Embodiment 1

[0031] A compound microbial feed additive, prepared from the following raw materials in parts by weight: 30 parts of lactic acid bacteria fermentation liquid, 15 parts of jelly-like Bacillus fermentation liquid, 10 parts of Trichoderma longibrachiae fermentation liquid, and 20 parts of chlorella algae liquid;

[0032] Among them, the number of effective viable bacteria in the fermentation liquid of lactic acid bacteria and the fermentation liquid of jelly-like bacillus was 2.6×10 10 CFU / mL; the amount of spores in Trichoderma longibrachiata fermentation broth is 1.0×10 8 individual / mL; the concentration of Chlorella algae liquid is 1.8×10 5 individual / mL.

[0033] The specific preparation method is as follows:

[0034] Step 1, preparing lactic acid bacteria seed liquid and jelly-like bacillus seed liquid respectively;

[0035] Step 2, preparing lactic acid bacteria fermentation broth

[0036] Inoculate the lactic acid bacteria seed liquid into the YPD liquid medium, and th...

Embodiment 2

[0048] A compound microbial feed additive, prepared from the following raw materials in parts by weight: 40 parts of lactic acid bacteria fermentation liquid, 10 parts of jelly-like Bacillus fermentation liquid, 12 parts of Trichoderma longibranchus fermentation liquid, and 25 parts of chlorella algae liquid;

[0049] Among them, the number of effective viable bacteria in the lactic acid bacteria fermentation liquid and jelly-like Bacillus fermentation liquid was 1.0×10 10 CFU / mL; the amount of spores in Trichoderma longibrachiata fermentation broth is 1.0×10 9 individual / mL; the concentration of Chlorella algae liquid is 1.5×10 5 individual / mL.

[0050] Concrete preparation method is the same as embodiment 1, and difference is that the formula of embodiment 1 is changed into embodiment 2, simultaneously, the preparation method of jelly-like bacillus fermented liquid is as follows:

[0051] Dried persimmon skin is ground into powder, and passed through a 20-mesh sieve to obt...

Abstract

The invention discloses a compound microbial feed additive, which is prepared from the following raw materials in parts by weight: 30-50 parts of lactic acid bacteria fermentation liquid, 10-15 parts of jelly-like Bacillus fermentation liquid, and 10-15 parts of Trichoderma longibrachia fermentation liquid 20‑30 parts of chlorella algae liquid. The invention also provides a preparation method of the compound microbial feed additive. The compound microbial feed additive provided by the invention can improve the intestinal function of piglets, increase the daily weight gain and feed conversion efficiency of weaned piglets, and has significant antibacterial and antiviral effects, can significantly improve the immunity of piglets, and effectively prevent piglets from Diarrhea occurs after weaning, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of animal feed processing, and in particular relates to a compound microbial feed additive and a preparation method thereof. Background technique [0002] Microbial feed additive is a special feed additive, which promotes the growth of farmed animals through the physiological metabolism of microbial strains, reduces the use of drugs, improves the quality of farmed animals, and realizes green farming. Because microbial feed additives have so many excellent characteristics, more and more researchers have started research in this area, especially the research on the application of microbial feed additives in pig industry has become a current research hotspot. [0003] In the pig industry, in order to reduce the transmission of disease from sows to piglets, piglets aged 3-5 weeks are weaned. However, piglets after weaning often suffer from diarrhea due to their imperfect digestive function and low immunity. Aff...
