the intestinal canal are combined with the bacteroides thetaiotaomicron which dissolve cellulose and polysaccharide of the rear section of the intestinal canal, the proportion among the bacteria is similar to the composition of corresponding bacteria in the intestinal canal of a healthy animal, so that the respective advantages can be developed well, the health of the animal is improved further, the feed digestibility is improved, and the production performance of the animal is improved.
