Detailed description of the invention

The following detailed description of premixed feed and preparation method thereof and the embodiment of poultry according to the present invention

First the premixed feed of poultry is according to a first aspect of the present invention described, it comprises complex mineral element, B B-complex, complex enzyme and carrier.

In poultry premixed feed according to a first aspect of the present invention; chitooligosaccharide-is obtained by the product degradation of chitosan that chitin is deacetylated; also be unique a large amount of basic amine group polysaccharide existed in natural sugar, good water solubility, directly absorbs by animal intestinal epithelial cell.The application of chitooligosaccharide-in poultry feed, can improve production performance, strengthen immunity of organisms and reduce cholesterol etc., therefore develop it and have larger potentiality and wide application prospect as novel fodder additive.

The preparation method of the premixed feed of poultry is according to a second aspect of the present invention described again.

In the preparation method of the poultry premixed feed of second aspect present invention, it comprises the following steps: pulverized by various raw material, crosses 80 mesh sieves, obtains powder-material; Powder-material is weighed by proportioning, mixing; By the powder-material of mixing by being steam heated to 70 ~ 90 DEG C, obtain particle; Obtained particle is carried out cool, classification, packaging, obtain final products.

Embodiment according to the premixed feed of poultry of the present invention and preparation method thereof and comparative example are finally described.

First chitooligosaccharide-is prepared:

With dry shrimp shell for raw material, pulverize the fragment into about 4 × 4mm2 size, cross 50 mesh sieves, shrimp shell after sieving loads 50 object nylon net bags, soaks 20 hours under room temperature in 9%NaOH solution, filters, dries, be flushed to neutrality with clear water afterwards, then dry, complete alkali treatment and take off albumen operation.The fine powder sieved, as concentrated feed, is the first byproduct; Filtrate is adjusted to pH=6 ~ 7 with dense HCL and makes protein precipitation, sediment separate out, and washing, about 70 DEG C forced air dryings, can obtain protein, are the second byproduct.

Be dissolved in by EDTA in NaOH solution, obtained saturated solution (pH=7), take off carrying out alkali treatment in the shrimp shell immersion EDTA saturated solution of albumen operation, immersion treatment 20 hours under room temperature, filters, dries, complete EDTA process decalcification operation.

Alkali treatment and EDTA process decalcification operation repeated once, and the wet feed obtained after process is added 55%NaCH solution, about 55 DEG C process 16 hours; Then filter, then with newly joining 55%NaOH solution, about 55 DEG C process 16 hours, filter, clear water was washed till neutrality, and dry, about 70 DEG C forced air dryings, obtain white shitosan finished product, deacetylation DD > 65%.

Based on company's bacterial classification, through UV and nitrite mutagenesis (NTG) complex mutation and Protoplast fusion, the high productive mutant that seed selection makes new advances, this bacterium have produce that chitosan enzyme is rapid, cultivation cycle is short, selectivity is strong, vigor is high, oligosaccharides conversion ratio and the high characteristic of recovery rate, cultivate 36 hours, thick enzyme activity can reach 860 μ/ml.In 1000L retort, in 60 DEG C, pH6.5, concentration of substrate 25%, adds enzyme by 1ml enzyme liquid/15g shitosan, in 8h, shitosan is converted into feed chitooligosaccharide-.
