The method of raising earthworms with pig manure

Pig manure is originally a metabolic waste of pigs, many people do not know its use, in fact, pig manure still has many uses, it can turn waste into treasure. Raising earthworms with pig manure is a good example. It can not only create the breeding wealth of earthworms, but also give full play to the value of pig manure.

The method of raising earthworms with pig manure

First of all, the pond for raising earthworms has no bottom, because the bottom will affect the growth of earthworms. This is because earthworms like to live in moist soil, and the environment is better breathable. The cement pool is directly grounded without making a bottom, and the water surface can be adjusted during drought and waterlogging to ensure air permeability.

Secondly, pig manure cannot be fed directly to earthworms. When the earthworms were first introduced, Lao du put the worms in the pond and began to throw pig dung. When I saw it the next morning, the earthworms escaped. A friend who raised earthworms told him that his problem probably lies in the pig manure fed to the earthworms. Other people use cow dung to raise earthworms. What's the difference between pig manure and cow dung?

It turns out that the smell of ammonia in pig manure is relatively heavy, which has something to do with the feed the pigs eat. Pigs usually eat concentrate feed, which is high in protein and easy to produce ammonia smell. Especially for fattening pigs, a large amount of corn and soybean meal were added to the feed, and when the pigs could not be digested, the smell of ammonia in the feces was even heavier, which smoked the earthworms away. On the contrary, cattle eat very little concentrate, most of them are forage, and the indigestible forage will be excreted with the feces, so the smell of cow feces will be lighter.

In fact, pigs eat fine, there are many nutrients left in the feces, which should be a good thing for raising earthworms, but the smell is too big for earthworms to bear. Lao du remembered that there was a difference between the feed for the sow and the feed for the fattening pig, because there was a lot of crude fiber in the sow feed. Because in order to prevent sow constipation during production, the protein content in the feed should not be too high, but need to add more crude fiber, so the smell of ammonia in sow feces will be lighter.

As a result, Lao du and the workers mixed sow manure and fat pig manure together to dry and ferment. After a period of drying, the smell of ammonia in pig manure almost dissipated. However, in the release of pig manure, Lao du also learned a lesson and switched to sub-point delivery, so that earthworms slowly adapt to pig manure. First ferment pig manure, and then put it in piles, this method meets the living conditions of earthworms, and they settle down in Lao du's pig farm. However, this is just the beginning, and earthworms have to be allowed to reproduce in order to provide more protein feed for pig farms. Lao du thought that after the first batch of earthworms were propagated, we should not rush to use them, let them breed a few more batches, and then concentrate on using them. However, something unexpected happened to him, and many earthworms ran away again, and all of them ran away.

The environment where earthworms like to live

The first is humidity. An earthworm likes a wet environment because 80% of its body is water, and it is especially easy to lose water if the environment is too dry. Therefore, if the humidity of the place where you live is not suitable, the earthworm will run. In order to keep the soil in a proper state of humidity, pig farm workers often sprinkle water into the earthworm pond. The temperature is high in summer and the water evaporates quickly, so workers should pay more attention to sprinkling water into the earthworm pool in summer to create a humid environment for earthworms. Because he was raised outdoors, Lao du was afraid that earthworms would not survive the winter. At the beginning of winter, Lao du asked the workers to cover the pond with corn straw. As soon as the corn straw is spread, it is tantamount to covering the earthworm pond with a thick quilt, which plays a role in preventing cold and heat preservation.

If there is nothing wrong with the temperature and humidity, earthworms have been living well. Under the guidance of his friend, Lao du finally figured it out. It turns out that earthworms have a habit of cohabiting with the same generation. if mother and son live together, the older ones will move away. Earthworms have strong reproductive ability and grow very fast. General mature earthworms begin to lay eggs a week after mating, and small earthworms can hatch in about 20 days. After just two months of growth, small earthworms can reach sexual maturity and mate and lay eggs. In this way, the relationship in the pool is more complicated, and the mother and offspring all live together.

Therefore, if you want to prevent earthworms from escaping, you have to breed and harvest one batch, and harvest the large earthworms in time. The collected earthworms are made into dried earthworms, which are processed into powder and become very good protein feed for pigs. In the past, in Lao du's pig farm, the added animal protein feed was fish meal, which was about 2%. Although the proportion was not high, because the price of fish meal was very high, for a farm like Lao du, which had thousands of pigs, it was not a small expense.

The protein content of earthworms is very high, and the protein content of sun-dried earthworms is even higher than that of fish meal, which can be added to feed instead of fish meal, and the vitamins and trace elements contained in earthworms are also good for the growth of pigs. Therefore, feeding pigs with earthworms instead of fish meal can not only help pigs grow, but also save money. By raising earthworms, Lao du not only treated pig manure, but also obtained high-protein feed, which can be said to kill two birds with one stone.

The role of pig manure

1. As fertilizer

2. Drying as feed and feeding cattle, sheep and chickens with a small share.

3. Make biogas.

4. Pig manure fish culture: after the fish pond is cleaned, 250-300 kg of pig manure per mu of water is applied, topdressing once every 10 days, and 50 kg of pig manure each time.

5. After the pig manure is fermented, it is put into the maggot pond of the maggot room to raise maggots.

6. Pig manure can be used to raise earthworms, collect and accumulate fresh pig manure, spread out each pile to 70% dry, then participate in 20% of the soil, 3% of wheat bran and rice bran, seal the dung with plastic film, and ferment pig manure in about 7 days. Then spread the fermented pig manure flat in the pit, cover it with grass or grass curtains and keep it moist for about 20 days.

Market Prospect of Earthworm Culture

The rise of earthworm farming has not only opened up a new source of animal protein feed for the development of livestock, poultry and aquaculture, but also found a new way for cities to purify the environment and deal with public hazards, and with the in-depth study of the physiochemistry of earthworms, it can also provide valuable raw materials for food, medicine and other industries. Therefore, the prospect of earthworm breeding is broad.

1. Earthworms can be used as pharmaceuticals. At present, the international market costs 8-150000 yuan per ton of dried earthworms, or even higher. According to analysis, earthworms contain a variety of medicinal ingredients, such as earthworm, earthworm antipyretic hormone, earthworm toxin, Huang Chuyin, antihistamine, choline, cholesterol, nucleic acid derivatives, B vitamins and so on. At present, lumbrokinase can be scientifically extracted from earthworms for the treatment of cerebral infarction and other diseases, and lumbrokinase oral or injection has been put on the market. Experiments have proved that earthworms can be used for clinical treatment.

2. Earthworms are known as the best protein feed in the world, which is rich in nutritional value. Earthworms contain 18 kinds of amino acids, minerals and vitamins. Therefore, earthworms can be used to cultivate aquatic products such as Loach and Monopterus Albus, which is helpful to increase the production of aquatic products. Earthworms can also be used to raise pigs, chickens and other poultry to improve their own nutritional value. Earthworms can also be made into earthworm powder as a growth agent for pigs. Raising pigs, chickens, ducks, rice field eel and Loach with earthworms not only grows fast and has good meat quality, but also costs less money.

3. Earthworms can also deal with municipal waste, purify the environment and accumulate fertilizers, which solves the problem of garbage disposal in various urban areas. Thus it can be seen that breeding earthworms is a good way to get rich. The work of raising earthworms is not large, and one person can manage about 3-4 mu of land. It is suggested that the majority of farmers can use their spare time to develop earthworm breeding, which not only increases income for families, but also improves social benefits.

It can be seen that raising earthworms with pig manure is a good way to turn waste into treasure. in fact, before raising earthworms, we should fully understand the living environment and living habits of earthworms in order to better cultivate earthworms. Do not underestimate the humble earthworm, in fact, it has many uses, the market demand is also very large, it can also create great wealth.
