Description

A kind of wet-type probiotic pre-mixed fermented bedding cultivation method

technical field

The invention relates to the technical field of feeding, in particular to a wet-type probiotic pre-mixed fermented bedding cultivation method.

Background technique

Ecological pig raising is both a new thing and an ancient way of raising pigs. Thousands of years ago, the working people of our country knew that crop straw, turf, leaves and new soil should be put together as a bedding bed for livestock, and by the trampling of livestock and the fermentation and decomposition of bacteria, the manure and urine would be converted into high-quality products. Organic fertilizer, and then use this organic fertilizer to grow crops, promote agricultural development, make agriculture and animal husbandry rely on each other, promote each other, and form a sustainable large-scale agriculture, which is the prototype of early ecological pig raising.

Traditional pig farms have cement floors, which require manual cleaning of manure and washing of manure with water. Especially in 10,000-head pig farms, a large amount of manure is discharged at will, causing extreme pollution to the environment and increasing the cost of feeding. For example, for a pig farm with an investment of 5 million yuan, an additional investment of 2 million to 3.5 million yuan is required for sewage treatment; a large-scale pig farm that raises 600 sows and produces 10,000 meat pigs per year will discharge the amount of sewage per day. It is 100 to 150 tons, and the annual discharge of sewage is 36,500 to 54,800 tons, which causes great pollution to the surrounding environment. There have been many cases of closure and relocation of large pig farms due to environmental pollution in my country.

In recent years, with the development of the scale and industrialization of my country's pig industry, people's demand for the quality of pork products has continued to increase, and the method of raising pigs in fermentation beds has emerged. The existing fermentation beds are made of straw, rice husks, etc. It is made by directly sprinkled with powdered bacteria, while the powdered biological agent is in a dormant state of spores and has no activity. It can only be recovered in the nutrient solution of the litter or under the action of the temperature in the pig body, and it will function after recovery. It is difficult to completely kill parasites, pathogenic bacteria and harmful microorganisms, and it is difficult to ensure the health of the pig herd.

Preferably, the drinker and the feeder are respectively arranged on both sides of the fermentation bed.

Preferably, the thickness of the fermented mattress material in summer is 60-70cm, and the pigs cannot be blown directly by a vertical fan during ventilation. After the spray system is turned on to cool down, the roller shutter is lowered by 1.5m. After the temperature in the house drops to 26°C, the spray system stops. Work, start again in 5-15 minutes, the moisture content of 20cm on the surface of the litter in summer is 60%, and the moisture content below 20cm is 40%-45%.

Preferably, the thickness of the litter in winter is 80-90cm. When dehumidifying in the southern region, close the doors and windows, open the dehumidification fan, and keep the air flow rate in the pig house at 0.3-0.4m/s without affecting the temperature of the pig house. The tidal volume should reach more than 80% of the air volume in the house within 5 minutes. The air outlet is located on the roof of the house, and the air inlet is 1.5m away from the surface of the litter. The time is early, middle and evening.

The beneficial effects are:

1. Different from the old fermentation bed, this fermentation bed is a wet-type industrialized equipment pre-stirred and cultivating bacteria (special compound beneficial bacteria) type bedding, and fully multi-process high-temperature fermentation sterilization and insecticidal eggs, wet-type beneficial bacteria pre-mixed fermentation mattress The maximum temperature of the feed through stirring and fermentation can reach 65-70°C. Under operation, the heat generated by rapid fermentation and decomposition can reach 45-60°C or higher, which is beneficial to kill parasites, pathogenic bacteria and harmful microorganisms, and ensure the health of pigs. For example, PRRS virus can be killed in 20 minutes at 56°C, pseudorabies virus will lose its activity at 4-37°C in 1-7 days, and swine fever virus will lose its activity at 60°C in 2 hours. active. The wet whole-bacteria pre-mixed fermented mattress material greatly inhibits the reproduction of pathogenic bacteria and creates a whole-bacteria beneficial bacteria environment.

2. The surface temperature of the wet-type whole-bacteria pre-mixed fermentation bed can be maintained at 30 ± 3 degrees in the dog days of summer, and it is easy to spend the summer. When the outdoor temperature drops below zero in winter, the wet whole-bacteria pre-mixed fermentation bed can keep the surface temperature at 30 ± 3 degrees. Mixed fermentation bed, the surface temperature of the bedding material is also maintained at 22-25 degrees, this temperature is completely safe for winter without any energy consumption, such a fermentation bed is equivalent to laying an "electric mattress" for the pigs, and the bedding material works Normal and effective decomposition, unlike the current market fermentation bed, the temperature has been uncontrollable to 47-60 degrees in summer. It is necessary to increase the cement rest table in the barn, which wastes the space of the barn. "Bacteria" also hibernate. They must be heated to work properly.

3. The wet whole-bacteria ready-mixed fermentation bed and the special compound fermentation bed are liquid, which is different from the powdered biological inoculum commonly used in the market, and the powdered biological inoculum is in a dormant state of spores, inactive, and only in the mat It can only be recovered under the action of the feed nutrient solution or the temperature in the pig body, and it can function after the activity is restored. This product uses liquid biological bacteria agent, which has strong biological activity. It can exert its effect on the bed and pigs without going through the activation process. This is also the great feature of this wet bed. Moisture, proper moisture can help the activity of special bacteria, accelerate decomposition and the growth of special compound beneficial bacteria. This breeding method requires the installation of high-pressure sprayers near the top of the barn, which can reduce the temperature and humidity of the barn air in summer! When the hot air of the barn rises, when the hot air at the top of the barn touches the high-pressure fine mist, the water molecules drop in the cooling zone, and the negative ions generated by friction with the air make the air in the barn fresher. Convective wind is formed in the barn under the action of the circulation of the barn! The air temperature of the barn is greatly reduced, and the air quality is fresh. This breeding method requires roller shutters to be installed around the barn for seasonal climate adjustment, and high-pressure fine mist spraying is required. During operation, the roller shutter is required to be lowered by 1.2-1.5 meters. The key point is to form a microclimate area for the barn. The effect of cooling and convective wind in the barn in high temperature summer is more obvious.

4. The present invention makes use of the characteristics of pigs, and sets the drinking fountain and the feeding device on both sides of the fermentation bed respectively. When the pigs eat the feed, they will feel thirsty and drink water from the drinking fountain on the other side. When the pigs are walking, they will drag the bedding material about 20 cm on the surface of the rake fermentation bed, so that the feces and the bedding material are evenly mixed, which accelerates the decomposition of the feces and helps reduce the generation of peculiar smell.

Detailed ways

Below in conjunction with accompanying drawing, technical scheme of the present invention is further explained:

Example 1

A wet-type probiotic pre-mixed fermented bedding cultivation method, comprising the following steps:

1) For the production of litter, put the straw and agricultural waste chaff, sawdust, rice bran, and pig manure into the stirring equipment for mixing, adjust the water content of the stirring and spray the special litter liquid beneficial bacteria, fully stir and mix evenly , stack the stirred litter, because the special liquid beneficial bacteria are high temperature resistant bacteria and then start high temperature fermentation, the stacking time is 7-8 days, three consecutive times, after more than ten days of stacking, the litter is turned by this method. The maximum fermentation temperature can reach 65-70℃. Under operation, the heat generated by rapid fermentation and decomposition can reach 45-60℃ or higher, which is beneficial to kill parasites, pathogenic bacteria and harmful microorganisms, and ensure the health of pigs; as shown in Figure 1 As shown, most harmful bacteria can be killed at above 80°C, PRRS virus can be killed at 56°C in 20 minutes, and pseudorabies virus can be killed at 4-37°C in 1-7 days. Inactive, the swine fever virus is inactive in 2 hours under the condition of 60 ° C, the temperature of the litter can reach above 80 ° C in the stacking high temperature fermentation, killing most harmful bacteria; wet whole bacteria pre-mixed fermentation mattress This greatly inhibits the reproduction of pathogenic bacteria and creates a whole-bacteria beneficial bacteria environment, which can kill various harmful bacteria and insect eggs, and reduce the survival conditions of various bacteria and molds through high-temperature fermentation.

2) For the production of the fermentation bed, the fermented bedding material is evenly laid on the fermentation house, the thickness of the bedding material is 60cm-90cm, the rake is flat, and the pigs can be fed after 24 hours. If the pigs are not fed after half a month, then Appropriate amount of nutritional supplements (rice bran, etc.) must be added in time, and the operation should be repeated every two weeks until the pigs are fed; when adding nutritional supplements, the supplementary materials should be spread evenly on all parts of the surface of the litter, and then raked down. The bedding material is 30 cm deep, and the auxiliary material and the bedding material are mixed evenly; this operation is to ensure the normal fermentation operation of the bedding bed and keep the temperature normal; if the above treatment is not done in time, it will cause a dead bed.

3) Maintenance of fermentation bed:

a. Burying manure: Dig a 30cm deep hole in the fermentation bed every 1m-2m to fill the pig manure, and change the position of the hole every day; so that the pig manure can be evenly distributed in all corners of the bedding bed, the purpose is to: on the one hand, avoid The excessive concentration of pig manure in some parts and the untimely decomposition of pig manure have caused a series of serious problems. On the one hand, it is beneficial for all the fermenting bacteria in the litter to obtain sufficient food and to function normally.

b. Breathability and light transmission: Pull up the roller shutters on both sides of the pig house at noon every day, and ventilate for 1-2 hours, so that the pigs can get more exposure to the sun, which is beneficial to the healthy growth of the pigs.

c. Control the thickness of the litter: when the fermentation bed collapses, replenish the new unfermented raw materials in time. After laying the new raw materials, spray the diluted fermentation liquid, and then turn down the rake for at least 30cm, and put the new raw materials on the pad. The materials should be mixed evenly, and the spreading and raking should be completed on the same day; to avoid dust on the surface of the new litter, causing the pigs to cough and pant.

d. Observe the humidity of the bedding material: If the temperature of the fermentation bed is normal, but the humidity of the bedding material is too high and the water content is greater than 60%, new raw materials should be replenished in time to keep the fermentation bed working normally. The humidity management of the fermentation bed is very important, which is related to the energy Whether the fermentation is normal, whether the fermentation bed can work normally, if the bedding is too dry, it must be sprinkled with water. If it is too wet, new special cooked fermentation bedding must be added. Note that if the temperature of the fermentation bed is normal (measured by a thermometer), but the humidity of the bedding is too high , At this time, new raw materials should be replenished in time. If left unchecked, it will affect the normal operation of the fermentation bed.

e. Stocking density: 7～30㎏ small pigs, the required bed area of each head is 1～1.2㎡, 30～100㎏ medium pigs, the required bed area of each head is 1.2～1.5㎡. For medium-sized pigs of 100-150 kg, the area of the bedding bed required for each head is 1.5-1.9 square meters. Pigs of different sizes have different amounts of feces and urine. In addition, the management level of the breeders is different, and the fermentation flora decomposes the feces and urine. There are also differences in the capacity of pigs, so in order to ensure that the manure can be decomposed in time, it is necessary to maintain an appropriate stocking density to ensure the healthy growth of the pig herd.

f. Nursing after slaughtering: After all pigs are transferred to the slaughter, first place the fermented bedding material to dry for 2-3 days, and then thoroughly and repeatedly turn the bedding material from the bottom to be evenly distributed. According to the situation, the bedding material, rice bran and beneficial fermentation can be appropriately supplemented After 1 week, the next batch of pigs can be reared. If conditions permit, the litter can be stacked and fermented once, and the effect is better; after the temperature in the middle of the litter pile reaches 60 °C, the litter is raked and leveled. After 24 hours you can enter the pig.

The beneficial bacteria and proportions used in the production process of the litter are as follows:

Lactobacillus acidophilus 23%-40%;

Saccharomyces cerevisiae yeast 22%-33%;

Bacillus amyloliquefaciens 17%-32%;

Rhizobus sp. filamentous bacteria 11%-25%;

Streptomyces sp. Actinomycetes 18%-24%;

Rhodopseudomonas capsulate photosynthetic bacteria 9%-22%;

Licheniformis Bacillus subtilis 19%-29%;

Lactobacillus acidophilus 23%-40%.

There is a spray system above the fermentation bed. The spray system consists of several high-pressure sprayers. There are three purposes for setting the spray system: 1. In summer, the temperature and humidity of the air in the barn can be reduced. When the hot air at the top of the barn touches the high-pressure fine mist, the water molecules drop in the cooling zone, and the negative ions generated by friction with the air make the air in the barn fresher. It is under the circulation of the hot air rising and the moist and cold air falling in the barn barn. Convective wind is formed, the air temperature of the barn is greatly reduced, and the air quality is fresh; 2. Although the beneficial bacteria can decompose most of the pig manure, the pig manure will still produce ammonia, ammonia sulfide, indole and other odors, resulting in irritating odors. Since irritating gases such as ammonia and ammonia sulfide are all soluble in water, when the high-pressure spray sprays water mist, these gases will drop to the surface of the litter, prompting the special compound beneficial bacteria to decompose these irritating gases, so as to achieve no pollution in the pig house. 3. The pigs will produce dust when they move around, which will easily lead to some diseases of the respiratory tract and affect the normal growth of pigs. Spraying water mist can moisten the surface of the litter and avoid dust.

The liquid sprayed by the spray system contains special compound beneficial bacteria groups. The compound beneficial bacteria and the proportions in the spray liquid of the spray system are:

Lactic acid bacteria 13%-33%;

Lactobacillus lactic acid bacteria 18%-22%;

Licheniformis Bacillus subtilis group 19%-29%;

Lactobacillus acidophilus 23%-40%;

Saccharomyces cerevisiae yeast 22%-33%;

Bacillus amyloliquefaciens 17%-32%;

Streptomyces sp. Actinomycetes 18%-24%;

Rhodopseudomonas capsulate photosynthetic bacteria 9%-22%.

The feed consumed by pigs contains beneficial bacteria. The types and comparisons of beneficial bacteria are as follows:

Lactic acid bacteria 13%-33%;

Lactobacillus lactic acid flora 18%-22%;

Saccharomyces cerevisiae yeast flora 17%-28%;

Licheniformis Bacillus subtilis 19%-29%;

Photosynthetic bacteria 15%-23%;

Actinomycetes actinomycetes 19%-31%.

The drinker and the feeder are respectively arranged on both sides of the fermentation bed. Taking advantage of the characteristics of pigs, the drinker and the feeder are respectively arranged on both sides of the fermentation bed. Drinking water at the device, because the pig's trotters cannot be bent, the pigs will drag the litter about 20 cm on the surface of the rake fermentation bed when walking to accelerate the decomposition of the feces, and there is no need to manually turn the litter.

The thickness of the fermented mattress material in summer is 60-70cm. When ventilating, it is not allowed to blow directly on the pigs by means of a vertical fan. After turning on the spray system to cool down, lower the roller shutter 1.5m. After the temperature in the house drops to 26°C, the spray system stops working. 5 -15 minutes to start again, the moisture content of 20cm on the surface of the litter in summer is 60%, and the moisture content below 20cm is 40%-45%.

The thickness of the litter in winter is 80-90cm. When dehumidifying in the southern region, close the doors and windows and open the dehumidification fan.
