Abstract
The invention relates to a method for ensiling half-dry alfalfa. The method comprises the following steps of: firstly, clipping alfalfa growing to the initial flowering period in due time, airing the alfalfa until the moisture becomes 45-55%, chopping, loading the chopped alfalfa into an ensiling pool, compacting the alfalfa, sealing the top by using a plastic film and soil successively after filing the ensiling pool, and storing the alfalfa for 50-60 days to feed. With the alfalfa half-dry ensiling method, the loss of pasture nutrition constituents is furthest reduced, the quality of the alfalfa is improved, the method is easy and convenient to operate and has low cost, and the supply of fresh alfalfa all the year around is realized. The half-dry ensiled alfalfa produced by the method is fresh, tender and juicy and has good palatability and high digestion rate, the traditional understanding that the fresh alfalfa is difficult to independently prepare an ensiled feed is broken through, and a reliable basis is provided for reasonably utilizing and storing alfalfa and popularizing the alfalfa half-dry ensiling technology in large area.
Description
Technical field
The present invention relates to animal forage grass technical field, particularly relate to a kind of alfalfa haylage method.
Background technology
Clover is perennial leguminous forage, have be of high nutritive value, advantages such as good palatability, period of use are long, plantation wide adaptability, have the laudatory title of " king of herbage ", be the high quality forage of development of modern animal husbandry.I distinguish clover and stay long-pending 6,000,000 mu of bed surface, mainly concentrate on southern mountain area.The method of traditional results and storage clover mainly is a hay curing.The restriction short because of clover harvest time, that lignifying speed is fast, the modulation green hay receives weather conditions such as overcast and rainy easily; In harvesting, shine in the link such as make, store, transport, feed and often cause the loss of a large amount of cauline leafs; Cause the bright clover of ratio of crude protein to reduce more than 5 percentage points, vitamin with can digest crude fibre and also reduce greatly.Therefore, how reasonable processing is modulated clover, at utmost preserves the nutritional labeling of clover, and I distinguish forage grass processing and utilization level to have become lifting, promote the task of top priority of careless animal industry sustained and rapid development.
Summary of the invention
The object of the present invention is to provide the alfalfa haylage method of a kind of effective preservation clover nutritional labeling, raising clover quality and value.
For realizing that the technical scheme that the foregoing invention purpose is taked is:
A kind of alfalfa haylage method; Its processing step is: the clover to growing into initial bloom stage cradles in good time; Airing to moisture reaches 45%～55% back chopping, the ensiling pond of packing into, compacting; Wait to fill up behind the ensiling pond successively with plastic sheeting and tight the binding of soil, can be feeding after storage in 50 days～60 days;
Avoid being exposed to the sun in the above-mentioned airing process;
Above-mentioned chopping length is 2cm～5cm;
The good clover of the above-mentioned chopping ensiling pond of must packing into the same day;
The clover that above-mentioned chopping is good can add ensiling modulation additive before the ensiling pond of packing into; Described additive has lactic acid bacteria, organic acid or glucose; Wherein every 1000kg clover adds the 2.5g lactobacillus preparation; Every 1000kg clover is added 2kg～4kg organic acid, and every 1000kg clover adds 10kg～15kg glucose;
When filling up the ensiling pond, the raw material that above-mentioned chopping is good requires to exceed ensiling pond upper edge 30cm～40cm;
Above-mentionedly be meant that being covered with plastic sheeting earlier obturages, and then earthing 20cm～30cm with plastic sheeting and tight the binding of soil;
To observe at any time in 2 days～3 days after above-mentioned tight the binding, and find that raw material sinks, and banketed in sinking place.
The present invention has following technical advantage:
1, the present invention can realize in good time, concentrate results, reduces the nutritional components loss to greatest extent, improves the clover quality;
2, easy and simple to handle, cost is low, it is little to take up an area of the space, can year-round provision;
3, the fresh and tender succulence of alfalfa haylage of the present invention, good palatability, digestibility is high, has broken through the traditional understanding that bright clover grass is difficult to modulate separately ensilage, and for rationally utilizing and store clover, large tracts of land is promoted the alfalfa haylage technology reliable basis is provided.
Following table is an alfalfa haylage effect comparison table:
Feed beef cattle test of alfalfa haylage:
Test method: select 18 of body weight (375 ± 30) kg, agematched west door tal fibre Hybrid finished cattles, be divided into two groups at random, be divided into alfalfa hay group, alfalfa haylage group according to the roughage difference of feeding, feeding and management condition is consistent, 90 days experimental periods.
Result of the test: head all adds up weightening finish and daily gain, and the alfalfa haylage group utmost point is significantly higher than alfalfa hay group (P＜0.01).In 90 days of experimental period, the alfalfa haylage group is all Duoed weightening finish 26.25kg than alfalfa hay group head, and average daily gain increases 291.7g, improves 32.76%, 663.84 yuan of all newly-increased net incomes of head.
The specific embodiment
Alfalfa haylage method of the present invention is specially:
1, the in good time results of clover
Cradle during at alfalfa growing to initial bloom stage (20% blooms) in good time; Carry out after cradling airing (under the fine situation of weather, the clover airing of generally plantation 12 hours～24 hours, arid area airing 8 hours～12 hours in the irrigated area; Airing to blade is fading not roll up and is got final product; Prevent to be exposed to the sun), when moisture reached 45%～55%, the feedstock delivery that airing is good was made the place to ensiling.
2, chopping and compacting
Raw material is in time shredded with hay cutter, generally be cut into 2cm～5cm and be advisable, raw material after the chopping ensiling pond of must packing into the same day.For pH value, the quantity of replenishing nutritional labeling not enough in the alfalfa ensilage raw material, increase lactic acid bacteria original state that reduces the alfalfa ensilage raw material, the palatability of improving the alfalfa ensilage feed; Before the dress pond, the raw material of additive and chopping mixed and adorn the pond then, as: lactic acid bacteria (every 1000kg clover adds the 2.5g lactobacillus preparation), organic acid (every 1000kg clover is added 2kg～4kg organic acid) or glucose (every 1000kg clover adding 10kg～15kg glucose) etc.The clover raw material that is mixed with additive wants the limit to cut up with a hay cutter dress pond, broken limit, limit dress pool side compacting, and the raw material of as far as possible avoiding shredding was exposed to the sun of a specified duration outside the pond.Will successively carry out compacting, can adopt manual work to tread layer by layer during small-scale operations, every dress 30cm～50cm treads once, will notice that especially the corner tramples, and does not preferably stay the slit.The Da Chi ensiling generally adopts large tractor or four-wheel tractor to carry out compacting, and artificial having peace of mind or mechanical ramming are adopted in the corner, pond.After raw material is filled, exceed about the upper edge 30cm～40cm of ensiling pond, to guarantee that the back is air tight or to prevent to infilter rainwater.
3, sealing
After raw material fills up compacting, be covered with layer of plastic film and obturage, again earthing 20cm～30cm.To observe at any time after binding 2 days～3 days, find that raw material sinks, should banket, prevent that air and rainwater from getting at the place of sinking.
4, preserve
Alfalfa haylage generally can be opened use after 50 days～60 days.
