Description
Technical field
The present invention relates to feed production method, particularly relate to the production method of a kind of Boehmeria and prestige peaceful hardinggrass 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 what anaerobic fermentation was made, 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 abnormal smells from the patient acid perfume, soft and succulency, good palatability, preservation nutritious, the most long-term, is the excellent food source of Herbivore domestic animal, is also to solve one of main method lacking fresh herbage winter in Animal husbandry 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 seasonality and the nutrient composition content of raw material own of crop growth are the lowest, particularly crude protein and solubility carbohydrate content is the lowest, farming straw self with lactic acid bacterium number limited, it is difficult to quickly form lactate fermentation, making the putrefaction bacteria activity time long, the pH of ensilage declines slowly, causes ensilage nutritive loss excessive, easily causing ensilage corrupt, the popularization of serious restriction ensilage expands use.For promoting the use dynamics expanding ensilage and improving ensilage quality, Urticaceae herbage higher to the graminous pasture of high yield and high quality and protein content is carried out mixed silage, with the Use Limitation reaching extension ensilage and the crude protein content improved in ensiling, adding microbe leaven in ensilage is to allow lactic acid bacteria rapidly become dominant bacteria, accelerate the pH decrease speed of ensilage, reduce the nutrient loss of ensilage, microbe leaven is added in ensilage, the additives such as organic acid also achieve good effect, substantially increase 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 production method of prestige peaceful hardinggrass mixed silage feedstuff.
The present invention is achieved through the following technical solutions its purpose:
The present invention is the production method of such a Boehmeria and prestige peaceful hardinggrass mixed silage feedstuff, it comprises the steps: to gather in fresh Boehmeria and Wei Ning hardinggrass, 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 Wei Ning hardinggrass is 0.4g/kg.The mixture of the most every kg Boehmeria and Wei Ning hardinggrass adds 0.4g microbe leaven.
Preferably Boehmeria selects the plant between the high 60 ~ 80cm of plant, and the peaceful hardinggrass of prestige gathers in before heading.All harvestings are all carried out at fine day.The harvesting Boehmeria height for the stubble left is 10cm；The harvesting prestige peaceful hardinggrass height for the stubble left is 5cm.
Preferably, microbe leaven is added for 1:1 after Boehmeria hardinggrass peaceful with prestige mixes in mass ratio.And the two mixed components approximately equal, therefore, Boehmeria and the peaceful hardinggrass of prestige are also feasible by mass ratios such as 2:3,3:4,5:4.
Preferably, Boehmeria and Wei Ning hardinggrass dry in the sun time are 0.5h ~ 2h, and dry in the sun to water content drops between 65% ~ 75%, shreds immediately after.
Additionally, should successively insert when the product being uniformly mixed so as to obtain is packed in silage silo, every thickness 25cm ~ 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 3.63mg/kg, and pH value is between 3.8 ~ 4.1, and crude protein content is 7.57%；Fermentation time is shortened while improving ensilage quality.
The present invention adds microbe leaven, sealing and fermenting after mixing in proportion after using the chopping of Urticaceae herbage Boehmeria hardinggrass peaceful with graminous pasture prestige, be conducive to making lactic acid bacteria rapidly become dominant bacteria, accelerate the pH decrease speed of ensilage, 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 increased substantially, shorten fermentation time, beneficially ensilage and store (2 years can be preserved) for a long time.
The present invention use microbe leaven as originating in lactic acid bacterium, 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 the peaceful hardinggrass of prestige 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, the silage fermentation time is more than 40-50 days, just can open cellar for storing things (pond) to use, and the making of ensilage was limited by crop growing season.The present invention utilizes the Urticaceae herbage Boehmeria and prestige peaceful hardinggrass mixed silage that crude protein content is higher, improve the content of crude protein in ensilage, and add in ensiling interpolation microbe leaven, shorten fermentation time, minimum only need 20 days, nutrient loss is little, ferment effect is good, and Boehmeria and the peaceful hardinggrass of prestige are high yield herbage, can cradle every year more than 6 times, therefore, Boehmeria hardinggrass peaceful with prestige mixed silage can be carried out in any time section in addition to winter.Ensilage that the present invention prepares preserves the time limit up to 2 years or longer, can make up the deficiency that in green grass or young crops feedstuff, crude protein content is too low, accomplish the annual stable market supply of nutrient substance.
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.Peaceful to Boehmeria and prestige hardinggrass is smashed 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 ensilage quality.
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 Boehmeria of the peaceful hardinggrass of grass family prestige (before heading) and Urticaceae plant a height of (60cm ~ 80cm).This is because the rich content (at least the 1.5% of fresh weight) of prestige peaceful hardinggrass (before heading) the ease of solubility carbohydrate in ensiling raw material is to ensure that lactic acid bacteria amount reproduction, 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 as raw material must gather in and can ensure that and can obtain most nutrient substance in Feed Manufacturing in good time.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=3.8 ~ 4.1 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.
