Description
Technical field
The present invention relates to field of feed, more particularly to a kind of nutrition sweet potato dreg fodder and its production technology.
Background technology
With economic development and the raising of living standards of the people, livestock and poultry group food generally comes across the daily meals of people
In, the fast development of animal farming industry is thereby promoted, feed demand amount constantly increases, and especially the demand of protein feed is drastically
Increase.Though China is large agricultural country.But actually Grain Supply-demand Balance relation in China's is more weak, the most thorny issue is exactly grain
The shortage of food and feed.For overall angle, 400 kilograms of the lazy weight of the Chinese per-capita share of grain, and wherein percent
40 grain is all used in Feed Manufacturing.It is expected that 2020 to 2030 in this 10 years, the grain aggregate for Feed Manufacturing
50 or so percent will be risen to.From the point of long-term development, the problem of livestock strives grain with people is also badly in need of solving.
Therefore feed resource must be expanded, develops new feed resource, improve feeding quality to meet livestock and poultry to feed
Wilderness demand.In recent years, countries in the world are deepened to fermented feed attention degree, and oneself begins to use fermentation to raise through some country
Material, domestic fermented feed have also obtained preferable development.Therefore, feed industry is developed rapidly, efficient, the healthy green type of production
Feed turns into the livestock breeding industry task of top priority.
Fermented feed be must be taking human as control condition based on, by microorganism own metabolism, will have mineral
The nutrients of matter, animal property and plant property is converted to polysaccharide, protein and fat, is converted into organic acid, enzyme, more skins etc.
Small-molecule substance, and easily digested and assimilated by livestock and poultry, and have no toxic side effect.
Chinese patent (number of patent application：201510974707.7) a kind of fermented feed and preparation method thereof is disclosed, should
Fermented feed comprises at least a kind of fermented bacterium, a kind of base material, a kind of nitrogen source, a kind of carbon source, inorganic salts；Described fermentation is raised
The nutrient solution Ingredients Weight ratio of material is：Industrial milk powder 3-7 parts, micro- 1-2 parts, detritus acid potassium 1-5 parts, algae essence 1-
2 parts, amino acid powder 1-3 parts, milt 1-3 parts, molasses 3-7 parts, distilled water 50-70 parts；Described fermented bacterium is by lactic acid bacteria, light
One or more compositions in synthesis bacterium, ferment bacterium, withered grass bacterium, huge bacillus, radiation bacterium, nitrifier, acetobacter etc.；Act on
In the shell of cereal, rice straw, straw, maize straw, bagasse, lumber fibre etc. on the base material of one or more compositions, through hair
Made fermented feed can merge use with conventional feed after ferment and follow-up making, be applicable to domestic birds and animals.
The content of the invention
Sweet potato waste is ground by fresh sweet potato, is rubbed and is washed, and precipitation forms.It is relatively rough, wherein big containing abundant cellulose, volume
In starch granules, the coefficient of expansion is lighter than starch granules again also greater than starch granules, proportion.Sweet potato waste starch water absorbing capacity is strong, but
Viscosity is poor, and sweet potato waste as agricultural byproducts, in rural area, as waste residue abandoned, and causes the wasting of resources by the overwhelming majority.In order to
Solves above mentioned problem existing for prior art, the invention provides a kind of nutrition sweet potato dreg fodder and its production technology.

Test case 1
Swine rearing test is carried out to nutrition sweet potato dreg fodder prepared by embodiment 1-6.
Experiment is carried out according to pig farm conventinal breeding management, and test group is raised by fixation test person, in the hope of management condition
Unanimously.It is good in confined swine housing, lighting and ventilation to test swine rearing.By body condition is good, body weight 10-12kg 120 Hubei are white
Pig is randomly divided into six test groups, and every group 20, experimental period is three months.During experiment, respectively in the morning 8:00th, noon 12:
30 and at night 17:300 feedings, with Duckbill-type drinking trough free water.Pig house, hopper and tank are cleaned, disappeared before experiment
Poison, after on-test, pig house cleans once daily, sterilizes once, to keep the sanitary condition of cleaning.
The feeding of average day and average daily gain to embodiment 1-6 pig are tested.Average daily gain method of testing：Examination
Test pig the 1st day empty stomach after the 1st day on-test and off-test to weigh, and each group test pig is calculated according to weighing results
In the average daily gain of experimental period.Specific test result is shown in Table 1.
The specific testing procedure of tenderness：After swine rearing three months, slaughtered, taken on trunk size for 4cm × 3cm ×
1cm tenterloin meat sample, surface fat is removed, meat sample is fitted into wrapping in plastic film bag places 24 hours progress corpse after 15 DEG C
Stiff pre-treatment, with after 4 DEG C cure 24 hours, then room temperature place 1 hour；At thermometer insertion muscle center, meat sample is put
Enter in 80 DEG C of thermostat water bath, continuous heating to muscle central temperature is cooled to muscle central temperature up to 70 DEG C, then by meat sample
Up to 20 DEG C；Sampled with a diameter of 1.27cm rounded sample device along muscle fibre, with Texture instrument (Britain Stable Micro
Systerms companies provide, model TA-X12i) survey shearing force, shearing tool be Warner-Bratzler cutters, blade and
The meat fiber of sample is in 90 °, and the fall maximum of cutter is 28mm, and cutter maximum pressure is 50kg, and shear rate is
2mm/s.Each embodiment takes 5 pieces of meat samples, and every piece of meat sample surveys 3 positions, takes its average value.
The specific testing procedure of drip loss：After swine rearing three months, slaughtered, hog on hook is small in room temperature placement 1
When；The tenterloin meat sample for taking size to be 4cm × 3cm × 1cm on trunk, weighs (W1)；Then meat sample is suspended on iron wire and filled
In the polybag of gas, it is placed in 4 DEG C and hangs 48 hours, take out, gently wipe meat sample surface juice away with clean filter paper, weigh (W2).
The calculation formula of drip loss is：Drip loss (%)=(W1-W2)/W1 × 100.Each embodiment takes 10 pieces of meat samples,
Take its average value.Concrete outcome is shown in Table 1.
Table 1：Test result table
2 sweet potato wastes of the invention are through digesting after fermentation, and content of lignin declines in fiber, and insoluble diedairy fiber is changed into can
Soluble dietary fiber, increase the content of soluble dietary fiber, so as to improve its materialization, functional activity, improve the utilization of feed
Rate and palatability.Super-pressure can destroy the cell membrane and cell membrane of substrate when embodiment 3 digests, and accelerate the contact speed of enzyme-to-substrate
Rate, and enzyme activity can be improved, finally shorten the reaction time.
