Preparation method of probiotic fermentation pig feed additive

Abstract

The invention discloses a preparation method of a probiotic fermentation pig feed additive. The method comprises the following steps: pre-processing; taking 30-50 parts of locust tree leaf, 30-50 parts of peanut stalk, 20-40 parts of sweet potato vine, 10-30 parts of purslane, 5-15 parts of leaf of Broussonetia Papyrifera, 10-20 parts of pumpkin leaf, 5-10 parts of wild chrysanthemum flower and 20-30 parts of Herba Plantaginis, mixing to obtain a mixture, adding rice washed water having same amount with the mixture, and carrying out pulp refining to obtain a pulp; adding Bacillus subtilis and Aspergillus niger to the obtained pulp, and fermenting to obtain a fermentation stock solution; inoculating a Lactobacillus acidophilus nutrient solution into the fermentation stock solution, and fermenting to obtain a primary fermentation solution; and adding sodium chloride to the primary fermentation solution, carrying out standing fermentation to obtain a secondary fermentation solution, filtering, and recovering and preserving the above obtained filtrate. The additive can increase the nutritional components of feeds, promotes growth, improves the utilization rate of the feeds, enhances the colonization ability of beneficial bacteria in the intestinal tract, promotes digestion and absorption, enhances immunity, improves the disease resistance of bodies, reduces the incidence of diseases, and has no toxic side effects or untoward effects.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a preparation method of a pig feed additive fermented by probiotics. Background technique [0002] my country is one of the largest breeding countries in the world. In my country's breeding industry, pig breeding accounts for a large proportion, which drives the rapid development of the feed industry. At present, there are various kinds of pig feeds on the market. Pigs of different growth stages There are specific feeds. Most of the existing pig feeds are supplemented with antibiotics. Although the pig feeds with antibiotics can achieve better feeding effects, it is followed by problems of drug residues, drug resistance of pathogens, and environmental problems. , the imbalance of normal flora in the digestive tract of livestock and poultry, the decline of immune function of livestock and poultry, and the serious drug residues in pigs, which seriously dama...
