Abstract

The invention relates to a preparing method of a feed additive, in particular to a preparing method of a pig feed additive. The method includes the steps of mixing jasmine flower residues, wheat bran,rice bran and bean pulp, adding water to be evenly mixed to obtain a solid culture medium, sterilizing the solid culture medium for 30 min at 121 DEG C, cooling the solid culture medium to 28-30 DEGC, inoculating the solid culture medium with a saccharomyces rubrum seed solution and a trichoderma longibrachiatum rifai seed solution, evenly mixing the materials, flat laying the materials on a shallow plate, placing the shallow plate in a manual climatic box to be cultured, conducting low-temperature drying after culturing ends till the water content is 10% or lower, conducting pulverizing through a pulverizer to obtain fermented feed powder, evenly mixing the fermented feed powder, chicken liver powder and feed-grade bile acid, and conducting granulating and packaging to obtain a finishedproduct. The pig feed additive is high in palatability and has effects of promoting pig growth, improving pig immunity and improving pig carcase quality.

Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of a pig feed additive.

It is the main leftovers in the process of processing and producing jasmine tea. Jasmine slag is yellowish brown and has a strong jasmine fragrance. Some of them are used as animal feed, and most of them are discarded directly, causing a lot of waste and environmental pollution. The planting area of ​​jasmine in my country is about 120,000 mu, with an annual output of about 90,000 tons of flowers, and the annual output of jasmine tea is stable at between 110,000 and 120,000 tons. Such a large output of jasmine tea must produce a large amount of jasmine residue. Research It shows that the main nutrients such as aromatic substances, flavonoids and polysaccharides in jasmine dregs have basically...
