Background technique
Since 21 century, China's animal husbandry development is rapid, and feed increases year by year as the basal needs amount of animal husbandry development.
However, the shortage problem of feedstuff always affects the development of animal husbandry, become a major challenge that China's animal husbandry faces.South
The important area that the China Fang Zuowei develops animal husbandry is abundant with hydrothermal resources, and growing season of grass is long, the production of unit area meadow
The high inherent advantage of power, but still the problems such as that there are forage grass utilization rates is low, and production technology and management mode fall behind, restricts herding
Industry development.Wherein feed season, which supplies unbalanced problem, becomes an important factor for restrict south China animal husbandry development.By
In south China wet weather high humidity weather conditions, hay curing be it is difficult to realize, herbage is modulated into ensilage can be maximum
The reservation nutriment of limit is the ideal method for solving feed season supply imbalance problem.
Herbage moisture general control is easy successfully to modulate quality silage 65%~75%.If after herbage cradles
Direct ensiling leads to the failure because of high (80%~90%) the Yi Yinqi butyric acid fermentation of water content, and nutriment is lost seriously, agreeable to the taste
Property seriously reduces.And the season exactly plum rain season that southern herbage cradles, it is difficult to dry it or wither here to handle.
In the prior art, the research of Silage Quality is generally improved by addition lactic acid bacteria, but lactic acid bacteria addition can be with
Can the microorganism competition of herbage surface attachment, it is unstable to obtain quality silage effect after inoculation.Therefore it is herded according to south
Careless water content is high, harvest season rainy the problems such as being not easy ensiling and avoiding lactic bacteria additive effect unstable, it is necessary to develop
A kind of compound additive of suitable high-moisture Silage.

Technical solution provided by the invention is described in detail below with reference to embodiment, but they cannot be understood
For limiting the scope of the present invention.
A kind of compound additive for being used to prepare high-moisture ensilage of embodiment 1
1) 495kg propionic acid is poured into reaction kettle, 244kg formic acid is added in reaction kettle and with the stirring of 20 hertz of frequency
Uniformly；
2) 47kg solid potassium sorbate is dissolved in 175kg water, until being completely dissolved；
3) dissolved potassium sorbate solution and 39kg propylene glycol are incorporated in reaction kettle and are stirred evenly, obtain compound add
Add agent；
4) 25 DEG C are down to product temperature to be packed；
Reaction temperature control is at 30 DEG C in preparation process.
Influence of the compound additive of the present invention of embodiment 2 to grass silage feed fermentation quality
Ensiling production is carried out without wilting after the clover of flowering stage is gathered in.By the clover of harvest, (clover moisture contains
Amount is 83.5%) chopping to 1~2cm；What test group addition embodiment 1 was prepared is used to prepare answering for high-moisture ensilage
Close additive, additive amount 4ml/kg；Blank control group adds the distilled water of same volume.Three repetitions of each processing, Mei Gechong
Multiple 300g is loaded in polyethylene vacuum packaging bag and vacuumizes.The ensiling 60 days under the conditions of 25 DEG C.To obtained ensilage
Indices are detected, as a result referring to table 1.
Influence of the compound additive of the present invention of table 1 to grass silage feed fermentation quality
Note: the different letter of data of going together in table indicates significant difference (P<0.05), same letter indicate difference it is not significant (P>
0.05)。
As can be seen from Table 1, adding compound additive of the present invention can significantly reduce ensilage pH, reduce dry matter damage
Lose, reduce ensilage ammonia nitrogen content, increase lactic acid and yield of acetic acid (P < 0.05), clostridium in sample after ensiling, yeast and
Mould quantity, which is substantially less than, to be compareed.It can be seen that compound additive of the invention inhibits ensiling harmful bacteria significant effect, energy
Significantly improve high-moisture grass silage feed quality.
Embodiment 3 compare different ratio compound additive to high-moisture Itanlian rye silage fermentation quality and saccharomycete and
The inhibiting effect of mould
Test proportion is referring to table 2.
2 different ratio of table handles table
Note: formic acid and propionic acid used are chemical reagent, are analyzed pure.Potassium sorbate.Food antiseptic preparation.At each ingredient
Reason is based on 100g.
The Itanlian rye (water content 80% or so) of fresh harvest is shredded to 1~2cm, the addition of different ratio is added
For agent 4ml/kg in fresh grass, control group adds the distilled water of same volume.500g is added to the uniformly mixed fresh grass dress of additive
In polyethylene vacuum packaging bag and vacuumize.The ensiling 60 days under the conditions of 25 DEG C.3 repetitions of each processing.It is formulated by 4
To the inhibiting effect of high-moisture Itanlian rye silage fermentation quality and aerobic bacteria, the optimal high-moisture ensiling antistaling agent of screening is matched
To clostridium in high water Itanlian rye silage fermentation quality and ensilage, the influence of saccharomycete and mould quantity is shown in Table 3 for side.
Shadow of the 3 high-moisture ensiling anti-mould fresh keeping agent of table to high-moisture Itanlian rye ensilage fermentation quality and microorganism
It rings
By comprehensive different ratio to Silage Quality and the microbiological effect ratio of Itanlian rye it is found that experimental group 1 is matched
Itanlian rye ensiling pH can be significantly reduced, more lactic acid and acetic acid are generated, can preferably inhibit the harmful bacterias such as clostridium.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
