Cassava stalk, manioc waste and herbage make the production method of stocker biological feedstuff
Technical field
The present invention discloses a kind of biological feedstuff production method, specifically utilizes crop by-products to produce the production method of stocker feed.
Background technology
Along with the raising of people's living standard, the demand of people to meat food is increasing, particularly the demand of high-grade meat, thus has effectively promoted the development of animal husbandry.The development of livestock breeding industry, needing a large amount of grain feeds for supporting, how to avoid livestock breeding industry and people to strive grain, opening up new feed resource, becoming the problem that people are concerned about.
A large amount of discarded objects is obtained after annual agricultural production results cereal, as the string such as stalk, shell class material, these materials are reproducible resources, and these materials are by after hydrolysis, a kind of material can be obtained---glucose sugar, and glucose is the energy matter of animal.If these string class materials are developed to feed, not only can save traditional feed resource, and can improve the ecological environment, form the benign cycle of agricultural production, promote the sustainable development of agricultural, animal husbandry.
Guangxi cassava industry occupies very important status in national cassava industry, and cassava cultivated area and output all account for more than 60% of the whole nation, is national maximum cassava production area.According to statistics, within 2012, Guangxi cassava cultivated area reaches 23.5 ten thousand hectares, produces fresh potato 5,600,000 tons per year, simultaneously the Cassava stalk of by-product more than 5,000,000 tons.Cassava stalk is except small part makes the provenance in the coming year, and major part is worked as firewood and burnt or abandon.Cassava stalk crude protein content is more than 5%, and crude fibre more than 20%, NFE more than 45%, has certain feeding value.But Cassava stalk quality is hard, and palatability is poor, can digestibility low.
Tapioca factory, cassava alcohol factory processing cassava process creates a large amount of manioc wastes, manioc waste crude protein content 2 ~ 5%, crude fat 1 ~ 2%, crude fibre more than 15%, manioc waste is nontoxic to be often used for originating as a kind of roughage of cheapness by plant, but because palatability is poor, indigestibility, livestock poor growth, many raisers can not store the manioc waste pulled back, just be deposited in outside film simply to cover, manioc waste within a couple of days with regard to yellowing, black (aflatoxins pollution), cause poisoning after feeding animals through often, morbidity is frequent.
Herbage, the particularly graminous pasture such as hybrid giant napier, napier grass, growth is fast, and per mu yield is high, soft and succulency, and palatability is fine, and utilization rate is high, and the eatings such as ox, horse, sheep, rabbit, duck, goose are deeply by the herbage variety that cattle and sheep raiser likes.But herbage water content is high, the easy moldy metamorphism of storage process.And roasting, the solarizations of routine etc. are removed, and the method energy consumption of moisture content is high, labour intensity is large.
Summary of the invention
The object of the invention is open a kind of biological feedstuff production method, is the production method utilizing cassava stalk, manioc waste and grass industry stocker feed, can improve the palatability of raw material, improve digestibility, and can long term storage and corruption of not going mouldy.
Technical scheme of the present invention is:
The production method of cassava stalk, manioc waste and grass industry stocker feed, comprises the steps:
(1) cassava stalk, manioc waste and herbage pulverizer are pulverized, and cross screen cloth, get the particle between 2 ~ 10 orders;
(2) particle obtained above adds the urea of its weight 1%, mixes, and then uses 120 ~ 125 DEG C of steam treatment 30 ~ 60min, is cooled to less than 30 DEG C, add Trichoderma viride liquid medium, cultivates 24 ~ 48h;
(3) material that step (2) obtains adds the mould liquid medium of healthy and free from worry wood, cultivates 24 ~ 48h;
(4) material that step (3) obtains adds lactic acid bacteria liquid medium, seals at least 7 days, obtains stocker biological feedstuff.
The production method of described Trichoderma viride liquid medium: every 1 liter of potato extract adds glucose 20g, potassium dihydrogen phosphate 2g and ammonium sulfate 5g, access Trichoderma viride bacterial classification (Classification system Trichodermaviride) after conventional sterilant, 16h cultivated by shaking table; Described potato extract: get peeled potatoes 200g, be cut into small pieces, the 1.0L that adds water boils 30min, and elimination potato ball, complements to 1.0L by filtrate.Trichoderma viride belongs to Deuteromycotina, Hyphomycetes, hyphomycetales, and sticky spore mushroom is the ubiquitous fungi of a class, and Trichoderma viride is one of institute's cellulase-producing the highest active bacterial strain, and the cellulase produced has degradation to crop, and effect is very good.
The production method of the described mould liquid medium of healthy and free from worry wood: every 1 liter of potato extract adds glucose 20g, potassium dihydrogen phosphate 2g and ammonium sulfate 5g, access healthy and free from worry Trichoderma kind (Classification system TrichodermaKoningii) after conventional sterilant, 16h cultivated by shaking table; Described potato extract: get peeled potatoes 200g, be cut into small pieces, the 1.0L that adds water boils 30min, and elimination potato ball, complements to 1.0L by filtrate.Healthy and free from worry Trichoderma has very strong cellulose mycophenolate and fiber, two saccharogenic amylases, lignoenzyme etc., and it can be beneficial to agricultural byproducts, and as straw, timber, the cellulosic materials such as wood chip, make it to change saccharine material into.
The production method of described lactic acid bacteria liquid medium: every 1 liter of distilled water adds peptone 5.0g, beef extract 10g, yeast extract 5.0g, glucose 10.0g and NaCl5.0g, access lactic acid bacteria culturers (Classification system LactococcusLactis) after conventional sterilant, 16h cultivated by shaking table.Lactic acid bacteria can produce a large amount of lactic acid from fermentability carbohydrate, and the lactic acid of generation can suppress the growth of other miscellaneous bacterias, thus the shelf-life of food and extend.
The good effect that the present invention produces is: the effect utilizing multiple-microorganism, cellulose in degraded cassava stalk, manioc waste and herbage and lignin, make the feed made soft, improve palatability, improve digestibility, and by the fermentation of lactic acid bacteria, increase the fragrance of feed, and can long term storage feed, prevent feed mold.
