Earthworms are used as feed, and what are the earthworm feeds

Earthworm. It is a high-quality protein feed, but it is often accompanied by a smell that is difficult to remove, because livestock and poultry are reluctant to eat, and it is difficult to promote. In recent years, a new process for producing odorless earthworm feed has been introduced, which is worth referencing.

The production principle of odorless earthworm feed is that the oil is put into the container and heated, and the earthworm raw materials are put into the high-temperature oil, and the protein is dehydrated and the thermal coagulation phenomenon occurs when the container pressure is low. Then the oil is separated, and then the residual oil is extracted with a solvent, and the earthworms are separated, and the seasoning product is obtained after crushing.

For specific implementation, first put 1,000 liters of animal oil or vegetable oil, palm oil.

Wait until it is packed into a container with a cubic centimeter volume of stirring slurry and heat to about 120. 2,000 kilograms of earthworm raw materials with no moisture on the surface were then fused, and the air inside the container was extracted to reduce the pressure to 660 mm Hg. At the same time, the temperature of the raw material is maintained at about 90 for 15 minutes.

Through the action of high hot oil temperature, the earthworm in the oil is evenly heated, the water in the body is removed, and the water content is reduced to about 6, while the animal glue and other proteins in the body produce thermal coagulation and hydrogen sulfide.

Methyl mercaptan, trimethylamine.

Odorous components such as carbon-based compounds and ammonia are volatilized and removed. In this process, various amino acids within the earthworm.

Nutrients such as inosinate and guanylate are still properly preserved and are eventually destroyed.

The raw material is taken out of the heating container, the oil is separated by pressing until the oil content reaches about 8, and the residual oil is extracted with n-hexane. The resulting solid substance is crushed to become a odorless high protein.

Fodder. It should be noted that if there is water attached to the surface of the earthworm, the temperature is too high, and the heating time is too long, the animal glue in the earthworm will dissolve into the water, making it difficult for the oil to be pressed and separated.

Compared with the external heating and drying method used in the past, the advantage of this method is that the protein is not soluble in water or oil, and its quality is not affected. The protein content of the resulting earthworm feed increased due to no loss12 14, the ammonia concentration decreased to about the original level, and the odor was almost completely eliminated.

<> animal feed: mainly including cow manure, pig manure, horse manure, sheep manure, duck manure, chicken manure, rabbit manure, etc.

Plant-based feed: mainly including straw, corn straw, wheat straw and other crop straws.

Garbage feed: mainly including all kinds of rotten fruits and vegetables, leftovers, livestock scraps, wine troughs, bagasse, etc.

1. Common earthworm feed

1. Animal feed.

It mainly includes cow manure, pig manure, chicken manure, duck manure, horse manure, sheep manure, rabbit manure and other livestock manure, among which chicken manure, duck manure, sheep manure, rabbit manure belongs to nitrogen feed, and the proportion of preparation should not exceed a quarter of the manure.

2. Plant-based feed.

It mainly includes rice straw, corn straw, wheat straw, peanut vine and various fallen leaves, tree roots, rotten wood, rotten grass, etc.

3. Garbage feed.

1) Domestic garbage: mainly including rotten vegetable leaves, rotten fruits, fruit peels, leftovers and scraps of various poultry and fish.

2) Food industry by-products: mainly including wine tanks, bagasse, filter sludge, sauce residue, etc.

3) Agricultural and sideline product scraps: mainly including rice bran, bran, peanut bran, soybean cake, pomace, edible fungus cultivation materials, etc.

2. Common earthworm feed formula

1. Formula 1: 50% cow manure, 50% pulp sludge.

2. Formula 2: 60% cow manure and 40% crop straw.

3. Formula 3: 20% cow manure, 20% pig manure, 20% chicken manure, and 40% straw.

4. Formula 4: 70% pig manure, 30% straw.

5. Closed and rolled formula five: 70% organic waste, 20% livestock manure, and 10% peel and vegetable scraps.

6. Formula 6: 60% pig manure, 40% bagasse.

7. In the above feed formula, an appropriate amount of bran or rice bran, soybean cake and peanut bran can be added to increase the nutrition of the feed. In addition, the feed needs to be fermented before it can be used for feeding, and it is not suitable to be fed directly with fresh feed.

1. Put 1000 liters of animal oil or vegetable oil, palm oil, etc. into a container with a cubic centimeter volume of stirring slurry, and heat it to about 120 degrees Celsius.

2. Put 2000 kg of earthworm raw materials with no moisture on the surface of the empty grinding machine, and extract the air in the container to reduce the pressure to 660 mm Hg.

3. Stir for 15 minutes at the temperature of the raw material at about 90 degrees Celsius.

4. Take out the raw materials from the heating container, separate the oil by pressing until the oil content reaches about 8%, and then use n-hexane to extract the residual oil.

5. The obtained solid substance can be crushed.

Earthworms are omnivores, and can be fed with various livestock manure, melon peels, leaves, vegetable leaves, non-toxic household garbage and other substances when breeding, but they must be fermented and rotted before feeding. If earthworms are fed unfermented and rotted organic feed, the earthworms will generally refuse to eat, and after a period of time, the feed will ferment naturally, and the resulting high temperatures and the release of harmful gases will cause a large number of earthworms to die.

1. What feed do earthworms feed?

1. Feed type.

Earthworm is an omnivore, all kinds of livestock manure, melon peel, leaves, vegetable leaves, non-toxic household garbage and other substances can be used as their feed, but before feeding, it must be fermented and rotted to reach the degree of odorless, sour, and brown appearance before feeding.

2. Precautions for feeding earthworms.

1) Organic matter must be fully fermented and decomposed to make it fine, soft, rotten, rich in nutrients, easy to digest, and good palatability. If the feed is fed directly without decay, the earthworms will usually refuse to eat, and after a period of time, the feed will ferment naturally, and the resulting high temperature (generally up to 60-80 °C) and the release of harmful gases (such as ammonia, methane) will cause a large number of earthworms to die.

2) If you want to feed livestock manure (such as rabbit manure, chicken manure), it must be fermented and rotted before it can be used, because this kind of manure contains a large amount of egg white matter and nitrogen, otherwise the natural fermentation will be more serious.

2. Earthworm feeding methods

1. Ordinary feeding.

1) Prepare a large container, put three-quarters of the fertile soil in it, then sprinkle an appropriate amount of water to water the soil, and put in a few vegetable leaves.

2) Put the earthworms in a container and cover with a damp cloth to keep the soil moist.

2. Large-scale feeding.

1) Choose a place with high terrain (dry and ventilated), good drainage, no pollution and no disturbance as the breeding site, and then use tools to dig a shallow pit with a width of about 1 meter, a depth of about 25 cm and an appropriate length, and the bottom of the pit is required to be relatively flat.

2) The bottom of the pit and the four walls are built with bricks to prevent the earthworms from escaping, and then a layer of feed with a thickness of about 5 cm can be put into the earthworms.

3) Earthworms are not resistant to high temperatures above 35 °C, nor are they resistant to low temperatures below 0 °C, so shade sheds should be built on the breeding pit in summer, and simple plastic sheds should be built on the breeding pit in winter, so as to reduce or increase the temperature of the pit, so that the earthworms can safely spend summer or winter.

4) During the feeding period, protection should be done to avoid earthworms from being attacked by natural enemies such as rats, frogs, and snakes.
