The application discloses an application of astragalus polysaccharide in promoting lactic acid bacteria metabolism and improving quality and stability of fermented products, and belongs to the technical field of fermented dairy product processing. The application adds 2 ‰ to 10 ‰ of astragalus polysaccharide and sucrose in skimmed milk with respect to the mass of the skimmed milk, inoculates lactic acid bacteria starter after pasteurization, and constant-temperature fermentation is carried out until the end point to prepare fermented products. The application utilizes the dual functions of astragalus polysaccharide in promoting lactic acid bacteria metabolism and strengthening milk protein gel network to realize the synergistic improvement of quality and stability of fermented products. Experiments show that when the addition amount of astragalus polysaccharide is 4 ‰, the sensory score of the fermented product reaches 87.3, and the water holding capacity is increased by 11.95 % compared with the control group; scanning electron microscopy shows that the gel network is dense and has few pores; when the addition amount is 6 ‰, the viable cell count reaches 1.23 x 10 8 CFU / ml; and when the addition amount is 8 ‰, the texture characteristics are optimal. The application is simple in operation, suitable for industrial production, and provides a new way for the development of functional fermented dairy products.

The invention provides a natural plant feed additive for improving immunity and promoting growth as well as a preparation method and application thereof, and relates to the field of feed additives, the natural plant feed additive is prepared from fourteen plant raw materials including gynostemma pentaphyllum, scandent hop, gentiana macrophylla, glossy privet fruit, flatstem milkvetch seed, sargentgloryvine stem, sea-buckthorn, astragalus membranaceus, radish seed, Chinese violet, humifuse euphorbia herb, ampelopsis japonica, paulownia flower and platycodon grandiflorum. The additive has multi-dimensional biological activity of promoting growth, enhancing immunity, resisting oxidation and protecting organs, can improve the growth performance of livestock and poultry by improving the average daily gain and reducing the feed-gain ratio to optimize the feed conversion rate, and can construct a humoral immune barrier by reducing the secretion of proinflammatory factors and increasing the level of anti-inflammatory factors to improve the immunity of livestock and poultry. According to the present invention, with the application of the composition, the protein and lipid metabolism disorder can be improved, the activity of ALT, AST and ALP can be reduced so as to protect the liver and the kidney and maintain the steady state of the body, the overall health level of livestock and poultry can be improved without the dependence on chemical agents, and the reliable technical support can be provided for promoting the development of the green, safe and efficient livestock and poultry breeding mode.
