Can feeding laying hens with fly maggots improve egg quality?

At present, insect chicken and ecological eggs have become a good project for farmers to get rich and increase their income, and have also become a hot topic of concern for many farmers, laid-off workers, and those seeking wealth. According to the breeding experience of Jin Renren, general manager of Zhengzhou Jinrong Ecological Breeding Demonstration Park and the first person in my country to breed insect chicken, it is believed that the breeding of insect chicken and ecological eggs should focus on the following aspects:

1. Breeds: local laying hens, British noblewoman chickens, French guinea fowls, American colorful chickens, mountain black-skinned chickens, etc.

2. Breeding method: free range.

3. Environment selection:

Generally, farmers with conditions can plant trees and shrubs to adjust the local microclimate. To create a good living environment for cultivating insect chickens and laying ecological eggs, economic forests can generally be selected because the range is relatively wide and there are many varieties of trees, including broad-leaved forests, coniferous forests, trees, shrubs; young and mature; evergreen and deciduous. Economic forests play a decisive role in the formation of local microclimates. Therefore, the breeding place of insect chickens should be arranged according to the climate changes in different seasons. In summer, it is advisable to arrange them in tree forests, broad-leaved forests, evergreen forests, and mature tree gardens, such as chestnuts, bamboo, oil tea forests, citrus, cypress, pear orchards, jujube orchards, plum gardens, vineyards, etc.; in winter, it is better to arrange them in deciduous and young orchards, such as chestnuts, peach orchards, plum gardens, pear orchards, bamboo forests, and various orchards and economic forests that have just been planted for 1-3 years. Here, the main thing is to use the relationship between trees and sunlight to create a more suitable production environment for insect chickens to increase the egg production rate of insect chickens.

4. Feeding method: maggots + raw grain (ratio 5-15%)

Insect chickens and ecological eggs are cultivated without full-price compound feeds, but with raw grains or cereals. The crude protein content of raw grains or cereals is seriously low, so they need to be supplemented with foods with high protein content. Analysis by the Henan Academy of Agricultural Sciences shows that the amino acid content in fly maggot protein powder is moderate, the composition is reasonable, and it has the characteristics of strong palatability, balanced nutrition and rich immune substances. At present, no animal protein can compare with it, and it is the most important feed in the cultivation process of insect chickens. The insect chickens fed by this method are not only delicious, but also have natural fragrance. The yolk color is more than 11 (the yolk color of ordinary eggs is only 5-6). The vitamin E content is three times that of ordinary chickens. It is very popular among consumers in my country's poultry egg market. The "Insect Chicken Brand" insect eggs developed and produced by Zhengzhou Jinrong Biotechnology Co., Ltd. are 56 yuan/box (38 pieces/box), but they are still in short supply. Why are insect eggs so popular? It turns out that fly maggots are a high-quality protein source with a significantly higher protein content than fish and meat, and the various amino acids contained are most in line with the needs of the human body. Fly maggots are rich in a variety of trace elements necessary for life. The eggs laid by free-range laying hens fed with fly maggots are not only of good quality and taste, but also contain no antibiotics and hormones, and will not cause food safety problems, meeting the public's requirements for food hygiene, safety, and greenness.

5. Replenish green materials in time

In addition to rotational grazing in small areas, insect chickens should also plant green feed outside the breeding farm and supplement it during the later period of feeding in the grazing area. If there is no rotational grazing and no regular supplementation of green feed, it is bound to cause nutritional deficiencies in laying hens, especially vitamin deficiencies, which will affect egg production. It should be emphasized here that: first, rotational grazing is required, and second, green feed should be fed in the later period of rotational grazing. Third, green feed should be fed every day in places where there are no conditions for rotational grazing. It is best to chop and mix the green feed for feeding. When raising insect chickens in economic forests, if there is no green on the ground, more than 50 grams of green vegetables, tender grass or artificial pasture can be fed every day.

6. Notes:

(1) Beware of sexual harassment of chickens. Many chicken farmers are used to raising male and female chickens together, which is not good for the growth and production of hens. They should be raised in separate groups. When male and female chickens are raised together after they reach sexual maturity, the hens will be sexually disturbed by the roosters, which will affect the increase in egg production. Therefore, when raising insect chickens, native broilers should not be raised together. It is best to separate the chickens in the chick stage. If this is not possible, male and female chickens must be raised in separate groups after they start laying eggs. Of course, it is beneficial to put 2-3 roosters for every 100 hens. A certain amount of sexual stimulation is conducive to improving the level of egg production.

(2) Wake up brooding hens in time. If laying hens stop brooding, their egg production will be seriously affected. Therefore, effective measures should be taken according to local conditions to shorten the brooding period of laying hens. There are many folk methods to wake up brooding hens, but the main contents are nothing more than the following: First, use physical methods to make them restless and do everything possible to make them move, such as tying rattles or bells on their feet; second, use pharmacological methods, such as feeding 1 tablet of 25 mg of ephedrine hydrochloride per day, which will take effect in 3 days, with low cost and good effect; third, use a small amount of estrogen to supplement, regulate and maintain the level of estrogen in the body, so that the brooding period is shortened and production can be resumed as soon as possible.

What is the best feed ratio for feeding maggots to chickens?

Generally, there is no strict ratio. It depends on what other feeds you use. Generally, if you raise chickens in the woods, there are already insects and grass. You can sprinkle some rice and wheat, and then add one or two dried maggots or three or two fresh maggots to three catties of chicken feed. It is better to feed in the morning. In fact, it is impossible to breed maggots in large quantities. The reproduction rate of 2 is a theoretical value. In addition, the cost of maggots is relatively high, and one catty costs two or three yuan on average, which is more expensive than protein feeds such as fish meal.

1. Breeding of flies

1. Make fly cages. The flies have the ability to fly, so they must be raised in cages. Use wooden strips or 6.5mm diameter steel bars to make a 65cm×80cm×90cm rectangular frame, cover the frame with plastic window screens or fine-mesh copper wire mesh, and install gauze gloves on one side of the cage net for feeding and operation. Each fly cage is equipped with a feed bowl and a waterer. One cage can raise 40,000 to 50,000 flies.

2. Prepare feed. Feed the flies with 5% syrup and milk powder; or grind the fresh maggots, take 95 grams of maggot slurry, 5 grams of brewer's yeast, add 155 ml of cold boiled water, mix well and feed. When first raising, you can use rotten eggs and put them in a small white porcelain jar for feeding. Change the feed and water once a day.

3. Breeding flies. The source of breeding flies can be obtained by washing the fly pupae and placing them in the breeding fly cage. When the pupae have emerged to 5%, start feeding and watering them. Three days after the breeding flies begin to mate, place them in the egg-laying tray. Fill the tray with 2/3 of the attractant. The attractant is made of wheat bran, chicken feed or pig feed, with an appropriate amount of dilute ammonia or ammonium carbonate water. Collect eggs 1 to 2 times a day, and pour the eggs and the attractant into the larval culture room for cultivation.

4. Control temperature and humidity. The temperature of the fly breeding room should be controlled at 24℃~30℃, and the relative humidity of the air should be controlled at 50%~70%.

2. Raising maggots

1. Breeding equipment. For small-scale breeding, tanks and basins can be used, while for large-scale breeding, ponds are suitable. Use bricks to build a 1.2×0.8×0.4m pond on the ground, and use cement to plaster the pond wall. Use a wooden frame to cover the pond mouth with fine-meshed copper wire or silk sieve.

2. Fly maggot cultivation. The culture medium can be made of livestock and poultry manure, or wine lees, sugar troughs, tofu dregs, slaughterhouse scraps, etc. The water content of the culture medium is 65%~70%, and the pH value is 6.5~7. Pour 35~40 kg of culture medium into each square meter of the breeding pond, with a thickness of 4~5 cm, and inoculate 200,000~250,000 fly eggs per square meter, weighing 20~25 grams. When inoculating, the fly eggs can be evenly sprinkled on the surface of the material. Keep the culture room dark, and control the temperature of the culture medium at 25℃~35℃. After a few days of cultivation, the temperature of the culture medium drops and the volume shrinks. At this time, fresh material should be added according to the number and growth of fly maggots. At a temperature of 24℃~30℃, after 4~5 days and nights, the weight of individual fly maggots can reach 20~25 mg. The fly maggots tend to be mature, and the remaining fly maggots can be separated and harvested according to the following methods, except for those that are kept for seed to pupate.

3. Separation and harvesting. ① Separation with chicken feed. Sprinkle maggots and remaining culture medium into the chicken pen, let the chickens eat fresh maggots, and then remove the culture medium. ② Separation by strong light irradiation. Since fly maggots are afraid of strong light, strong light irradiation can be used. After they move downward from the surface of the culture medium, peel off the surface culture medium layer by layer, and a large number of fly maggots can be obtained from the bottom layer. ③ Water separation method. Pour the maggots and the remaining culture medium into a water tank, stir until the maggots float on the water, and then scoop them out with a sieve.

4. Scientific feeding. When fly maggots are used as feed, fresh maggots are mostly used to feed poultry directly (dry powder is mostly used to feed livestock, that is, the maggots are scalded to death, dried, ground into powder, and added to compound feed for feeding).

This does not require any formula. If you breed a lot of maggots, you can feed more maggots! This can reduce feed costs. Free-range chickens can eat by themselves. Feeding them with corn and maggots will make them stronger. If the eggs produced by chickens fed with maggots and corn can be applied for green food, the price of your eggs will be high! The price of chickens sold will also be higher than others.

Chickens fed with maggots are called worm chickens, and they can lay worm eggs!

Insect eggs are produced by using ecological chain breeding technology, using natural grain insects, and raising insect chickens. The eggs are rich in vitamins and carotenoids. The fat content of insect eggs is generally no more than 3%, and the protein content exceeds 12%. It contains a variety of essential amino acids, sodium, potassium, calcium and other minerals and vitamins B, E, etc.

Insect eggs are nutritional functional eggs successfully developed by many experts of China Fly Network, using fly maggot biotechnology, high-tech microbial technology, bio-enrichment technology and bio-nutrition fortification technology, after years of practice and research. This product contains EPA (the abbreviation of eicosapentaenoic acid, commonly known as the vascular scavenger), trace elements such as iodine, selenium, iron, zinc, and various vitamins, amino acids and other life substances that are beneficial to human health, and is effectively preserved in a life state. It has the characteristics of high lecithin, low cholesterol, no drug residue, safe and non-toxic side effects. It is a special egg that can develop intelligence, improve IQ, prevent and treat cardiovascular and cerebrovascular diseases, diabetes, Alzheimer's disease, brain atrophy and other diseases. It is especially suitable for pregnant women, infants, teenagers, middle-aged and elderly people.

No need to mix, just feed directly
