The technique of raising chickens with fly maggots

Why the recent breeding of maggots is more popular, what can maggots do? In fact, the use value of fly maggots is particularly large, because the nutritional value of fly maggots is particularly high, especially rich in protein, it is a very good way to raise some chickens, ducks, geese and other animals.

The technique of raising chickens with fly maggots

The protein content of fly maggot powder is as high as 60%, and the amino acid balance is the best feed protein source, which is equivalent to fish meal. The maggot protein bred by a cage of flies can raise 5,000 pheasants in the summer season when the temperature is suitable. The chicken feed mixed with 11.3% maggot powder can save 40% of the feed and reduce the cost by more than half. The new technology of raising chickens with fly maggots has the following main points:

1. The chickens were fed with fly maggots, 4 grams per chicken at the age of 0-6 weeks, 8 grams at the age of 7-12 weeks, and 10 grams at the age of 13 weeks. The crude protein content in the basal diet of 0-6-week-old chickens was 19%. The crude protein content of 7-12-week-old chickens was 15%. The crude protein content of 13-week-old chickens was 16%.

2. Using fresh maggots to feed chickens in the growth stage, each kilogram of fresh maggots can increase the weight of chickens by 0.75kg, advance the date of laying, and increase the total egg production and average egg weight.

3. The laying hens were fed with 10% maggot and 10% fish meal respectively, and the basic diet was the same. The laying rate of the chicken fed with fly maggots was 20.3% higher than that of the chicken fed with fish meal, the feed reward increased by 15.8%, and the feed cost decreased by 31.2%. Fresh maggots are sprinkled directly into the trough or on the ground and fed twice a day.

What are the advantages of raising chicken with fly maggots

1. Supplement protein

Animal feed is mainly composed of protein feed (such as fish meal, bean cake, silkworm pupa, etc.) and energy feed (such as corn, wheat, sorghum, etc.). Because of the lack of protein feed, local chickens are generally fed with energy feed such as corn and wheat, resulting in a serious lack of protein feed, the feed conversion rate of the raised chicken is very low, and the feed cost is too high. Artificially cultured flies, maggots and other insects are ideal cheap protein feed, and their protein content is very close to that of fish meal. As a cheap animal protein feed for raising native chickens, fly maggots can greatly reduce the feed cost and produce high quality pollution-free products.

2. Increase production capacity

The vocational education group of Xiangshui Middle School in Wanzhou, Chongqing reported that feeding chicks with fresh fly maggots significantly accelerated the growth and development of laying hens, which could lead to the production of laying hens one month earlier, and the egg production increased by 0 per kilogram of fresh maggots. 75kg, which can increase the laying rate by 10% Mur20%, which is 1-1 more eggs per chicken per year than the control group fed with fish meal. Five kilos. When the broilers were fed with fresh maggots, the weight gain rate was 70% higher than that of the control group (fed with the same amount of fish meal), and the feed reward was increased. The laying rate was 16% and 18% higher than that of the control group fed with the same amount of fish meal when 8% Mel 10% maggot meal was added to the laying hen diet.

3. Enhance the disease resistance of chickens.

According to relevant scientific tests, fly maggots are rich in antimicrobial peptides, which can significantly improve the immunity of animals and achieve the effect of less disease or even no disease. The use of maggots and other maggots in chickens can increase the anti-risk ability of the farm and save a lot of unnecessary drug expenses.

Breeding and breeding of seed flies

Breeding flies should be kept in the fly room. The size of the fly room can be built as needed, or it can be modified with old houses. Doors and windows are equipped with glass and screen windows to facilitate temperature regulation, and fans are installed on the walls to regulate the air. There should be heating equipment in the room to keep the winter temperature at 20: 23 ℃ and the relative humidity at 60% to 70%. Black cloth curtains are installed on the passageway to prevent flies from escaping. There are feeding racks in the room, which are divided into upper, middle and lower floors. The feeding rack is made of iron or wood. Fly cages made of nylon gauze net are placed on each shelf. The cages are 100cm long and 80cm high. Seed flies are kept in cages. 12000 flies are raised in each cage. Cloth sleeves are added to each cage for feeding, water and egg collection. 12000 adult flies are fed 20 grams of milk powder every day, and the feed is placed in a basin with gauze cushion to let adult flies stand on the gauze and suck.

Feed and water are changed once a day. Put gauze in the water basin and wet wheat skin in the spawning cage for the flies to lay eggs. The eggs are collected once a day in the fly cage and sent to the maggot room to breed maggots. The number of eggs laid by the species fly is the most from 8 am to 3 pm every day, and the time for egg collection should be appropriate. Each batch of flies will be eliminated after 15 or 20 days, kill them with hot water or steam, dry and grind them for livestock and poultry feed, and then replace them with another batch. In the production of maggots, maggots pupate as a new fly species, there are two ways. One is to pupate naturally and wash the fly pupae with water, and the other is to take out the maggots to promote pupation when the maggots turn yellow for about 5 to 6 days.

Matters needing attention in raising chickens with fly maggots

1. The total amount should be 20% of the feed and no more than 30% high. If you eat too much, the chicken eats maggots and pulls maggots and then eats them back. The most terrible thing is that it may lead to excess chicken protein, stagnant water in the belly and sudden death.

2. Immature fly maggots should not be fed to chickens. It's not what people often say, "Little maggots feed chicks, big maggots feed big chickens." Because the little maggot has undigested bacteria in his belly, and his body is also stained with bacteria. Mature maggots no longer eat, and there is no black silk in the stomach. Crawling out of the mature maggots, the dirt on the body has also been wiped clean.

3. Empty-stomach chickens should first eat some other feed, and then feed maggots, which has a high utilization rate.

The editor talked about some of the benefits of raising chicken with maggots. I think we all know the role of maggots. In fact, native chickens and eggs, which have been selling very well, mainly eat fly maggots. Chickens that eat fly maggots are nutritious and taste more delicious.
