Citrus pulp feed is nutritious, can not only be used for feed additive and feeds nonruminant, can raise as essence again Material feeds complex stomach animal.Generally citrus pulp feed is divided into fresh feed, dry feed, 3 kinds of fermented feed.Citrus chachiensis Hort. Fructus Citri tangerinae processing waste residue is mainly composed of cellulose, and the arrangement of its glucose subunit the most in order, forms similar crystal Fluid-tight structure, therefore cellulose can not be dissolved in water, it is difficult to is digested by nonruminants such as chicken, pig, ducks.

Originally research and propose and first breed in offsucm of citrus with aspergillus niger, be further cultured for geotrichum candidum fermenting and producing list The method of cell protein.It is aobvious that the feedstuff prepared has higher nutritive value, particularly single cell protein content Write and improve, and low cost, pollution-free, be conducive to improving the comprehensive utilization degree of mandarin orange, raw for recyclability Goods and materials source is converted into the channel of single cell protein and newly-increased hay varieties offer feasibility.

Citrus pulp fermented fodder nutrient Gao Erquan, compared with unfermentable dry powder, thick protein improves 50%, Aminoacid improves 55%, and crude fat improves 24%, and vitamin improves 10%-60%, and crude fibre declines 17%, Illustrate that fermentation energy makes up dry powder protein, amino acid whose deficiency, and increase vitamin content so that it is nutrition reaches To higher level.In order to feeding cow, the Semen Maydis powder of 40%-45%, and milch cow fur light can be replaced, anti- Sick power strengthens.

(3) summary of the invention:

It is an object of the invention to provide a kind of natural fermented feedstuff containing Citrus waste residue, citrus peel residue ferments Feedstuff crude protein compared with unfermentable citrus peel residue improves 50%, and aminoacid improves 55%, and crude fat improves 24%, vitamin improves 10%-60%, and crude fibre declines 17%.After showing that citrus peel residue is fermented, its nutrition Reach higher level, represent Semen Maydis with concentrated feed compared with, skin residue fermented feed crude protein is high by 14%, and aminoacid is high 46%, crude fat is high by 25%, and calcium is high 40 times, and phosphorus is high 9 times, and ferrum is high 26 times, and zinc is high 5 times, and vitamin is high 3-20 times, better than Oryza glutinosa.In citrus peel residue fermentation protein feedstuff in addition to containing rich in protein, also Containing more enzyme, vitamin, inorganic elements and a small amount of nucleic acid material.

Technical scheme: a kind of containing Citrus produced by fermenting waste residues feedstuff, it is characterised in that it is by Citrus Waste residue is through the natural fermented feedstuff of specified microorganisms fermentation of Aspergillus niger.
