Insect mites are a highly nutritious and protein-rich source of animal feed, offering an excellent alternative to traditional feed sources. Studies have shown that insects can contain up to 62% protein, making them a valuable resource for poultry farming. One effective way to utilize this is through artificial breeding methods, which allow farmers to produce feed on-site, reducing costs and improving sustainability. These methods are simple, efficient, and can be implemented with locally available materials. Below are ten different techniques for raising insect larvae to feed chickens.
1. **Chicken Manure Breeding Method**
Dry chicken manure and mix it with small amounts of rice bran and wheat bran. Combine the mixture with thin mud and cover it with straw or weeds. Form a concave shape at the top and pour sewage in once or twice daily. Within about two weeks, a large number of small bugs will appear, which can then be used to feed the chickens. After the worms are consumed, the pile can be reused for further breeding.
2. **Fermented Chicken Manure with Brewers' Grains**
Mix fermented chicken manure with brewers’ grains or soy sauce residue in a 4:1 ratio. Spread evenly on the floor, keeping the layer no more than 17 cm thick and maintaining a moisture level of around 70%. Add some rotten vegetables or fish on top to attract flies, which will lay eggs. Within a few days, a significant number of insects will develop, ready for the chickens to eat.
3. **Cow Dung Breeding Method**
Dry and crush cow dung, then mix with a small amount of rice bran and bran. Combine with thin mud and form a round heap measuring 100–170 cm in diameter and 100 cm in height. Cover with straw and water it 2–3 times daily, keeping the inside semi-dry and semi-wet. After about 15 days, many insects will emerge, and the chickens can be let to feed on them.
4. **Straw Breeding Method**
Cut rice straw into 3–7 cm pieces, boil them for 1–2 hours, and bury them in a pit measuring 100 cm long, 67 cm wide, and 33 cm deep. Cover with 6–7 cm of mud and seal it. Keep the pit moist by watering daily. In 8–10 days, a large number of insects will appear, ready for the chickens to eat. After consumption, cover the pit again to continue the breeding cycle.
5. **Fresh Grass and Leaf Breeding Method**
Mix 80% fresh grass or leaves with 20% rice bran, add a small amount of cooked water, and place the mixture in a container or pool. After 5–7 days, a large number of insects will develop, which can then be fed to the chickens.
6. **Pine Needle Breeding Method**
Dig a deep pit, 70–100 cm in depth, and fill it with 30–50 cm of pine needles. Pour in a moderate amount of rice washing water, then cover with 30 cm of soil. After 7 days, a large number of insects will appear, which can be harvested and fed to the chickens. After consumption, refill the pit with pine needles to continue breeding.
7. **Bean Cake Breeding Method**
Mix a small amount of bean cake with fermented bean curd residue and other ingredients such as cereals and leaves. Place the mixture into a pit 7–10 cm deep, cover with a thin layer of clay, and then add straw on top. After 6–7 days, many insects will be produced and can be driven to feed the chickens.
8. **Bean Curd Residue Breeding**
Place 1–1.5 kg of bean curd residue into a water tank, add one barrel of rice washing water, and let it sit for 1–2 days. Then cover the tank and wait 5–7 days for the larvae to develop. Remove the insects, wash them, and feed them to the chickens. After they are eaten, add more residue to continue the process.
9. **Soybean and Peanut Cake Breeding**
Mix 0.6 kg of soybeans, 0.5 kg of peanut cake, and 1–1.5 kg of pig blood. Seal the mixture in a container and keep it at around 25°C for 4–5 days. Moths will begin to appear, followed by an increasing number of larvae. This method can feed approximately 50 broilers, providing high-quality protein and nutrients similar to fish meal.
10. **Distiller’s Grain and Bran Breeding**
Choose a wet area, dig a pit about 30 cm deep, and line the bottom with straw. Add 5–6 cm of chopped straw, corn stalks, and weeds mixed with bran and distiller’s grain. Add water and place the mixture in the pit, then cover with soil. At temperatures above 30°C, larvae will appear within 15 days.
Throughout all these methods, it's important to maintain the larvae in a semi-dry condition—neither too dry nor too wet—to ensure optimal growth and development. These techniques not only provide a sustainable feed source but also help reduce waste and promote eco-friendly farming practices.
