Worms are a very suitable food for ornamental birds, ornamental fish or chicken farms. However, the amount of earthworms in nature is not enough to meet the current livestock needs of farmers. The model of raising earthworms is also becoming more and more popular. However, if you want high yield, there are problems related to worm farming techniques you must definitely understand.
About the breeder
– Understand some basic physiological and ecological characteristics of worms.
– Have minimal knowledge about the technological process of raising worms.
– Properly practice the technical requirements and technological process of worm farming.
About the barn
Livestock cages must be placed in a cool place, not flooded and should not be exposed to direct sunlight, with regular, neutral and clean irrigation water; need heat, good drainage. Ensure the conditions of temperature and humidity. Measures should be taken to prevent natural enemies (ants, toads, frogs, etc.) Holes or tanks for raising worms must have a roof to avoid rain and sun. At night, there should be bright lights, especially in rainy and windy times to avoid the worms crawling elsewhere.
The most suitable temperature for worms to develop is from 20oC – 30oC. For people in some northern areas, it is important to pay attention: In winter the temperature is low, at this time we need to cover carefully, light electric lights at night so that the temperature is always kept at an appropriate level, avoiding where worms hibernate or freeze to death.
Must regularly water the worms (in summer and dry season at least 2 times / day). The appropriate humidity can be identified by: Grabbing the biomass in the barn by hand, then releasing it; if you see the biomass remains the same and our hands are only wet, it is enough, but if we see the water running out or the biomass is broken and falling, it is too wet or too dry. Attention should be paid to watering and moisturizing right from the time of stocking because the worms are shocked when moving. Daily check humidity and additional watering, it is best to water several times a day when it is hot, the amount of water for each watering is small. Irrigation water should have a neutral pH, not contaminated with salt or alum. If a substrate with a porous and large grain texture is used, the humidity can be maintained at a high level and vice versa.
About the light
Worms are very afraid of sunlight, so we need to cover the cage carefully during the day to avoid ultraviolet rays from entering the cage. It is best to have a cover on the surface of the bed. However, it is necessary to keep the barn cool.
About the substrate
It is an important factor for worms in the early life, a shelter when the worms come into contact with a new environment and must meet the following factors: porous, clean, rich in nutrients… The substrate has a porous structure, texture and texture. Relatively coarse structure, good moisture retention capacity, no heat reaction, pH is not outside the tolerance spectrum of worms, can be temporary habitat for worms when facing adverse conditions.
About the air
Co2, H2S, SO3, NH4 gases are enemies of worms, so the worm’s food must be clean and free of harmful chemical components.
Worms consume an amount of food equivalent to their body weight each day, so we have to make sure that there is enough food to feed the worms. Worm food includes: Manure of cows, buffaloes, goats, pigs, chickens, ducks, rice straw, organic waste. In which fresh cow dung and fresh buffalo manure are the most favorite dishes of worms; remaining chicken manure, pig manure, duck manure, need to be composted before feeding. Food is organic waste, so it should be in a decomposing form, and should not have too high a salt and ammonia content; The species is relatively diverse, but the most suitable are materials with a C / N ratio of about 10: 1 such as cattle manure, which are more attractive to worms than dry or composted fertilizers.
Can process worm food including straw, bagasse, sawdust… 50%; green leaves, vegetables of all kinds, banana peels… 20% and cattle and poultry manure 30%. Among them, cow dung is the best. For every 2 kg of seedworms (about 5000 worms) consume 1-2 kg of compost per day, every 1000 worms every month eat 100 kg of compost. Mix all kinds of raw materials at the ratio of 70% water, 30% garbage … (store the raw materials of straw …) to compost as compost pile outside, plastered with tight mud, high temperature, for up to 3-4 weeks. . When the temperature drops to ambient temperature, feed the worms.
How to feed
– Prepare food: people put manure in the bin or compost pit at least 1 day in advance, then put the water in to soak in a thick paste (recommended as long as possible).
– Feed the people with composted cow dung for the worms to eat, when feeding, pay attention not to spread the food evenly across the bed, but solve each small box from 3 to 5 cm so that the worms can crawl to eat and have a place for the worms. breathe. After feeding, people cover it like before feeding so that the worms crawl up the bed to eat because the worms are afraid of light.
How to take care
– After 1 to 2 days, people regularly check, if the food is spongy, that means the worms have eaten all, continue to feed as the first time on a regular basis, do not let the worms get too hungry, they will die or give up. Go.
– Note: People regularly check the humidity, do not let the worm bed too wet, too dry, check the worm manure at the bottom of the barn for rotten and sour phenomenon. If so, collect all the old manure and raise it as normal.
– Measures must be taken to prevent natural enemies of worms that are toads, crickets, chickens, mice, …… to avoid these natural enemies attacking the worm beds, which will cause damage to livestock farmers.
– After 30 days, you can double the area of the worm bed by removing the old bed to the next area and then feeding the worms like the initial release and taking care as mentioned above.
– If feeding animals, remove the top layer of eggs and worm cocoons, remove the next layer about 8cm into a pot or brick floor, wait for about 7 to 10 minutes for the worms to crawl to the bottom, then people remove the sediment until when the required amount of worms is used.
– After 2-3 months, it is necessary to collect worm droppings by removing the top and middle layers about 15cm, removing all the worm droppings to another area, this number of worms has a lot of eggs and worm cocoons, so solution 1 thin layer of cow dung on the surface to lure worms 3-4 days, collect once in a period of 21 days, the remaining amount of worm droppings, if you see worms, you will remove them to the brick floor or make a small pile of tarpaulin (outdoors can be removed). a lot of light, but don’t put it in a sunny place, lest the worms die) wait about 7-10 minutes for the worms to get down to the end of the bed to collect worms and worm droppings.
