The method of raising earthworms

Earthworms are arguably the best animal feed in the world. Of course, it is no secret that earthworms can be used to make traditional Chinese medicine and food, but even earthworm dung can be used as feed to feed chickens, ducks, pigs, fish and so on.

Section 1 Economic significance of Earthworm Culture

Earthworms contain a lot of protein, and the content of protein in dry matter can be as high as 70%. General analysis results can also get 41.62-66% crude protein.

According to the data, when 23% earthworm powder is added to the feed, the growth rate of pigs can be increased by more than 74,2%; the egg production of chickens can be increased by 1725%, and the growth rate can be accelerated by 30100%; the yield of soft-shelled turtle fed with fresh earthworms can be increased by 30% to more than 60%. Any other feed fed with fresh earthworms can not be compared and increased by 40%. When famous fish such as prawns, river crabs and eels were fed with earthworms, the yield increased by more than 30%, and the feed cost decreased by 4060%.

Section 2 living habits and ecological conditions of earthworms

This technique only focuses on the living habits and ecological conditions of Daping No. 3. The normal growth, development and reproduction of earthworms need suitable ecological conditions. The conditions required by different earthworms are also different.

1. Temperature

Generally speaking, the active temperature of earthworms is in the range of 530 ℃, 05 ℃ enters dormancy and dies below 0 ℃. The most suitable temperature is about 2027 ℃, which can grow, develop and reproduce well. It can maintain a certain growth at 2830 ℃, stop growing when it is more than 32 ℃, slow down when it is below 10 ℃, die when it is over 40 ℃, and the optimum hatching time for worm cocoons is 1827 ℃. It can be seen that the maximum lethal temperature of earthworms is lower than that of other invertebrates.

2. Humidity

Earthworms have no special respiratory organs, they use the skin to breathe, so the body of earthworms must be kept moist. If the earthworm is placed in a dry environment, the skin of the earthworm cannot remain moist after a period of time, so it cannot breathe normally. The earthworm will have spasms immediately and will die soon. Earthworms contain a large amount of water, accounting for more than 75% of their body weight, so preventing water loss is the key to earthworms' survival. The humidity of the feed is kept at about 60%.

3. PH (PH value)

Earthworm Daping 3 grows well in the range of PH 68 and produces the most cocoons in the range of PH 77.5.

4. Ventilation

Earthworms breathe on oxygen diffused into the soil by the atmosphere. The better the soil aeration, the more vigorous its metabolism. Not only there are many spawning cocoons, but also the mature period is shortened.

5. Food

Food is a long-term and key ecological factor affecting earthworms. Lack of food will lead to fierce competition among earthworms, resulting in decreased fecundity, spread of diseases and insect pests, increased mortality, escape of some earthworms and so on. The effect of food on earthworms is not only reflected in the quantity of food, but also reflected in the quality of food. Daping No. 3 earthworm feeds on animal dung.

The soilless aquaculture referred to in this technique actually refers to all the food of earthworms, replacing part of the soil that can not be used, and reducing a lot of restocking management. The whole culture box is full of food, so it can reduce competition and increase culture density.

6. Natural enemies and diseases

The natural enemies of earthworms include predatory and parasitic: predatory natural enemies are rats, birds, poultry, snakes, frogs, ants, mantis, spiders, centipedes, etc.; parasitic natural enemies are: parasites, parasitic flies, mites, leeches and so on.

Section 3 preparation and feeding of Feed

1. Types of feed

Daping No. 3 earthworm mainly feeds on cow dung, followed by pig manure. Any organic waste from livestock and poultry manure, brewing, sugar, food, paper and wood processing, such as distiller's grains, bagasse, sawdust, hemp knife, waste paper oars, edible mushroom dregs, etc.; garbage and domestic organic waste can be used as feed for earthworms.
