1. How to raise earthworms with cow dung

Technology of raising earthworms with fresh cow dung

Fresh cow dung can be used directly to raise earthworms without fermentation. If there are rotten fruits and vegetables, rotten leaves, etc., mixed with cow dung, the effect of raising earthworms will be better. First, pile the cow dung into a dung pile with a length of 2 meters, a width of 1 meter, and a height (thickness) of 35 cm. Use an iron rake to loosen the top cow dung every day. The thickness of the cow dung that is 50% dry needs to be loosened to about 5-8 cm. When it is about 50% dry, you can put earthworms in. Each pile of dung can be put into 30,000 egg-laying earthworms. Collect the earthworm manure and earthworm cocoons every 10 days and open another pile for incubation. Take the earthworm cocoons every 10 days and open another pile for incubation to ensure that the size and specifications of each batch of earthworms are consistent. During the breeding period, if the earthworm manure is found to be dry, spray EM water in time, and mix EM with clean water or rice washing water or rice soup in a ratio of 1:5 and spray it. Generally, spray it every 3-5 days. The earthworms raised by the above method grow fast and produce more and larger earthworm cocoons. Please note that poultry and livestock manure must be fermented with EM or dried and mixed to a moisture content of about 60% before it can be used to raise earthworms.

2. How to raise earthworms using raw cow dung?

Hello, this requires the use of a fermentation agent to ferment and decompose cow dung for breeding earthworms. I recommend that you use Lebefeng biological manure feed fermentation agent to ferment and decompose cow dung for breeding earthworms, which has high yield and good breeding effect.

It is suitable for the composting of organic materials such as livestock and poultry manure and straw. It is a high-quality and efficient microbial agent necessary for the production of manure feed and earthworm and maggot breeding.

In the process of breeding earthworms, the fermentation treatment of earthworm feed (poultry manure, distiller's grains, bagasse, leftover food, waste blood and animal offal, etc.) is a key. If the feed is not fermented or fermented incompletely, harmful gases will be produced. If the pH is too high or too low, the earthworms may escape, fail to produce cocoons or even die.

By using a second-fermenting agent to ferment manure, the fermentation time of manure is greatly shortened, the odor is reduced, and after the feed is fermented, the pH value will naturally reach 6.5-7.5, and it can be fed directly without adjustment. The feed utilization rate is greatly improved, the earthworms produce more cocoons, reproduce faster, and the yield is increased by 2-3 times.

How to do it:

1. Fermentation: Mix fresh cow dung and straw powder in a ratio of 2:1, and add the fermentation bacteria - second-rot agent. One bag of fermentation agent can ferment 1 to 2 tons of dung and pile it into large piles or strips for fermentation.

2. Turning the pile In the season with high temperature, the temperature in the pile will rise obviously on the first day, and it can rise to 60℃～70℃ in 4-5 days, and then gradually decrease. When the temperature in the pile drops to 40℃, turn the pile from top to bottom and from both sides to the middle. Turn the pile 2-3 times in winter and once in summer. The fermentation time is about 7-10 days for fermentation and decomposition to be completed, and the breeding effect is the best.

3. After the fermentation of the feed is finished, the feed can be used after being opened and watered to dissipate the heat. The top-adding method and side-feeding method are generally used for feeding. The top-adding method is to spread the feed on the original feed that has been eaten by earthworms, and it is done once every 10 to 15 days; the side-feeding method is to take out some of the eaten feed and add new feed on one side, and add the other side next time.

3. I heard that cow dung can be used to breed earthworms. I want to try it but I don’t know how to do it?

Yes, using Lebefeng manure fermentation agent to ferment cow dung to sterilize and deodorize it, and then breed earthworms, can effectively reduce earthworm mortality, increase earthworm reproduction rate, and increase production. Here I will introduce how to breed earthworms with cow dung:

1. Material preparation

After mixing cow dung (about 70%) with a certain proportion of straw powder, mushroom residue, peanut shell powder, or rice husk, sawdust, add Lebefeng manure fermentation agent at 0.3% of the weight of the material to be fermented (i.e. one kilogram ferments three tons of material) and mix evenly.

Use fresh rice bran (Note: "rice bran" is not "general bran". Rice bran has good nutrition and air permeability. Old rice bran or general bran has poor nutrition and is not good). Add 5 to 10 kilograms of rice bran to every kilogram of Lebefeng starter, which is conducive to mixing the starter and the material.

2. Moisture regulation

After the materials are prepared, the moisture content of the materials should be adjusted. When adjusting the moisture content, pay attention to adding a small amount at first. When it is close to the requirement (60% to 65%), add more slowly to prevent excessive humidity. If the moisture content exceeds the standard, add more dry materials to adjust. The method to judge whether the moisture content of the material is 60% to 65% is to hold the material tightly with your hands. If watermarks are seen but no water drips, and it can be scattered when it falls to the ground (65% moisture content is not too wet, please pay attention to correct judgment).

3. The pile is overturned.

After the water content is adjusted, the pile should be built. The height and volume of the pile should not be too short or too small. The requirements are: the pile height is 1.5 to 2 meters, the width is 2 meters, and the length can be freely adjusted according to the amount of fermented materials, but it should not be less than 2 meters. Lebeifeng fertilizer fermentation agent is aerobic fermentation, so the oxygen supply measures should be increased, and it is advisable to mix well, turn frequently, and ventilate. Otherwise, it will cause anaerobic fermentation and produce odor, affecting the effect.

4. Complete fermentation.

Generally, when the temperature reaches above 65℃ in the first 1-2 days of fermentation, it is necessary to turn it over and then continue fermentation. When the temperature reaches 65℃ again, it needs to be turned over for the second time. Generally, fermentation can be completed within a week. The material becomes dark brown and the temperature begins to drop to room temperature, indicating that fermentation is complete.

5. Adjust pH

After fermentation is completed, test the pH value (the pH of the fermented material using Lebefeng fermentation agent will naturally drop to 6.5-7.5, and generally no adjustment is required). Earthworm feed generally requires a suitable pH value of 6-7.5, so the pH value of earthworm feed should be properly adjusted to make it close to neutral to suit the growth of earthworms.

The starting temperature of the fermented materials using Lebefeng fermentation agent is preferably above 15°C (it can be operated in all seasons and is not affected by the season. It can be fermented indoors or in a greenhouse when the temperature is very low in winter), and the fermentation temperature should be controlled below 70-75°C. The materials fermented with Lebefeng fertilizer fermentation agent have good palatability and rich nutrition. They can not only be used to raise earthworms, but also to feed fish, shrimp, mealworms and other lower animals. Of course, if users want to ferment feed to raise higher animals such as pigs, chickens, ducks, and geese, they can use Lebefeng feed fermentation agent to ferment chicken manure and rice bran, wheat bran and other crop waste materials with relatively high nutritional content, which can greatly reduce breeding costs and increase the economic benefits of breeders.
