Abstract
The present invention relates to a kind of ecological pig-culturing methods, provide a kind of method raised pigs using ecological technique, this method will adjust environment in domestic animal gastrointestinal tract and combine with improvement farm's external environment, composite probiotics feed additive is added in feed feeds live pig, external environment is improved using fermentation bed simultaneously, the cultural technique of ecological environment significantly improves the utilization rate of feed inside and outside this change, enhance immunity, the premunition of live pig, and environmental pollution and production cost are substantially reduced, the multipurpose of breeding ecological, raise pigs safe and product nutrient laden is reached.
Description
Technical field
The present invention relates to livestock and poultry cultivation methods, are exactly a kind of ecological pig-culturing method, improve the conversion ratio of feed, reduce live pig
The death rate, improve meat quality, it is ensured that drug residue free, while improving the ecological pig-culturing method of farm's environment.
Background technique
Currently, Safety of Food Quality has become very sensitive topic, and in recent years, some illegal feeds or pig raising enterprise
Industry adds various separated drugs for the maximization of profit-push into feed and feed addictive wantonly, mainly includes steroids
(preparations such as such as clenbuterol hydrochloride, antibiotics drug (such as sulfanilamide (SN), chloramphenicol) or excess addition copper, arsenic, selenium, cause this to drug
A little drug or heavy metal exceeded residuals in pork, seriously affect human health.
Meeting the needs of people are to animal food simultaneously, livestock and poultry and excrement effect on environment are far-reaching.First is that water body
With the pollution of soil.Untreated swine manure wastewater is discharged into rivers and lakes, destroys water environment, water quality deterioration is caused to become black
Smelly and aquatile is dead;Every live pig rinses colony house during the growth process and needs to consume 5 tons of water, and national ten thousand pig farms are very
More, water resource waste is surprising, and the aggravation mankind are in short supply with water.Untreated feces of livestock and poultry and sewage can lead to soil aperture gambling
Match causes Soil ventilation, water penetration decline to have hardened, seriously leads to soil quality.Second is that the pollution to atmospheric environment.Excrement hair
Ferment generates the toxic, harmful components such as a large amount of ammonia, ammonium sulfide, methane, can endanger the health of keeper and surrounding resident,
It is soluble easily in water for example, ammonia has penetrating odor, be often dissolved or be adsorbed in animal house damp ground, on wall, to people
Body mucous membrane irritation is big, Yi Yinqi mucous hyperemia, laryngeal edema, bronchitis etc..Third is that human health and animal husbandry development
Influence.Livestock manure fermented causes pathogen, helminth and mosquitos and flies mass propagation, causes the spread in china of zoonosis.
Live pig survival rate is low in this environment and fattens the sound development that daily gain in pigs delays, hinders animal husbandry.Pollution
Underground water can also cause damages to human health.
Summary of the invention
The object of the present invention is to provide a kind of inside and outside ecological pig-culturing methods, by improving outside live pig vivo environment and farm
Environment, to produce health-nutrition safe pork.
The technical solution of the present invention is as follows: the present invention is to improve farm's external environment using deep-litter systems, while using multiple
Probiotics alternatives to medication health care product is closed, live pig vivo environment is improved.Ecological fermentation bed production method is: ecological fermentation bed depth
Degree is 90-110cm, divides upper layer and lower layer, and lower layer is the cornstalk of 25cm, log bits, soil and the sea salt that upper layer is 75-95cm,
And be added after 0.7 ㎏ of probiotics strain is mixed well and inserted in fermentation bed by every square meter bed area, fermentation bed and cement floor
For 4.5:1, humidity rests in 55~65%, can be into pig after 7~9 days.Every 20~25 days with five percentages
One of plant nutrition liquid water sprinkling bed surface adjust holding humidity, when padding height reduces in fermentation bed, should be replenished in time
Appropriate sawdust.
The beneficial effects of the present invention are: being fed during the feeding process using composite probiotics feed additive to pig, and answer
The mode combined with deep-litter systems, this inside and outside ecology, not only reduces the death rate of live pig, improves the conversion of feed
Rate, it is ensured that drug residue free in pork, and the protein content, total amino acid content and content of glutamic acid of pork are improved, it drops
The low fat content of pork, keeps pork not only in good taste, full of nutrition, and safe nonreactive.
Specific embodiment
Following embodiment is that the present invention makees further to go out to illustrate.
In terms of improving outer ecological environment, by applying deep-litter systems, accomplish " waste zero-emission, sewage zero-discharge, sky
Gas no pollution, respiratory tract zero infections ";In improving in terms of ecological environment, by applying composite probiotics feed additive, adjust
Body gastrointestinal tract normal flora keeps microecological balance, improves the utilization rate of feed, solves medicament residue problem, improves simultaneously
The nutritive value of pork.
The preparation of plant nutrition liquid: the fresh and tender plant that acquisition resistance is strong, cold resistance is good, vitality is strong, the speed of growth is fast
(acquire in the morning before the dew is dried).Every 1 ㎏ plant, which sprinkles, to be put into osculum pithos after the old brown sugar of 500g is mixed thoroughly and uses touch paper
Sealing, environment temperature can be taken off liquid after 7 days~10 days at 25 DEG C or so, nutrient solution.It is placed on cool place and is protected from light place
It saves stand-by.
Fermentation bed production: fermentation bed depth is advisable with 90-110cm, divides upper layer and lower layer, and lower layer is the cornstalk of 25cm, on
The log that layer is 75-95cm considers the soil (15%) and big grain original sea salt of (93%) (preferably former weed tree sawdust), uncontaminated mistake to be worth doing
(0.5%), it and is added after 0.7 ㎏ of probiotics strain is mixed well and is inserted in fermentation bed by every square meter bed area, fermentation bed
It is 4:1 with cement floor, humidity rests in 60% or so, can be into pig after 7~9 days.
Fermentation bed management: forbid in fermentation bed using chemicals and disinfecting drug in breeding process.Pig has fixed point size
Just habit will look after and guide pig and change this habit, while when excrement is accumulated, and administrative staff can be let go or buried.
It, can be wet to adjust with five centesimal plant nutrition liquid water sprinkling bed surfaces every 20~25 days when fermentation bed humidity is inadequate
Appropriate sawdust should be replenished in time when padding height reduces in fermentation bed in degree.
Composite probiotics feed additive preferably comprises lactobacillus acidophilus, Bacillus bifidus, streptococcus thermophilus, plant cream bar
Bacterium.Composite probiotics feed additive can be added in feed according to feed 4-7 kg per ton, feed to pig.When feeding pair
When as lactation and weanling pig, preferably it is added in feed according to feed 5-10kg per ton, feeds piggy;When feeding object
When for growing and fattening pigs, preferably it is added in feed according to the ratio of feed 3-5 kg per ton.
Claims (1)
1. a kind of ecological pig-culturing method, it is characterised in that: ecological fermentation bed depth is 90-110cm, divides upper layer and lower layer, under
Cornstalk of the layer for 25cm, log bits, soil and the sea salt that upper layer is 75-95cm, and be added by every square meter bed area
0.7 ㎏ of probiotics strain is inserted in fermentation bed after mixing well, and fermentation bed and cement floor are 4.5:1, and humidity rests in 55
