The product of the invention has the advantages of accelerating the silage acidification process, shortening the silage period, preventing the problems of poor fermentation and secondary fermentation of silage after opening the cellar, preserving silage nutrients to the maximum extent, improving the digestibility and improving the quality of the silage, and further promoting the improvement of milk yield of dairy cows and the fattening performance of beef cattle and mutton sheep.
Description
Technical field
The present invention relates to a kind of feed combined acidity conditioning agent, particularly disclose a kind of ensilage with combined acidity conditioning agent and using method thereof, belong to feed additive field.Preparation of the present invention can be used as silage additive and uses, can make ensilage not be subjected to the impact of type of feed, weather conditions, moisture content of raw material etc., have the ensiling of acceleration acidization and shorten the ensiling cycle, prevent the secondary fermentation problem after bad fermentation and ensilage are opened the cellar for storing things, preserve to greatest extent the ensilage nutriment, improve digestibility and improve the ensilage quality, and then promote the raising of milk production of cow and promote the finishing ability of beef cattle, mutton sheep.
Background technology
Successfully modulating high-quality and stable all kinds of herbages and cereal ensilage, is the decisive prerequisite that milk cow, beef cattle, mutton sheep aquaculture, dairy industry and animal husbandry are enhanced competitiveness.Although Sativa Silage Technology has had huge advance made at present, but still have the secondary fermentation problem after always also having bad fermentation and open the cellar for storing things in about 1/3rd all kinds of herbages and the cereal ensiling, these bad fermentations and secondary fermentation greatly reduce the feed value of ensiling, animal feed intake is reduced, the basal feed production capacity descends, and all kinds of mycotoxins that secondary fermentation produces also can cause potential security threat to human health by food chain.In addition, though tradition Silaging method or to add merely the lactobacillus preparation ensiling effective to the high raw material of solubility sugar content, and can't realize effective ensiling to all kinds of herbages and the cereal of low solubility sugar content and high protein because of its stronger buffer capacity, although artificially can effectively guarantee in theory the ensiling modulated process of low solubility sugar content and high protein raw material by the mode of mending pure interpolation molasses, but the situation of reality is the expection of the non-theory of additive effect of molasses, practical application is but effectively verified, and the interpolation of molasses not only needs high cost, in addition also comparatively inconvenience of its production operation needs extraordinary operating equipment and special expense expenditure.
Present stage all kinds of herbages and cereal ensilage Main Problems comprise following several aspect:
(1) the bad fermentation problem of herbage and cereal ensiling
The ensilage of all kinds of herbages and cereal is owing to being subjected to the wherein impact of butyric acid and the bad fermentation of butyric acid to pollute with the phenomenon of clostridial toxin very general, during ensiling, this bad fermentation is difficult to avoid the herbage that particularly sugar content is lower (such as alfalfa, Bai Sanye, rye grass etc.) in the higher situation of humidity.Owing to be subjected to soil pollution or be entrained with withered plant component, it is larger that clostridium enters the possibility of making raw material, and then the risk of this bad fermentation is higher.Clostridium can produce endospore through still in vivo survival behind the milk cow digestive system, and excretes by ight soil and to come back to the field.Constantly propagate whereby and circular regeneration.Shuttle shape gemma has the protection heavy wall, has heat-resisting, cold-resistant and chemically-resistant thing characteristic, can survive under adverse circumstances, and suitably germinate and continuation breeding growth under the environment.The ability tanacity because clostridium lives again, milk is infected after milking in (Room) even the picked-up of a small amount of dirt also is transferred to cow breast, causing lactation.Thereby cause the variety of issue in the processing of milk and dairy products.Because the clostridium route of transmission at first is to enter in the Contents in Cows through the grass silage material, so from start with at all, the measure that improves the ensilage health is indispensable.
(2) ensilage is opened the secondary fermentation problem behind the cellar for storing things
Successful silage fermentation can keep enough stability after opening the cellar for storing things, even serious heat production phenomenon does not occur yet in excess Temperature ensilage inside.The situation of reality is for owing to not having interpolation or only adding the ensilage that simplicity microorganism ensiling agent reduces pH-value rapidly, has the problem that can keep the stable acetic acid of ensiling to lack.Although such ensiling is well fermented, but may generate heat rapidly owing to entering heavily again of air after opening the cellar for storing things, if particularly have in the whole cellar for storing things residual " air-bed " (usually since shed inhomogeneous, prescind not or compacting not tight), air can take advantage of the occasion to invade, the harmfulness saccharomycete is bred rapidly, its aerobic respiration decomposing lactic acid, and the pH value raises heavily again in the ensiling container, mycotic spore begins rudiment, thus the ensilage moldy metamorphism.If in conjunction with slower feeding speed, lasting high temperature, a large amount of nutrient losss, the discarded waste of feed and the low-quality of feed then are inevitable.If highly polluted ensilage is then more dangerous as the mixing companion of complete mixed daily ration TMR, because it can be diffused into saccharomycete and mould in all the other mixed feeds again in mixing very soon.
(3) add merely the limitation of lactobacillus preparation ensiling
Though adding, lactobacillus preparation is the ensilage modulation, especially high to solubility sugar sugar content crop ensiling (such as corn etc.) provides the lactic acid bacteria that occupies predominance, and promote fermentation and acid and reduce rapidly ensilage pH, the risk that effectively stops bad fermentation, but all kinds of ensilages lack screening system and seed selection with the lactobacillus preparation bacterial classification in the market, bacterial classification is relatively backward, it is limited to produce acid and acid resistance, resistance is looked into, unstable properties, to low solubility sugar content, all kinds of herbages such as the alfalfa that are difficult for ensiling of high protein, Bai Sanye, the ensilings such as rye grass can't realize successfully modulating, and the poor stability behind the Yin Qikai cellar for storing things, especially can't effectively avoid the secondary fermentation problem of ensilage at high temperature season.
(4) herbage and cereal add the limitation of molasses ensiling
Ensilage artificially adds the non-theoretical expection of actual effect of molasses, has following limitation or problem:
1, the extra molasses that add have been proved to be intimate invalid in the ensilage.Because molasses also are of value to the breeding of the harmful bacteria that ferments, can excite butyric acid fermentation and cause fermentation bad.Simultaneously, molasses also can make ensilage " inoculation " infection saccharomycete, mould etc. cause secondary fermentation, and silage fermentation is caused negative effect;
2, the monose that contains in the molasses and disaccharide be not whole decomposition and inversion be lactic acid, add molasses and do not increase the ensiling energy content;
3, the theoretical addition of molasses is about ensilage 30kg per ton.Therefore, its interpolation is with high costs;
4, the dosage apparatus of molasses interpolation is complicated, costly, and the operation process sanitary condition is not good enough after molasses adding procedure and the interpolation.
(5) the domestic ensilage development and utilization situation of acidity regulator
Ensilage need be considered many complicated factors such as moisture characteristics (general 65-70%), type of feed (solubility sugar content, cushion effect etc.), weather conditions of ensiling raw material with acidity regulator exploitation, Current Domestic is almost developed without system research.Collaborative composite by between the organic acid such as propionic acid, formic acid, Sodium Benzoate and the salt thereof of the present invention, a kind of ensilage combined acidity conditioning agent that provides in conjunction with special processing technology, can effectively overcome all kinds of problems that exist in the above-mentioned present ensiling modulated process, make ensilage not be subjected to the impact of type of feed, weather conditions, moisture content of raw material etc., have the ensiling of acceleration acidization and shorten the ensiling cycle, avoid bad fermentation and the secondary fermentation problem of ensilage, guarantee fine quality and the aerobic stability of ensilage; In addition, can effectively solve the ensiling modulation difficult problem of low solubility sugar, high protein ensiling raw material (cushion effect is strong), and then promote the raising of milk production of cow and promote the finishing ability of beef cattle, mutton sheep, the economic benefit of promoting livestock-raising.
Summary of the invention
