(1) Oil-tea-cake being ground into meal, soaking 5-6 hour, mechanically except the impurity such as shelling, then ammoniacal liquor being mixed with suitable quantity of water, regulate PH to be 10, mix with above-mentioned Oil-tea-cake meal, soak 8 hours, filter, dry, make micro mist, Oil-tea-cake powder must be improved;
(2) bracteal leaf of corn is mixed with vinegar and suitable quantity of water, grind to form juice, then mix with blood meal, sweet orange peel, bafillus natto, sealing, 35 DEG C of condition bottom fermentations 48 hours, leach sweet orange peel, again remaining slurries are carried out high-pressure homogenization process, obtain fermentation homogenate;
(3) the fermentation homogenate of the improvement Oil-tea-cake powder of step 1 and step 2, saccharomycete are mixed, sealing, continue fermentation 1-2 days under 30-40 DEG C of condition, dry, obtain mixed culture fermentation powder;
(4) the fermentation sweet orange peel of step 2 is added suitable quantity of water grinding pulping, then corn is carried out Ultramicro-powder be broken into 60-70 order, starch with above-mentioned orange peel, alphalise starch, fish starch and mix, oven dry, granulation, obtains premix particle;
(5) make powder after being dried by lotus rhizome, add suitable quantity of water and soak 5-6 hour, after seepage pressure effects, obtain lotus rhizome extract;
(6) expanding treatment is carried out after being mixed by remaining to feather meal and step 5 lotus rhizome granulated slag; mix with the lotus rhizome extract of step 5, the mixed culture fermentation powder of step 3 and other residual components again; dry granulation, then mix with the premix particle of step 4.
Beneficial effect of the present invention:
In the present invention, tea seed episperm is the main source of crude fibre and tannin in grouts, has had a strong impact on palatability and the trophism of grouts, can improve the quality of feed after shelling.With ammoniacal liquor soak Oil-tea-cake, add the content of nonprotein nitrogen in grouts, the part ester bond of ammonia also in decomposable asymmetric choice net grouts on lignin in addition, grouts are softened, the digestibility of leech to feed can be improved by ammoniated treatment, improve digestibility and the capacity usage ratio of the organic substance such as digestibility and crude fibre of thick protein.The pH value of soak is adjusted to the residual quantity that 10 are conducive to reducing saponin in cake cypress.By bracteal leaf of corn lapping liquid and blood meal fermentation liquid, the slurries after homogenized disperse in particulate form, make active ingredient stable in properties, are uniformly dispersed.Grouts after ammonia process process are carried out inoculation fermentation, and saccharomycete can utilize nitrogenous source in grouts and carbon source, the nutrients such as producing strains body protein.Reduce the content of crude fibre, saponin.In addition, the fermentation of yeast produces certain wine flavour, in drying course, because some chemical reactions can produce baking fragrance, improves the nutritive value of grouts, improves the local flavor of grouts.By starch based material through Crushing of Ultrafine, enhance starch material and other formula components adhesions, then with fish starch mix after granulate, temperature controls at 60-70 DEG C, and water stability is good.The fish slurry added substitutes all or part of amount of water, makes material mouthfeel and taste closer to natural bait.
