Preparation method of sheep feed additive fermented by probiotic

Abstract

The invention discloses a preparation method of a sheep feed additive fermented by probiotic. The preparation method comprises the following steps: (1) taking corn bract, locust leaf, elm leaf, mulberry leaf, and alfalfa as the raw materials, washing, drying in the shade, and chopping; (2) evenly mixing the raw materials together, adding water, and grinding to prepare slurry; (3) adding bacillus subtilis and aspergillus oryzae into the slurry, stirring, sealing, and fermenting to obtain fermentation broth; (4) inoculating a lactobacillus acidophilus nutritional solution to the fermentation broth to obtain a primary fermentation broth; (5) adding sodium chloride into the primary fermentation broth, fully stirring, carrying out fermentation at a normal temperature to obtain a secondary fermentation broth, filtering, recycling the filtrate, and saving the filtrate at a temperature of 2 to 10 DEG C. The sheep feed additive can improve the palatability of feeds, strengthen the permanent planting ability of probiotics in intestines, promote the digestion and absorption, enhance the immunity and performance on resisting diseases, and reduce the morbidity; moreover, the raw material resources are stable, and the prices are cheap.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a preparation method of a sheep feed additive fermented by probiotics.

Problems solved by technology

Therefore, the development of the sheep raising industry continues to grow. With the development of the sheep raising industry, various sheep feed additives continue to pour into the market. A considerable part of the existing sheep feed additives is composed of antibiotics and trace elements. This type of feed additive Although it can effectively prevent the occurrence of diseases after use, improve animal production performance, and improve sheep breeding benefits, the long-term use of antibiotic additives can easily lead to drug resistance of many pathogenic bacteria, imbalance of normal flora in the digestive tract of livestock and poultry, and make livestock and poultry Decreased immune function and severe drug residues in sheep will seriously damage the health of sheep and humans

As many problems caused by the use of antibiotic additives have been reported, relatively safe Chinese herbal medicine feed additives have begun to appear on the market. Some Chinese herbal medicines are relatively expensive, resulting in increased breeding costs. Side effects, leading to the reduction of mutton quality, and pose a greater threat to food safety
