The feed made from chicken manure fermented by Yijia beneficial bacteria liquid is made of wheat bran, rice bran or grass powder as chicken house litter in advance. The weight ratio of litter to chicken manure is about 3, and the moisture content of the mixture of chicken manure and litter is controlled at about 3. It is required that the chicken manure collected must be fresh chicken manure free of diseases. It should not exceed 3 days in summer and 3 days in winter. The fermentation effect of chicken manure collected on the same day is the best. If chicken manure with large doses of antibiotic additives is fed for a long time, the fermentation treatment with Yijia beneficial bacteria liquid will not be effective. Preparation method: Mix one ton of chicken manure litter mixture with 3 kilograms of beneficial bacteria liquid and gram of brown sugar. First, calculate the amount of bacterial liquid and brown sugar according to the amount of chicken manure mixture to be processed. First dissolve the brown sugar with a small amount of warm water at about ℃, then add an appropriate amount of cold boiled water to dilute it, then add the required Yijia beneficial bacteria liquid, and press Add enough water to handle the amount of chicken manure and litter, mix well and set aside. Put the collected chicken manure litter mixture into the fermentation tank in layers (small chicken farms can use jars or tanks). Each layer is centimeters thick. Spray the diluted bacterial solution in proportion. Spray the bacterial solution once for each layer of material added until the storage is full. , seal with plastic film for fermentation. At normal temperature, fermentation can be completed in ~ days. The successfully fermented chicken manure has a sour aroma instead of the stinky smell. The chicken manure is covered with white mycelium and can be used to feed pigs, dairy cows and other animals. When feeding, you should pay attention to follow the principle of starting from less to more and slowly adapting. That is, the amount of fermented feed can be added on the first day, and on the second day, gradually increase until it is about 100%. Pigs love to eat, are disease-free, have ruddy and shiny fur, and like to sleep. They can replace 50% of concentrated feed, saving hundreds of yuan in feed costs per pig, and are worthy of vigorous promotion.
Fermented chicken manure with Yijia beneficial bacteria liquid as fertilizer
If chicken manure is fermented with Yijia beneficial bacteria liquid, it must be well-rotted and can be odorless, tasteless and harmless. The compost will be soft and yellowish brown, and there will be Gray-white mycelium, about organic matter. Operation: Spread the dry chicken manure on the ground in a long strip, water it with 3% of the weight of the chicken manure, and sprinkle 1 kilogram of beneficial bacteria liquid per ton of chicken manure. You should first add rice bran or wheat bran to dilute it, and add 1 kilogram of superphosphate. To deodorize, add grass powder or peat ~kg. Then turn over the compost two or three times and pile it into a rectangular pile of material about one meter high and one meter wide, and drill holes on the top of the pile for ventilation. Finally, cover the compost pile with a rectangular plastic sheet. The plastic sheet is in contact with the ground, and a heavy object is pressed every meter to ventilate the film and prevent it from being blown up by strong winds. In summer and autumn, the film should be removed and ventilated once in the morning and evening (~ hour). When the weather is fine, the film can be removed in the evening of the first day and covered in the morning of the next day. After retting for ~ days, the stack temperature can rise to ~°C. If it is fresh chicken manure, a layer of straw powder should be spread on the ground first. Rice bran, grass powder, peanut shell powder, and peat can also be used instead. Then wet chicken manure is spread on top, and urea is sprinkled according to the weight of the pile. Sprinkle about kilograms of superphosphate per ton of weight, mix kilograms of beneficial bacteria liquid with bran or rice bran and sprinkle in. During the fermentation process, turn over the compost twice and pile it into a pile of about 1 meter wide and 1 meter high with no limit to the length. Use a stick to make ventilation holes in the pile and cover it with a plastic sheet to keep it warm, moisturizing and fertilizer-preserving. Special attention should be paid to ventilation. You can turn the pile once after it has been soaked for several days, and it will be fully cooked after it has been piled for several days.
The high price of feed has made many farmers increasingly focus on reducing production and feeding costs. Although the pig industry is highly profitable at this stage, the rise in feed prices has also made many pig farmers smack their tongues. Although feeding chicken manure to pigs is nothing new, there are very few pig farmers who can apply it in reality: some are because they don’t know how to process it, some don’t know enough about the feeding methods, and some? I want to feed but I don’t know the scientific ratio.
Due to the widespread use of compound feed to feed chickens, the nutritional content of chicken manure has been significantly improved. Pigs eating chicken manure are as appetizing as humans eating chocolate. It not only greatly reduces the cost of feeding, but also helps to purify the environment. It is a very affordable technical measure.
The technology of chicken manure feeding pigs is essentially the recycling of feed resources and has been widely promoted and applied around the world.
Nutrients in chicken manure
In addition to providing almost all minerals (especially calcium), chicken manure also provides a large amount of protein, but its digestibility is low and should be combined with feeds with higher energy. Get up and feed the pigs.
Nutritional components of chicken manure
There are many trace elements, vitamins, most B vitamins and other vitamins or vitamins in fresh chicken manure, the amount of which is much greater than the original feed. In addition to vitamins, chicken manure contains many unidentified nutritional (growth) factors. , Processing of chicken manure
Chicken manure must be processed as soon as possible to prevent rapid decomposition and retain its complete nutrients. It is generally required to collect at least once a day.
There are many methods for processing chicken manure, and many processes can process the manure into stable products. Each poultry farm can choose any one according to the actual situation.
Properly processed chicken manure has a good appearance, taste and smell, and has no original bad characteristics. Fermented and siled chicken manure has a wine aroma, and dried chicken manure has a dried paste aroma, both of which can achieve the purpose of deodorization and sterilization.
Ordinary closed fermentation method: Put fresh chicken manure into an appropriate container, add appropriate water (in winter, add ℃ hot water), seal it, and use the microorganisms in the chicken manure to ferment naturally. During fermentation, the ambient temperature is required to be no less than ℃. When the fermentation temperature exceeds ℃, the container must be turned over. When the temperature is constant and the same as the outside temperature (it takes about days), the fermentation is completed.
Closed fermentation treatment can significantly improve the nutritional value of chicken manure fed to pigs. Compared with fresh chicken manure, the contents of crude protein, total amino acids and pig essential amino acids in fermented chicken manure increased respectively.
Natural drying method: Place a certain amount of fresh chicken manure on the cement floor or a washed and dried plastic sheet, and dry it in the sun to allow the chicken manure to dry naturally (the moisture in it is reduced to below).
This method is greatly restricted by the weather, so a plastic greenhouse must be built on top. Protect from rain.
Mechanical drying method: Spread the fresh chicken manure into a thin layer, and then put it into a preheated electric-heated blast box to dry at ℃ for 3 minutes. There are also large-scale drying equipment that can be used to bake and blow hot air at ℃ hours or ℃ hours. In foreign countries, there are ℃ seconds to complete the dehydration process. The advantage of this rapid drying is that it can fully retain the nutrients of the feces (only lose -), and at the same time achieve the purposes of deodorization, sterilization and weed seed elimination.
In recent years, my country has successfully developed thermal spray treatment equipment and microwave treatment equipment, which have very good effects and can be used.
Silage
Chicken manure silage is a simple and easy processing method, especially when the poultry farm has established a silage tower, the advantages are even more obvious. Small farms can also use plastic bags, silage kilns or coarse drainage pipes (diameter: .m) for silage. The drainage pipe should stand upright on the cement or brick floor, leaving an outlet at the bottom.
Chicken manure can be mixed with fruit waste, vegetable waste, root feed, etc. for silage or alone with molasses for silage. If the amount of soluble carbohydrates in the dietary ingredients is insufficient, molasses () or other sources of fermentable carbohydrates must be added. .
Silage is a simple method that not only prevents the loss of crude protein, but also converts part of the available non-protein nitrogen into protein-bound nitrogen (true protein).
The fermentation process takes about three days to complete, but it is best to use three days of silage for feeding.
Drying in the chicken house
Lay moisture-absorbing materials in the chicken house to enhance ventilation and promote natural drying. This method is simple, easy and low-cost, but takes a long time.
How to feed chicken manure to pigs
Feed pigs with fresh chicken manure
In Southeast Asian countries, chickens and pigs are raised in the same pen. The chicken cage is placed . If it is licked clean by a pig within an hour, it can save about 3% of feed, usually one chicken for one pig.
Liu Chuanxiang, a professional farmer in Beijipo Town, Tai'an City, feeds pigs with fresh chicken manure. The pig manure goes to fruit trees and receives good economic benefits. She mixes /3 compound feed with /3 fresh chicken manure (dried) to feed the fattening pigs.
If an epidemic is spreading, use is suspended.
Feeding growing and fattening pigs with processed chicken manure
A large number of experiments at home and abroad have shown that the basic diet + 3 chicken manure recycled feed, fed in unlimited amounts, compared with the control group fed completely the basic diet, Their average daily weight gain is very close, and each head can save 1,000 kilograms of feed (test results of our school).
If the proportion of chicken manure in the diet is increased, such as adding it to the above, molasses, sugar residue, sub-powder or oil must be added to supplement the energy deficiency.
Feeding pregnant sows with fermented chicken manure
Professor Zhang Heliang and others have achieved good results by adding fermented chicken manure to the diet of pregnant sows. Lower costs than the control group without adding chicken manure.
The ratio () is as follows: fermented chicken manure., corn., bean cake., wheat bran., salt. multi-dimensional.
The test results also show that fermented chicken manure can increase weight gain during pregnancy. With the increase in the amount of fermented chicken manure added, the lactation capacity (litter weight at age) of sows has a tendency to gradually increase. The reason may be that fermented chicken manure not only increases the content of crude protein, total amino acids and pig essential amino acids, but is also rich in vitamin B, various enzymes and various acids, alcohols and other aromatic stimulating substances, which can significantly improve the sows' health. digestive and nutritional status.
The author suggests that fermented chicken manure can be added to sows waiting to be bred, and fermented chicken manure can be added to lactating sows.
, The impact of feeding chicken manure to pigs on meat quality, pig parasites and intestinal microecology
According to experimental research in our school, feeding chicken manure to pigs has an impact on the sensory quality and eating quality of meat. There are no obvious adverse effects on a number of physical and chemical properties, such as the color, storage stability, tenderness and content of various amino acids, especially the essential amino acids for the human body, and other quality traits of the meat after feeding pigs with different proportions of chicken manure. ), after chicken manure is fed to pigs, only the elastic hardness of the meat is slightly higher and the content of glutamic acid and aspartic acid is slightly lower, but they are all within the normal range. There is no peculiar smell in the taste and no adverse effects on the meat quality and flavor. Experiments have proven that feeding chicken manure to pigs will not cause the spread of livestock and poultry diseases and parasite infections, and the microecological environment in the intestines of pigs will not change. At the same time, the amount of B and B residues in the meat of pigs fed chicken manure is not significantly different from that of other pork. , and far below the standards of food hygiene regulations, making it safe and reliable to eat.
