Feeding chickens efficiently chickens

Musca domestica breeding larvae called fly maggots, it is a high quality animal protein feed. The nutrient composition of fly maggot is similar to that of high-quality fishmeal. The crude protein content of dry product is 59%-65%, crude fat is 11%-13%, calcium is 0.3%-0.7%, and phosphorus is 1.7%-2.6%. Feeding layer hens with 10% fly maggots resulted in a 20% increase in egg production compared to those fed the same amount of fishmeal and a feed reward increase of 15% or more. The breeding of fly larvae is divided into two stages: the breeding of fly breeding and the breeding of fly maggots. Flies are raised to obtain a large number of fly eggs for the purpose of breeding fly maggots. The eggs produced by fly-feeding chickens are rich in vitamins and carotenoids. The eggs in the eggs contain no more than 3% of the eggs, and the protein content is more than 12%. They contain many amino acids, sodium, potassium, which are necessary for the human body. Calcium and other minerals.

First, breeding flies

1. Make fly cages. Seed fly has fly power and must be kept in cages. A rectangular frame of 65 cm, 80 cm, and 90 cm was made from wooden bars or 6.5 mm steel bars. A plastic window screen or an eye-catching copper wire mesh was placed outside the rack and gauze gloves were placed on the side of the cage net for feeding and handling. Each fly cage is equipped with a feed bowl and a drinker. A cage can raise 40 000-50 000 adults.

2. Prepare feed. Seed flies were fed with 5% syrup and milk powder; or fresh taro were ground, 95 g mash, 5 g beer yeast were added, 155 ml cold water was added, and mixed and fed. When roosting, you can use stinky eggs and feed them in a white porcelain jar. Feed and water are changed once a day.

3. Breed flies. From the source of the fly, the fly maggots can be washed into the fly cages and fed and watered when it reaches 5%. Three days after the flies began mating, they were placed in spawning trays. The dish is filled with 2/3 height of attractant. The attracting material is prepared by adding wheat bran, chicken feed or pig feed, and adding an appropriate amount of diluted ammonia water or ammonium carbonate water. Pick eggs 1-2 times a day and pour the eggs together with attractants into the larval culture room.

4. Control temperature and humidity. The flyhouse temperature should be controlled at 24°C-30°C, and the relative air humidity should be controlled at 50%-70%.

Second, feed fly lice

1. Feeding equipment. A small amount of rearing can use cylinders, pots, etc., and large-scale rearing is recommended. A 1.20.80.4-meter pool was built on the ground with bricks and the walls were cemented. The pool mouth is covered with a wooden frame covered with fine-eye copper wire or a sieve.

2. fly maggot culture. Cultivation materials can be used livestock and poultry manure, can also be used distiller's grains, sugar tanks, bean curd residue, slaughterhouse leftovers and other preparation. Culture material moisture content 65%-70%, PH value 6.5-7. Each square meter of culture pond is poured into 35-40 kg of culture material, and the thickness is 4-5 cm. Each inhabited fly egg is inoculated with 200,000-25 million grains and weighs 20-25 grams. When inoculated, fly eggs can be evenly spread on the surface of the material. Keeping the culture room dark, the temperature of the culture material is controlled at 25°C-35°C. After a few days of culture, the temperature of the culture material is decreased and the volume is reduced. At this point, fresh material should be supplemented according to the amount and growth of fly maggots. At a temperature of 24°C to 30°C, after 4-5 diurnal nights, individual fly weights can reach 20-25 mg. The fly larvae tend to be mature, and Chen stays as a seed for larvae. The remaining fly larvae can be harvested and harvested according to the following methods.

3. Separate recovery. 1 chicken food separation. Spoon the mash and the rest of the culture into the chicken circle and allow the chicken to eat fresh oysters before removing the broth. 2 strong light irradiation separation. Because fly maggots are afraid of strong light characteristics, they can be irradiated with strong light. After they are moved downwards from the surface of the culture material, layers of surface culture material are stripped, and a large amount of fly larvae can be obtained at the bottom layer. 3 water separation method. The mash and the remaining culture material are poured into the water tank all together, stirred until they float above the water, and are removed with a sieve.

4. Scientific feeding. The fly larvae are used as feedstuffs, and most of the poultry are fed directly with fresh quail (the dry ploughs are mostly used to feed the livestock, and the dried milled grains are soon to be smashed and fed into the compound feed).
