CATDOLL : CATDOLL: What are the functions and uses of earthworms?

1. What are the functions and uses of earthworms?

The functions and uses of earthworms are as follows:

1. Earthworms are rich in nutrients and can be made into earthworms, or used as high-protein food and feed.

2. Earthworms dig holes to loosen the soil and decompose organic matter, creating good conditions for the growth and reproduction of soil microorganisms. They play a special role in soil improvement, pollution elimination, ecological environment protection, material circulation, biodiversity, etc. Currently, many countries use earthworms to treat domestic garbage, organic waste and purify sewage.

Activity habits:

Generally speaking, the activity temperature of earthworms is 5-30℃, they enter a dormant state at 0-5℃ and die below 0℃. The optimum temperature is around 20-27℃, which is also the optimum temperature for earthworm cocoon eggs. They stop growing at above 32℃ and die at above 40℃.

Earthworms use their skin to breathe, so their bodies must remain moist. Water accounts for more than 75% of their body weight. Preventing water loss is the key to their survival. Therefore, the humidity of the feed should be kept at around 70%.

Earthworms grow best in a pH range of 6-8 and produce the most cocoons.

Earthworms have high levels of unsaturated fatty acids and low levels of saturated fatty acids, especially linoleic acid, which has anti-cancer, blood pressure-lowering, and beauty-enhancing effects. They are very suitable for the nutritional fashion pursued by modern people, and they also have unique tridecanoids that are different from other animals. Earthworms raised with agricultural and sideline products as feed can be used as a high-nutrition and safe food resource.

Additional information:

The properties of earthworms that improve soil quality.

Earthworms swallow a lot of soil every day, grind it in the stomach, and digest it with enzymes in the intestines. Only 5% to 10% of the ingested soil is absorbed, and the rest is excreted in the form of ecological soil, which is rich in trace elements such as N, P, K and soil probiotics (nitrogen-fixing bacteria and edible mycorrhizal fungi, etc.).

Earthworms can humify organic matter in their intestines, converting large amounts of organic particles into complex amorphous colloids containing phenolic substances. About 1/4 of the organic matter is converted into humus, which can be used as a slow-release fertilizer in the soil.

During the bioremediation of soil, the number of earthworms increases significantly, which can improve soil quality in many ways. Earthworms accelerate soil fragmentation and aeration, and can turn the soil over and redisperse it.

2. What contributions do earthworms make to mankind?

Nutritional Value

The earthworm self-solution is obtained by using the earthworm's own enzyme system to autolyze under certain conditions. The extraction rate is generally above 75%, with protein accounting for 56%-65% of the dry weight and free amino acid content of 50-70g/L. It contains 10 essential amino acids for the human body. The above indicators are higher than soy protein. The unsaturated fatty acid content in earthworms is high and the saturated fatty acid content is low. In particular, the content of linoleic acid, which has anti-cancer, blood pressure lowering, arteriosclerosis prevention, and beauty-enhancing effects, is higher. It is very suitable for the nutritional fashion pursued by modern people. It also has a unique tridecancarboxylic acid that is different from other animals. Earthworms raised with agricultural and sideline products as feed can be used as a high-nutrition and safe food resource.

Medicinal value

Earthworms contain earthworm essence, various amino acids, vitamins, etc., and have been used as medicine since ancient times.

Economic Value

Earthworms move through the soil and eat it, which can loosen the soil and improve its physical and chemical properties. The soil that passes through the digestive tract of earthworms is excreted as earthworm castings, which contain nitrogen, phosphorus and potassium several times higher than ordinary soil, and is a highly effective organic fertilizer.

Improving soil is the greatest contribution of earthworms to mankind.

Earthworms move in the soil, making the soil loose, allowing more air and water to penetrate into the soil, which is beneficial to plant growth and can improve the soil. The feces they excrete are rich in nutrients such as nitrogen, phosphorus and potassium, which can improve soil fertility. Their bodies contain a lot of protein and fat and have high nutritional value, making them excellent feed and food. They can also be used to process organic waste.

The earthworm is an animal. Its greatest contribution is that it can loosen the soil. For people to grow plants, it can provide an ideal level of positive help. Therefore, we must treat animals with care and get along with them in a friendly manner, so that we can better cherish and love nature.

I don't think I've made any contribution. Apart from making medicine, I don't think I've made any other contribution.

3. What are the benefits of eating earthworms?

Earthworms can produce a variety of traditional Chinese medicines

Western medicine

Medicines for humans and animals, earthworm injection, Puenfu, thrombolytic, Bio, antithrombotic, Buchang capsules.

Earthworms can be used as bait for various poultry, livestock, fishery products, aquatic pet food, animal live food, and feed additives and attractants.

Dried earthworms can be used as high-end bait for various fish and aquatic products.

Fresh earthworms are high-protein live bait. For livestock and poultry, eating earthworms for a long time can reduce the amount of medicine used and reduce mortality.

Frozen earthworms are a high-efficiency medicinal bait. Various livestock and poultry can eat earthworms for a long time to improve the quality of meat, eggs and milk and reduce drug residues.

Freeze-dried earthworms are high-nutrition floating bait for aquatic products. Fish fry farms and aquaculture farms that eat earthworms regularly will make their fry strong, healthy and colorful.

Earthworms - have diuretic, analgesic, antiasthmatic, antihypertensive, antipyretic, anticonvulsant and other effects.

Earthworms-contain earthworm elements, earthworm antipyretic elements, vitamin B complex and other ingredients.

Earthworms - can be used to extract biopharmaceuticals such as protease, lumbrokinase, and earthworm fibrinolytic enzyme.

According to measurements, the protein content of earthworms is about 53.5% to 65.1% of dry weight, the fat content is about 4.4% to 17.38%, the carbohydrate content is about 11% to 17.4%, and the ash content is 7.8% to 23%. Earthworms are also rich in vitamin D (about 0.04% to 0.073% of fresh weight), as well as mineral elements such as calcium and phosphorus (about 0.124% to 0.188% of fresh weight). Earthworms contain a variety of medicinal ingredients such as earthworms, earthworm detoxification, xanthine, antihistamines and vitamin B. At the same time, earthworms are also intermediate hosts for some parasites such as nematodes and tapeworms, such as the roundworm and the long-spined roundworm.

Although earthworms contain many substances that are beneficial to humans, there are some rules for eating them.
