Fermented mattress material formula: The formulation of various litter (fermentation layer) is as follows: In the following table, the dosage of a 20 square meter pig house, the total height of the mat layer is 90 cm (unit: kg) Other production raw materials include peanut shell coarse powder and straw coarse powder. formula Formula example (unit: kg) Formula 1 Sawdust 1700+Corn 15+Fengwang Pig Fermentation Bed Starter 2+ Water 1000 Formula 2 Sawdust 1700 + corn 40+ Fengwang pig fermentation bed fermentation agent 2+ water 1200 Recipe 3 Sawdust 800+ rehmannia or rice gluten 900+ corn 15+ Fengwang pig bed fermentor 2+ water 1000 Formula 4 Sawdust 500+ rehmannia or rice bran 1200+corn 15+ Fengwang pig bed fermentation 2+ starter 2+ water 1000 Recipe 5 Sawdust 1600+ pig manure 400+ corn 40+ Fengwang pig bed fermentation starter 2+ water 1000 Formula 6 Peanut shell (simple crushing) 800+ Sawdust 900+ corn flour 15+ Fengwang pig's broth Fermentation bed 2+ water 1000 Remarks: In the above recipes, although different raw material ratios are used, in actual operation, it is not necessary to mix the various raw materials evenly and then supplement them into the columns. Instead, they can be separately added, for example, the bottom layer can be used. Smashed rice hulls, small hibiscus, unsmashed peanut husks, unsmashed cottonseed husks, coarse cotton rods, etc. are not easily decomposed, or the bottom layer can be smashed, but the upper layer is at least 30 cm. Use smashed sawdust (mixed or single ingredients are acceptable), otherwise the pig will feel skin irritation and discomfort. from already Assume meter pad material Match square The principle of litter formulation design is that the principle of litter selection is: Inert (crude fiber is not easy to be decomposed) raw materials, the hardness is larger, there is a proper amount of nutrients such as energy, the inertness of various raw materials and The order of hardness is as follows: sawdust> reed powder (substance after smashing rice grains)> coarse cotton powder> peanut shell> cotton rod coarse powder> other straw coarse powder Feeds such as rice bran or wheat bran ensure that the carbon-nitrogen ratio of the litter is around 25 to 1, otherwise all inert materials such as sawdust will not be able to ferment, there will be no nutrition, and it will not be able to ferment and produce heat, so it needs to be fermented. Add appropriate amount of corn flour. Note that the particle size of the inert main raw material can not be too fine or too coarse, such as the reconstituted powder, with a 5 mm sieve to crush the degree, the wood chips should also use coarse wood chips, with a 3 mm sieve of "sieve" as degree. Or use coarsely crushed raw materials. As far as sawdust is concerned, as long as it is non-toxic, hard-sawed sawdust can be used. Some people say that it is wrong to use sawdust such as pine that contains grease. Sawdust from pine trees and eucalyptus containing special smell can be used. The average weight of bedding used is at least 80-150 kilograms per square meter. Thickness of dunnage: In the southern part of the high temperature, the total height of the dunnage can reach 60 centimeters; the central region should reach 70 centimeters, and the cold regions in the north must be at least 80 centimeters. Since the dunnage will be compacted at the beginning of use, the thickness will be reduced. Therefore, the thickness during construction is increased by 20%. For example, the planned total height of the dune in the south is 60 cm, and the thickness when the dunnage is laid is 74 cm. Every year, according to special circumstances, such as accidentally leaking rain, you can use a small amount of litter to absorb excess rainwater, or the litter is sinking. It is also a direct supplement of litter. 3, litter production process Simple operation process: 1 Mix Corn + Fengwang Starter Mix 2 Other litter materials Simply mix 3 Go to the fermented bed under construction 30 liters into padding 4 Sprinkle the mixture of Fengwang starter and corn flour 5 Simply mix , repeat 3 to 5 steps, the top 20 cm using a slightly fine sawdust + water + starter mixing simple, and finally a little step on the entire bedding can be real. If you cover it with a film, the fermentation rate will increase. In the above operations, the amount of water used for the litter under the cover layer is not absolute and needs to be controlled flexibly. The optimum moisture content is: splashing water and mixing it, grasping it, and grasping it. The amount of water. Under normal circumstances, the total feed water ratio does not exceed 1 to 0.7. The fermentation bed will feel warmer on the second day, and water should be added on the 3rd and 7th days, respectively, and can be directly sprayed on the fermentation bed with proper amount of water. The fermented litter can be used for 3 days in winter and 5-7 days in summer. The covered film was removed, and 20 cm of surface litter was loosened with tweezers and allowed to breathe for 1 day. The pig entered the day before. If the surface was dry, dust could be sprayed on the fermentation bed in an appropriate amount. The next day, let the pig stay in the fermentation bed. (3) Fermentation process. In this way, after 5 to 10 days of fermentation (this is related to temperature, high temperature and fast fermentation), the inner temperature rises up to 70 degrees, and then slowly cool down, the surface temperature is slightly warm and humid, that is, you can put Into the growth of finishing pigs for feeding. During the fermentation process, the layer temperature can reach 40 degrees or more in the second day in general, and can be detected by inserting a thermometer into the material within 30 centimeters. After that, it gradually rises to 70 degrees or more, and after several days of decomposing, the middle is opened. , that is, open 30 cm deep, if you smell no ammonia smell, the smell is pleasant, it is relatively fresh raw material taste or light wine flavor, you can use. The temperature in the middle layer should still be about 40 degrees. (4) Put the pig into the house for feeding The fermented litter can be used in winter for 7-10 days and 3 days in summer. Remove the covered film or the straw layer (or straw layer) used for covering. Use a tweezers to loosen the 20-cm padding on the surface and let it breathe for 1 day. The pig enters the previous day and uses 5 kg of water + 200 kg of water. Spray on the fermentation bed. The next day, let the pig stay in the fermentation bed. Pigs entering the same fermentation bed try to select pigs in the same litter, and the pigs in different litters will battle each other two days before entering the fermentation bed. This is normal. Before the first insecticide, and make the appropriate immune. Gravid sows, empty sows, and pre-pregnancy sows can live on a fermentation bed, and during late pregnancy, sows are recommended to move to the maternity or nursery.
