Abstract
The present invention provides a technology for producing a mixed fermentation feed by using a food processing by-product corn steep liquor and rice straw through adding a lactic acid bacteria preparation, wherein the selected lactic acid bacteria preparation is prepared through compounding three lactic acid bacteria with different fermentation types, and is provided by the Northeast Agricultural University Animal Science and Technology ruminant laboratory. According to the production technology, a mixing ratio of the corn steep liquor to the rice straw is determined according to a water content of the rice straw, a fermentation process is promoted through spraying the lactic acid bacteria fermentation agent, fermentation production is performed by adopting a bag storage manner, the finished product can be taken after 60 days, the required feed raw materials have wide sources, production can be performed throughout the year so as to solve a problem of utilization of green dry rice straws in different seasons, the rice straw is mixed with the corn steep liquor so as to significantly increase a crude protein content in the fermentation feed, and fermentation quality and aerobic stability of the feed are effectively increased with lactic acid and acetic acid produced through fermentation so as to provide important significance for development of ruminant animal feed resources.
Description
Affiliated technical field
The present invention relates to a kind of compound lactobacillus fermenting and producing corn steep liquor and paddy rice tangerine mixed culture fermentation feed technology utilized.
Background technology
Corn steep liquor is that the immersion water in the product processing such as cornstarch contains the byproduct that obtains behind the solid content about 60% through being concentrated into.Be rich in nutritional labelings such as soluble protein, carbohydrate, starch and lactic acid in the corn steep liquor.Discover that corn steep liquor contains several amino acids, inorganic salts and vitamin, can be used as the needs that desirable nitrogenous source satisfies the lactobacter growth breeding.Corn steep liquor is the burgundy paste, and sharp aroma is arranged, and it is low directly to sneak into the feed intake of feeding in the daily ration.In recent years, because the cornstarch production increase is very fast, supply exceed demand for corn steep liquor, and many starch factories directly discharge soak water of maize, have caused the pollution of environment and the waste of resource.
China is large agricultural country, and stalk resource is very abundant, and output is huge.Paddy stalk is a kind of as straw feed, because its crude protein content is low, and the crude fiber content height, digestibility is low, and palatability is poor, and this stalk of feeding merely can not satisfy the nutritional need of ruminant.Blue or green rice tangerine is generally adopted the processing method of silage fermentation, improves its palatability, digestibility and nutritive value.Blue or green rice straw can the air-dry yellow of rapid dehydration become the solid carbon dioxide rice straw through natural drying, and fiber content height, soluble-carbohydrate are low, can't reach the ensiling primary condition, haylage as surviving the winter is of low nutritive value, and can adopt interpolation moisture and lactic acid bacteria fermenting agent to carry out Huang storage fermentation.
The paddy rice straw that water content is different and the corn steep liquor mixed culture fermentation of different proportion change into can be by the novel fermentation feed of ruminant using, to improving the ecological environment, promote problems such as agricultural economy cycle development and solution roughage inadequate resource significant.
Summary of the invention
The object of the invention is to improve the nutritive value of straw feed, provides a kind of corn steep liquor and rice straw are mixed, by adding lactobacillus-fermented, the method for producing novel animal fermented feed.Be characterized in having solved on the one hand the paddy rice straw separately as ensiling or yellow storage fermentation raw material, crude protein content is low, fiber content height, the problem that is of low nutritive value; On the other hand, by adding the high compound lactobacillus preparation of a kind of activity, increase lactic acid, acetic acid content, effectively improved quality and the aerobic stability of fermented feed.
The object of the present invention is achieved like this: the paddy rice straw that water content is different are cut to 4-5cm long, carry out mixed culture fermentation with corn steep liquor according to a certain percentage respectively, adopt the mode of every 1000g pocket storage fermentation, prevent too much fermented feed long term exposure moldy metamorphism in air on the one hand; Adopt the mode of bag storage to ferment on the other hand, simple to operate, it is convenient to get material.The compound lactobacillus preparation that fermented feed adds is by the ruminant laboratory research and development of animal science and technology institute of Northeast Agricultural University and provides that this lactobacillus preparation is by the Lactobacillus plantarum of lactic acid producing, the Bu Shi lactobacillus that produces acetic acid and the compound lactobacillus micro storage additive agent product that the Kai Shi lactobacillus is composited by a certain percentage.
The invention has the beneficial effects as follows, select ripe dried rice straw by the dark green rice straw of gathering in the crops after the threshing and air-dry yellow behind natural drying respectively for use, the two adopts proper proportion to mix with corn steep liquor respectively, improves fermentation quality and aerobic stability by adding the compound lactobacillus preparation.Overcome the paddy rice straw through the stalk fermentation product of the method gained and carried out yellow storage or ensiling can not guarantee the to ferment drawback of nutritive value of material separately, add the protein content that corn steep liquor has effectively improved feed, wherein the yellow storage of dried rice straw fermented feed gross protein value reaches 10%, blue or green rice straw silage fermentation crude protein content of feed can reach 17%, has opened up new fermented feed source for ruminant produces.
The specific embodiment
For a more detailed description to this fermentation for example below:
Embodiment 1.Determine the mixed proportion of corn steep liquor and rice tangerine according to the water content of paddy rice straw, when the water content of paddy rice straw was 10%, corn steep liquor and dried rice straw adopted the mixed proportion of 1:2, and every 1000g mixed fodder adds the compound lactobacillus bacterium liquid (1 * 10 that 50ml has activated
5CFU/g), regulate moisture to 60% by adding sterilized water.Adopt bag storage mode, each bag silo charging 1000g seals airtight preservation, yellow storage fermentation 60 days.Open bag back took and finishes in 7 days.
Embodiment 2.When the water content of paddy rice straw was 70%, corn steep liquor and blue or green rice straw adopted the mixed proportion of 1:3, and every 1000g mixed fodder adds the compound lactobacillus bacterium liquid (1 * 10 that 50ml has activated
5CFU/g), need not to add sterilized water and regulate water content.Adopt bag storage mode, each bag silo charging 1000g seals airtight preservation, silage fermentation 60 days.Opening bag back takes in 3 days and finishes.
Claims (4)
1. one kind is utilized the compound lactobacillus preparation fermentation to produce corn steep liquor and paddy rice straw mixed culture fermentation feed technology, and its fermented product feature is: by adding the crude protein content that corn steep liquor effectively raises paddy rice straw fermented feed.
2. corn steep liquor and dried rice straw adopt the mixed proportion of 1:2 to carry out Huang storage fermentation; Adopt the mixed proportion of 1:3 to carry out silage fermentation with blue or green rice straw.
3. the lactobacillus preparation that adds of this fermented product is the compound lactobacillus preparation that is provided by animal science and technology institute of Northeast Agricultural University ruminant laboratory.
