▎ 摘　　要

NOVELTY - Microbial fermented feed comprises 80-100 pts. wt. soybean residue, 10-15 pts. wt. rice bran, 15-25 pts. wt. corn powder, 0.1-0.3 pt. wt. table salt, 0.05-0.1 pt. wt. graphene quantum dot, 1-3 pts. wt. traditional Chinese medicinal composition and 1-3 pts. wt. complex microbial inoculum. The traditional Chinese medicinal composition comprises Rosa roxburghii root, trifoliate orange, shepherd's purse, elecampane, Hippophae rhamnoides, Potentilla fruticosa leaves, Aronia, Litsea cubeba, thyme, black sesame, rhizoma atractylodis, dried orange peel and pine needle. The complex microbial inoculum comprises Bacillus subtilis, Streptococcus faecalis, Lactobacillus and lactic acid bacteria. USE - The microbial fermented feed is useful for feeding two-end-black pigs (claimed) for modulating digestive system. ADVANTAGE - The microbial fermented feed has improved nutritive value of the soybean residue and improves disease resistance and economic value of the two-end-black pigs. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for preparing the microbial fermented feed involves (a) weighing the raw materials of traditional Chinese medicinal composition, immersing in 8-10 times water, extracting and filtering to obtain medicinal liquid and filter residue, (b) adding complex microbial inoculum into the medicinal liquid, soybean residue, rice bran, corn powder and table salt, stirring uniformly, sealing and fermenting for 2-10 days to obtain fermentation product, and (c) adding the filter residue into the fermentation product, embedding with graphene quantum dot, drying and granulating to obtain product; and (2) use of the microbial fermented feed for feeding of two-end-black pigs of different types, where the piglet adopts free feeding, less release and frequent addition, the feed rate of pigs in the fattening period is 1-2.5 kg/day, the feeding rate of pregnant sows is 1.5-2.2 kg/day, the feeding rate of lactating sows is 3-3.5 kg/day and the feeding rate for breeding boars is 2-2.5 kg/day.
