Problems solved by technology

The crude fiber content and firewood properties of the extracted ginkgo leaf residue increase. In the development of products, it is thought that the digestion, absorption and utilization of animals after feeding are the key. The biological fermentation process in the prior art, due to the proliferation of microorganisms and metabolism, increase the protein in the feed, the fiber only has a softening process in the fermentation process, and the indigestible fiber components are still difficult to digest and absorb. Undoubtedly, the ginkgo biloba residue can not be fully utilized. , Various factors in the microbial fermentation process cause uncertainty and great instability in the number of viable bacteria

Abstract

The invention belongs to the field of deep processing of agricultural products and relates to the field of animal feed processing, in particular to a biological feed additive, a preparation method of the additive and application of the additive to animal feed. The biological feed additive is prepared in the way that water-soluble ginkgo leaf residue feed dietary fiber or water-insoluble ginkgo leaf residue feed dietary fiber is uniformly mixed with a compound microbial bacterium at the weight ratio of (5-10) to 1.5 to obtain a mixture and the mixture is directly pressed in a dry granulator into granules with the particulate size of 80-90 meshes or 65-85 meshes. The preparation method solves the problem about recycling treatment of ginkgo leaf residue. The ginkgo leaf residue is converted into water-soluble and water-insoluble ginkgo leaf residue feed dietary fiber, and the dietary fiber is mixed with the beneficial compound microbial bacterium to prepare the biological feed additive, so that the good application of waste resources is realized and remarkable economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the field of agricultural product processing, specifically relates to the field of animal feed processing, in particular to a biological feed additive, a preparation method of the additive and an application of the additive in animal feeding. Background technique [0002] Ginkgo biloba has high nutritional value and medicinal value. It contains 46 kinds of flavonoids, terpenoids, phenols, trace elements and amino acids and other active ingredients. Its nutritional content is also very rich. On a dry basis, Ginkgo biloba Protein 10.9%~15.5%, total sugar 7.38%~8.69%, reducing sugar 4.64%~5.63%, vitamin C66.78~129.20mg / 100g, vitamin E6.17~8.05 mg / 100g, vitamin B 1 0.06~0.09 mg / 100g, vitamin B 2 0.30~0.45 mg / 100g, carotene 14.52~18.80 mg / 100g, choline 28.00~39.50 mg / 100g.
