Composite probiotics feed additive containing lactic acid bacteria and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a compound probiotic feed additive containing lactic acid bacteria and a preparation method thereof. Background technique [0002] A typical microbe colonizes every part of a healthy animal's gut and forms a beneficial symbiotic relationship with the animal. Due to the emergence of intensive high-density breeding methods, livestock are quite sensitive to the imbalance of intestinal flora, which leads to reduced digestion and absorption of nutrients and growth retardation. To overcome these difficulties, antibiotics are added to animal diets. It has also been shown to be quite effective in reducing diarrhea and promoting growth. However, the emergence of harmful microbial resistance has seriously interfered with the use of veterinary antibiotics, and the effectiveness of the antibiotic itself has also been reduced, and there are residual problems and the risk of cross-resistance with human pathogenic bacteria, thus affecting h...
