The invention discloses a method for recovering filamentous bacterial expansion of moderately halophilic aerobic granular sludge, and belongs to the technical field of high-salinity wastewater treatment. The method aims at the problem of sludge bulking caused by the fact that filamentous bacteria and lactic acid producing bacteria Halolacbacillus sp. Grow synergistically in a high-salt environment, and the Halolacbacillus sp. Secretes lactic acid to induce overgrowth of the filamentous bacteria, and the rapid proliferation of fungi is promoted by controllably reducing the salinity of a system. Fungus hyphae extend in the particles to form an oxygen conveying channel, the anaerobic area is improved, the living space of the Halolabacillussp. Is compressed, and lactic acid supply of filamentous bacteria is cut off to inhibit growth of the filamentous bacteria. In this way, the structure of the moderately halophilic aerobic granular sludge with filamentous bacterial expansion can be recovered and strengthened in a short time. The method is a non-toxic, low-cost, simple-to-operate, safe, efficient, stable and reliable regulation and control mode.

The invention discloses a feed additive for preventing and treating ruminant rumen acidosis and application thereof, and belongs to the technical field of feed additives for livestock, and the feed additive is based on the theory of'spleen tonifying and heat clearing 'of traditional Chinese medicine and follows the principle of'monarch, minister, assistant and guide'. Monarch drugs such as radix astragali and radix codonopsis tonify qi and invigorate the spleen to consolidate the root, ministerial drugs such as rhizoma atractylodis, fructus crataegi and pericarpium citri reticulatae eliminate dampness and remove food retention to reduce phlegm, adjuvant drugs such as rhizoma coptidis, cortex phellodendri and gypsum are creatively introduced to clear heat, eliminate dampness, purge fire and remove toxin, and finally liquorice serves as a conductant drug to harmonize all the drugs. Compared with the prior art, the rumen micro-ecological balance and pH stability can be rapidly recovered and maintained for a long time from multiple ways of enhancing the digestion function, inhibiting lactic acid producing bacteria, promoting lactic acid utilizing bacteria and the like. The additive is completely prepared from natural Chinese herbal medicines, is safe, free of residues and good in palatability, has nutrition and health care functions, is simple in preparation process, is suitable for ruminants such as dairy cows and beef cattle, and provides an effective solution for green and healthy breeding.

The invention relates to the use of a probiotic composition comprising a lactic acid producing bacterial strain, a conditioned medium or microvesicles from the lactic acid producing bacterial strain in treatment or prevention of hyposecretinemia. The lactic acid producing bacterial strain, the conditioned medium and / or the microvesicles is or are capable of inducing release, and optionally production, of secretin locally in a gastrointestinal tract of a subject suffering from hyposecretinemia or having a risk of suffering from hyposecretinemia. The invention also relates to screening of lactic acid producing bacterial strains suitable in treatment or prevention of hyposecretinemia. Secretin
