2. Breeding platform. Build by laying bricks or stones into a platform with a slope of 10cm. Smooth the platform with cement. Mature maggots are used to crawling to high places.
3. Production process:
(1) Formula of manure:
Raw materials for maggot breeding: 80% fresh pig manure 10% wheat bran 10% peanut residue.
(Note: spraying water with EM 1: 10 every day can deodorize)
Raw materials for egg collection: 80% fresh pig manure 10% wheat bran.
9.5% peanut and 0.5% ammonium bicarbonate
Flying drink: 5% yellow sugar 5% milk powder 5% fresh eggs.
0.2% vitamin C 0.2% methionine 84.6% water
② fecal fermentation:
Dilute and ferment with EM according to the ratio of 1: 10. The humidity is 70-80%, and it can be used after mixed fermentation for 1-2 days, which can eliminate toxic and harmful gases in the process of raising maggots.
(3) The raw materials for collecting eggs are placed on the feces of the fly maggot breeding platform. Two days later, young maggots can be seen the next day, and mature maggots can be seen crawling out of the dung heap and climbing to the slightly higher side of the platform. Take it out and rinse it with 1/5000 potassium permanganate solution 10 minute.
④ Timing of feeding, collecting fly eggs and taking maggots.
Feeding (flying drink): from time to time, after observing eating, be careful not to feed too much at a time to prevent weakness and death.
Raw materials for collecting eggs: put them in cages in the morning, and take them out at night and put them in maggot breeding tables.
Depends on production and application.
According to this method, each cage can produce 20 kilograms of fly maggots every day. Each batch of manure raw materials can produce a batch of maggots, which can then be used to cultivate earthworms. In the temperature range suitable for the growth of maggots, the temperature affects the time when maggots appear. Therefore, the production plan should be adjusted at any time according to the temperature change to ensure the stable and balanced supply of fresh fly maggots.
Benefit analysis of fly maggot culture
Among many insects, people first turned their attention to the reproduction of fly maggots, which is determined by the characteristics of fly groups that other insects do not have:
(a) Rapid replication and high production efficiency
The self-worth of flies is fast. It is estimated that L can breed 20 billion groups of flies in 4 months and accumulate more than 600 tons of pure protein. Generally, maggots only need IO ~ 1 1d to develop from eggs to adults. It takes only 4 ~ 5 hills from egg to adult, with short cycle, fast reproduction and high yield. The newly hatched larvae are 0. After growing at 24 ~ 30℃ for 4 ~ SD, the weight of fly maggots can reach 20 ~ 25 mg, and the total biomass is increased by 250～30o times. As a lower animal, although the assimilation efficiency of insects is about 0.5 times that of mammals, its production efficiency is 15 ~ 40 times that of mammals, which is unmatched by other methods for producing animal protein so far.
(two) omnivores and animal droppings
There are a wide range of raw materials for breeding fly maggots, such as wheat bran, rice bran, distiller's grains, bean dregs and other agricultural and sideline products, and pig manure, chicken manure and duck manure are all suitable for breeding. A livestock and poultry farm with a sister fly farm is equivalent to building an insect feed production plant on the protein. The raw material is feces discharged by livestock and poultry, and the product is high-quality fly sister protein. Give priority to waste and turn harm into benefit. The excrement after breeding maggots is tasteless, does not attract flies, and is fertile and loose. It is a high-quality organic fertilizer for crops. This special transformation function is beyond the reach of other feed insects. Fei Jie's ability to treat livestock manure is 20 times that of stealing insects.
(3) Strong disease resistance and less morbidity.
Flies haunt dirty places and come into contact with countless germs, but they can be safe and sound and will not be infected by these germs. Maggots have a strong vitality. They never get sick when they eat feces, and there is nothing poisonous in their bodies. The kitchen environment that other animals can't stand is a paradise for maggots, thanks to its excellent immune function. Flies can produce a variety of effective substances against bacteria and viruses. For example, there is an antibacterial active protein in the secretion of flies, which has strong bactericidal and antiviral abilities. As long as the concentration is one ten thousandth, it can kill all kinds of bacteria and viruses. No modern antibiotic can compare with it. Scientists have also found an anticancer active protein in flies, which has a strong inhibitory effect on cancer cells. Breeding maggots generally does not need to worry about disease prevention, which can greatly save the cost of disease prevention.
(4) High quality animal protein feed
The research results at home and abroad show that not only the protein content of insects is higher than the protein content of chickens, fish, eggs, pork and other higher animals, but also the amino acid composition of protein is very reasonable, which is close to the protein amino acid ratio model formulated by FAO. The digestibility of insect protein is very close to or better than that of animal protein. Therefore, insect protein can be used as high-quality protein feed for livestock and poultry.
At present, many countries in the world regard artificial rearing of insects as the main direction to solve the source of protein feed. Generally speaking, Dried Flying Sister contains about 60% of protein, 65,438+00% ~ 65,438+05% of fat, and is also rich in various amino acids, of which the total amount of essential amino acids is 2.3 times that of fish meal, and methionine and lysine are 2.7 times and 26 times that of fish meal respectively, which is obviously Gao Qian fish meal. Practice has proved that it can not only completely replace fish meal, but also add a proper amount of live flies to feed crabs, fish, turtles, eels, eels, birds and so on. And the growth is obviously accelerated, the output is obviously improved, and the effect is very good. According to the experiment, adding a proper amount of fresh food to the feed of laying hens can increase the laying rate 17% ~ 25%, increase the yield when feeding fish by more than 22%, increase the growth rate of feeding pigs by 19.2% ~ 42%, and save the feed ZO% ~ 4O%. Artificial breeding of fly maggots can alleviate the shortage of feed and reduce the feeding cost. In this way, the pressure of feed grain on China's agriculture, the pressure on the environment, the pressure on cultivated land and irrigation water, and the foreign exchange pressure on imported grain can be greatly alleviated.
(5) Fly maggots are full of treasures.
Fly maggot protein can not only be used as high-quality protein feed, but also extract protein powder to develop advanced nutrition, which is an ideal nutritional source for human beings in the future. A variety of biochemical products such as fat, antibiotics and lectin can be obtained at the same time in the production process. Antibacterial protein can destroy all fungal microorganisms and has a strong bactericidal effect. Fly maggot shell is a good raw material for extracting chitin, which is regarded as the sixth essential factor for human life besides sugar, protein, fat, vitamins and minerals. Chitin has unique medical and health care functions for human body, such as activating and repairing cells, enhancing immune regulation, preventing diseases, improving disease resistance and accelerating rehabilitation, removing toxic and harmful substances in vitro, and regulating human physiological balance.
(6) The production of fly maggots is simple and easy.
The production of fly maggots does not need any epidemic prevention measures or modern workshops, and can be produced on a large scale under the conditions of heat preservation, manure supply and escape prevention of civil hydropower equipment. It does not produce toxic substances and does not pollute the environment. Fly maggots can be regarded as excellent chemical engineers. According to the current level of human science and technology, it is easy to cultivate fly maggots in factories. Fly maggots are resistant to high-density culture, a 50*50*50m? The fly cage can feed1~1.20 thousand adult flies. The large-scale and industrialized production technology of fly maggots and the preparation technology of biochemical products of fly maggots in China have gradually matured.
(7) Maggot dung is a high-quality organic fertilizer.
The excrement of livestock and poultry treated by fly maggots is not only tasteless, does not kill flies, but also fertile and loose, and is a high-quality organic fertilizer for crops. According to Russian reports, 500 kilograms of maggot dung can be obtained by treating its pig dung with flies. When treating pig manure with Fat Sister, the original weed seeds in pig manure are eaten by Fat Sister, and will not go back to the fields to harm crops. When manure is used as fertilizer, soil can get rid of the problems of soil hardening, physical properties deterioration and fertility decline caused by using chemical fertilizer. Under the condition of applying 20t clam manure on 1 hectare, the yield of oats was increased by 20% compared with that of applying full chemical fertilizer, while that of oats and beans was increased by 18% and 57% respectively. The yield of oats and beans is the most amazing, which is 68% higher than that of complete chemical fertilizer and 96% higher than that of phosphorus and potassium fertilizer, but the yield of potatoes is not significant.
(eight) an important part of ecological agriculture
Adding fly maggot culture to the material cycle of eco-agriculture can successfully solve the two major problems of fecal pollution and animal protein feed shortage. Only 25% of feed nutrients are digested and absorbed by livestock and poultry, and the rest is lost in feces, which is rich in nutrients such as protein. Fei Jie can digest and absorb almost all nutrients lost in feces and convert them into insect proteins. Other insects can't do it, but Fei Jie can take on the heavy responsibility. Increase the central industries other than aquaculture and planting, extend the food chain, and make the material energy change to a higher quality, which can be used by other higher animals, thus improving the utilization rate of resources. Waste is reused in the production process, and the output of one system is the input of another system, which forms a stable material virtuous cycle mechanism in the system and improves the stability and economic benefits of the system.
At present, almost all manure treatment technologies can only produce general organic fertilizer, and the removal is often incomplete, with large investment and high operating cost. Fly maggot bioengineering can produce antibacterial high-protein feed and bio-organic fertilizer at the same time, which has the advantages of fast treatment speed, high efficiency, low cost and thorough deodorization.
