Description
Technical field
The present invention relates to feed production method, particularly relate to the manufacture method of a kind of Boehmeria and whole-plant corn mixed silage feedstuff.
Background technology
Ensilage be by green forage through chopping and by water content control between 65% ~ 75%, under conditions of airtight anoxia, carrying out anaerobic fermentation to make, its production principle is promotion lactic acid bacteria amount reproduction in anaerobic environment, makes solubility sugar be converted into lactic acid and accumulate to finite concentration；Lactic acid bacteria fermentation produces a large amount of lactic acid after decomposing saccharide, and the lactic acid of generation makes feedstuff be faintly acid (pH value 3.5-4.2), can effectively suppress other growth of microorganism, thus effectively suppress putrefaction bacteria so that the nutrient substance in ensilage is preserved for a long time.Ensilage has that abnormal smells from the patient acid perfume, soft and succulency, quality be soft, good palatability, nutritious, be beneficial to long-term preservation, be the excellent food source of the phytophage domestic animal such as cattle, sheep, be also to solve one of main method lacking fresh herbage winter in Livestock Production.
At present, major part ensilage is to use agricultural crop straw or feeding sugar grass, ensiling special corn etc., directly prescinds, is compacted, seals and produce.Owing to the nutrient composition content of raw material own is the lowest, particularly crude protein and solubility carbohydrate content is the lowest, simultaneously farming straw self with lactic acid bacterium number limited, it is difficult to quickly form lactate fermentation, make the putrefaction bacteria activity time long, the pH of ensilage declines slowly, causes ensilage nutritive loss excessive, easily causes ensilage corrupt.For improving ensilage quality, increase the utilization ratio of the non-graminous pasture of good quality and high output, change people's understanding to conventional silage making, particularly be it is believed that being difficult to the successful herbage of ensiling is processed ensiling, the waste material produced in commercial production or food processing and bran is utilized to carry out fermentable, the method carrying out mixed silage again with the herbage being difficult to independent ensiling solves to be difficult to the successful difficult problem of ensiling, to greatly improve ensilage quality.Therefore, the quality improving ensilage is to promoting animal husbandry health, quick, stable development, social materials supply and resources conservation, all having great importance and be worth.
A kind of ensilage processing technique as disclosed in CN103504124A, is by the corn straw whole strain collection of 7-10 day after dough stage, the whole strain corn straw smashing that will gather, it is cut into 1-3cm length thread, before putting into pit, sweep pit, pit ground, wall paving plastic foil, then raw material is piled with pit, and often stack 50cm thickness to compress once, finally in top salting 2-4cm, lid two membranes, with sandbag, difference thin film stitching portion is compacted, after fermentation 25-50 day, obtains ensilage.The deficiency of this technical scheme is, in ensilage, crude protein content is on the low side, and the loss of sweat Middle nutrition is the most serious.
And for example a kind of silage preparation process disclosed in CN101849626A, is to be collected by plant stalk；Collected plant stalk pulverizer is pulverized；Plant stalk after being pulverized adds strain and other dispensing is fermented；Bailing, sealing；Wherein, described plant stalk is blue or green rice Fructus Citri tangerinae bar, and the strain of interpolation is lactic acid bacteria, and dispensing is corn stalk powder, wheat bran, and fermentation temperature is room temperature, and fermentation time controlled in 1-2 day.The deficiency of this technical scheme is, strain large usage quantity, and Silage Quality is poor, less economical, is unsuitable for promoting the use of.
Summary of the invention
It is an object of the invention to be difficult to successfully for the single ensiling of non-graminous pasture in solution prior art, in food processing Glycine max (L.) Merr. be difficult to store utilization rate low, ensilage crude protein content is too low, the problems such as Silage Quality is poor, it is provided that a kind of Boehmeria and the manufacture method of whole-plant corn mixed silage feedstuff.
The present invention is achieved through the following technical solutions its purpose:
The present invention is the manufacture method of a kind of Boehmeria and whole-plant corn mixed silage feedstuff, it comprises the steps: to gather in fresh Boehmeria and whole-plant corn, fully mix after being mixed in proportion and add microbe leaven after tiling dry in the sun rear cutout being broken, then the product being uniformly mixed so as to obtain is packed in silage silo compacting, and covered with plastic film, i.e. obtain ensilage after overlying soil is obturaged on a plastic film after sealing and fermenting 20-30 days.
Wherein, microbe leaven addition in the mixture of Boehmeria and whole-plant corn is 0.4g/kg.The mixture of the most every kg Boehmeria and whole-plant corn adds 0.4g microbe leaven.
Preferably, harvesting Boehmeria is 10cm with the whole-plant corn height for the stubble left, and all gathers at fine day.Boehmeria plant height is preferably 60
Cm between ~ 80, the plant between whole-plant corn preferably selection milk stage to stage of wax ripeness.
Preferably, Boehmeria mixes for 1:1 in mass ratio with whole-plant corn.And this component approximately equal, therefore, also it is feasible by mass ratios such as 2:3,3:4,5:4.
Preferably, Boehmeria and whole-plant corn dry in the sun time are 0.5h ~ 2h, and dry in the sun to water content drops between 65% ~ 75%, shreds immediately after.
Preferably, successively insert when the product being uniformly mixed so as to obtain is packed in silage silo, every thickness 20cm ~ 30cm, successively manually track tramping with mechanical ramming or employing, after silage silo is filled, with covered rearing with plastic film, above plastic sheeting, cladding thickness is about 30cm soil layer, silage silo surrounding is tight with grave, prevent gas leakage of leaking.
Compared with prior art, production method that what the present invention reached have the beneficial effect that is simple and easy to do, low cost, crude protein content height, quality better, practical；The ensilage prepared is yellow green, abnormal smells from the patient acid is fragrant, quality is soft, without perverse nose abnormal smells from the patient, stem and leaf keeps state before ensiling, and vein is high-visible；Good palatability, the lactic acid content in ensilage (fresh sample) reaches 8mg/kg, and pH value is between 3.5 ~ 3.7, and crude protein content is 11.43%；Fermentation time is shortened while improving ensilage quality.
The present invention uses Urticaceae herbage Boehmeria to add microbe leaven, sealing and fermenting after mixing in proportion after shredding with graminous pasture whole-plant corn, be conducive to making lactic acid bacteria rapidly become dominant bacteria, accelerate the pH decrease speed of ensilage, also can reduce the nutrient loss of ensilage, improve ensilage quality, there is the advantages such as with low cost, convenience and high-efficiency, good economy performance, for improving the ensilage present situation of vast livestock-raising peasant household, have great practical value and economic implications.Use the addition of mixed proportion of the present invention and microbe leaven, the content of crude protein in ensilage can be improved in amplitude, shorten fermentation time, beneficially ensilage and store (2 years can be preserved) for a long time.
The present invention use microbe leaven as lactic acid bacteria, organic acid source, by microbe leaven with shred the two kinds of herbage uniform mixture manufacturing ensilages mixed in proportion.Owing to microbe leaven containing substantial amounts of lactic acid bacteria and organic acid, it is added to shred in mixed herbage, the lactic acid bacterium number in mixing herbage can be made to improve rapidly, become dominant bacteria；Organic acid makes the pH value of herbage to be store decline, and creates and is more suitable for the environment that lactic acid bacteria is movable, so that ensilage quickly forms lactic acid bacteria fermentation, the growth of suppression putrefaction bacteria, and then improves the quality of ensilage.Physiology phase when the invention provides the ensiling of whole-plant corn loads thickness, the thickness etc. of overlying soil with the ensiling height of Boehmeria, the mixed proportion of two kinds of herbages, the adding proportion of microbe leaven, fermentation time, silage silo.These parameters are the synthesis result that inventor produced, observed, repeatedly studies discovery through long-term practice, and have been experimentally verified that its feasibility and correctness, are non-obvious.
Ensilage of the prior art is usually the straw ensiling of single gramineous crop or graminous pasture and leguminous forage mixed silage, and the silage fermentation time is 40-50, just can open cellar for storing things (pond) use.The present invention utilizes the Urticaceae herbage Semen Sesami and whole-plant corn mixed silage that crude protein content is higher, improves the content of crude protein in ensilage, and adds interpolation microbe leaven in ensiling, shorten fermentation time, minimum only needing 25 days, and nutrient loss is little, ferment effect is good.Ensilage that the present invention prepares preserves the time limit up to 2 years or longer, thus can make up the deficiency that greenfeed crude protein content is too low, accomplishes the annual stable market supply of nutrient substance.After fermentation ends, the pond time of opening of ensilage as required depending on, avoid high temperature or severe cold season as far as possible.Because high temperature easily makes ensilage ferment in second time or stiff rotten, severe cold easily causes ensilage to freeze.
The present invention by the water content control of ensiling raw material at 65%-75% because moisture is too low or too high the most unfavorable.Water deficient in raw material, is difficult to compacting, keeps air, cause moldy metamorphism.Excess moisture in raw material, soluble nutrient easily runs off with the juice oozed out, and sugar content is relatively low simultaneously, is easily caused putrefaction bacteria amount reproduction, affects the quality of ensilage.Sugar is the raw material that lactic acid bacteria fermentation forms lactic acid, the most sufficient amount of sugar, its is possible to make lactic acid bacteria produce sufficient amount of lactic acid, the 1.5% of the most preferably less than its fresh weight of the sugar content in ensiling raw material.Ensilage must create anaerobic environment early by modes such as compacting, sealings, create conditions for lactic acid bacteria fermentation.Whole-plant corn is smashed with Boehmeria and is mixed by the present invention in proportion, and adds microbe leaven, can sufficiently promote fermentation, it is ensured that the effect of fermentation, improves crude protein content in ensilage.
When selecting ensiling raw material, it is preferably selected the ensiling raw material that sugar content is high, moisture content is suitable.Herbage of the present invention selects the whole-plant corn of grass family dough stage and the Boehmeria of Urticaceae plant a height of (60cm ~ 80cm).This is because the content (at least the 1.5% of fresh weight) of ease of solubility carbohydrate is to ensure that lactic acid bacteria amount reproduction in ensiling raw material, form the primary condition of enough lactic acid, Boehmeria crude protein content when plant a height of (60cm ~ 80cm) is higher, the protein content in ensilage can be improved, improve Silage Quality.
In the present invention, the ensiling time can select to gather in fresh herbage at fine day, is not only due to beneficially dry in the sun and controls water content, reducing the adverse effect factor in environment, it is to avoid herbage goes bad；Also it is because raw material must gather in good time can ensure that Feed Manufacturing can obtain most nutrient substance.Too early, raw aqueous is many, can digest nutrient substance few in harvesting；Too late, content of cellulose increases, and palatability is poor in harvesting, and digestibility reduces.Ensiling feed moisture content of the prior art and harvesting weather are without necessary connection, and therefore the present invention selects to obtain optimum efficiency in fine day harvesting is not obvious.This is also likely to be owing to fine day environment constitutes, to the nutrition in herbage, the Micro influence that generation is useful.
PH value is one of important indicator weighing ensilage quality quality.Excellent ensilage pH is below 4.0.Use ensilage pH=3.5 ~ 4.0 that the present invention prepares, for colory ensilage, its Main Nutrient Quality is close with its ensiling raw material, nutritive loss is little, there is good palatability, feed intake, organic matter digestibility and effective energy value corresponding to ruminant are all similar to ensiling raw material, and nutritional quality is good.
