It is very difficult to change the dietary structure of the people of our country to meat-based foods using traditional methods of feeding. Even the current trend of increasing meat production year by year will stagnate. However, depending on advances in science and technology, a wide range of sources of feed, especially one-time use of feeds, can be reused repeatedly to increase feed production, ensure quality, and promote the development of livestock husbandry. Within, changing our country's dietary structure. The necessity of recycling such as the daily consumption of fish, meat, eggs and 0.5 kg per person as the standard of our country's diet will require 183 kg per year, which is more than three times the present, and the country needs 216 million tons annually. Among them, the production of cattle, rabbits, and rabbits with aquatic products and herbivores is expected to reach 1/4 of the total, and the remaining 138 kg will be exchanged for feed. According to the current feed level, more than 410 kilograms of grain are needed, but in a relatively long period of time, China’s per capita grain output can only hover around 400 kilograms. Even if we reach meat-based foods, we still need 0.25 kg of rations per day, 91 kg for the whole year, and deduct about 100 kg of industrial grain per capita. There are only 210 kg of feed grain, and there is a shortage of more than 200 million tons in the country. Gaps cannot be filled by imports or farmland production. The use of 210 kg of feed to produce 138 kilograms of meat, eggs, meat and meat ratio needs to be increased to 1.52:1, so that high feed remuneration is difficult to achieve due to the raising of feeding technology. Moreover, the handling of animal manure is also a big problem. In the past, excrement was used for fertillation. Now, due to the development of chemical fertilizers and the increase in the wages of farming, the farmers’ interest in using manure as fertilizer is getting lower and lower. Together with the large-scale development of farms, the cost of excreta disposal and returning to farmland has become a major burden on the farms, resulting in a large loss of excreta and serious environmental pollution. The above shows that the development of the traditional breeding industry is difficult to overcome the two major difficulties of feed shortage and waste and urine disposal. However, once the efficient use of excreta resources is resolved, it is not difficult to overcome the two difficulties. The possibility of recycling Starch and fat in the feed are partially converted into fat in the animal body, and most of them are oxidized to generate energy and decomposed into carbon dioxide and water, which may cause loss of reuse. Proteins are different. Some of them are converted into meat and eggs. Most of them are metabolized into urea and enter excreta. Urease secretes urease, which decomposes urea into carbon dioxide and ammonia, and then uses ammonia and fungus degradation products. It grows and reproduces and synthesizes bacterial proteins, which become new protein feeds as soon as they are solidified or absorbed. In nature, this protein has long been used, such as chickens, dogs, insects, human feces, chicken manure to feed pigs, pigs and cow dung to fish. Due to the consumption of starch and so on, the crude protein in the feces is relatively concentrated, and the content is relatively high. For example, the content of crude protein in dry chicken manure reaches 20% to 30%. Therefore, it is entirely feasible to use fecal feed on a large scale as long as the harmful components in the feces are removed or the protein is extracted from the feces. Several ways to compare the use of manure as feed methods are: fresh manure directly fed; made of manure feed; use insects to purify high protein. Feeding fresh manure directly is not easy to do well in feeding operations, storage and transportation, etc. The feed value is also affected by the health status of the manure-producing animal and it is difficult to implement it on a large scale. The use of mechanical equipment to process the dung into dry feed requires the collection and transportation of fresh dung, dehydration, drying, sterilization, and elimination of sundries. The processing costs are high, the energy consumption is high, the feed quality is poor, and it is difficult to feed alone. Processing of chicken feces and human feces with high crude protein content can also have certain economic benefits, and the value of processing pigs and cow dung is not significant. Therefore, the better method is to use insects to extract high protein from feces, eat feces from faecal insects, and collect the parasites for feed. Among them, the most valuable ones are the flies. The fly maggots are suitable for living in the dung, and their fertility is extremely strong. A pair of flies can breed more than 200 billion in a breeding season. The maggots are never sick and have a short growth cycle and are easy to raise. The fly's recipes include various feces and food waste. Carcasses are rich in nutrients. The content of crude protein and crude fat in loquat powder is as high as 80% or more, which is higher than fish meal. It is the best feed for livestock and poultry. Therefore, raising maggots is one of the best forms of manure feed. Efficient breeding of oysters is easy and effective. China's use of fly maggots is very early. Chinese medicine “swollen worms” are brewed by collecting maggots. It is a good medicine for the treatment of diseases before the invention of antibiotics. In the past, rural areas in Jiangsu Province had a habit of fishing for ducks, and the benefits were very good. In foreign countries will also solve the problem of shortage of human high-protein foods in raising oysters, dedicated to the study of worms and human food. Since the 1980s, China's breeding industry has flourished, but it has not been able to achieve widespread popularization due to the effects of dirty odors and fly-killing. To turn flies from pests into beneficial insects for artificial breeding, there must be a closed solar greenhouse plant and unmanned automated assembly line equipment. The breeding farm is equipped with such a breeding farm, which can form a closed cycle of livestock manure, manure fly larvae, and quail feeding livestock on the farm and become a dung-free farm. In the excrement-free farm, the protein in the feed can be reused repeatedly and the production of meat and eggs can be greatly improved. For example, when one ton of compound feed with a crude protein content of 24% is used to feed chickens, when the feed to meat ratio is 3:1, the chicken gains weight or produces 330 kilograms, contains about 100 kilograms of protein, and the remaining 140 kilograms of crude protein enters about 2 tons. In wet manure, 500 kilograms of fresh squid can be produced for raising oysters. Fresh quail chickens can produce 1 kilogram of eggs for every 1.5 kilograms, which means they get 330 kilograms of eggs. There are more than 30 kg of crude protein into the feces. It can produce 150 kilograms of eggs and change 100 kilograms of eggs, so that the cycle will continue to increase the total output of meat and eggs by more than double the time of one-time use of feed, and it will also save the cost of controlling the excrement. The enclosure of the raising plant can be used as window, window and wall, and then sealed with plastic film or glass at the periphery to form a solar-power greenhouse plant with greenhouses, which can be produced all year round. The automated production line for raising cockroaches also has Chinese patents. The cost of plant and equipment for raising a loquat plant is lower than that of a biogas plant or a biogas digester that handles excrement excrement. The profit value of the plant is high, and the plant investment can be recovered after about one year of operation. People need to have enough meat to change their dietary structure, and the price must be compatible with people's consumption ability. Raising can make 56 percent of the crude protein needed by livestock to be obtained from the dung produced by the people and can be greatly reduced. Feeding costs.
