The effect of fly maggot as feed

The crude protein content of fly maggot powder is as high as 56% 63% (average 59.5%), fat 13%, ash 7%, sugar 3.1%. As a high-protein feed, the nutritional level of fly maggots is comparable to that of imported Peruvian fish meal, 1.3 times that of bean cake and 1.9 times that of bone and meat meal. It contains 15% crude protein and 5.8% crude fat, which can not only directly feed conventional pigs, chickens, ducks and fish, but also the best live bait for special animals, such as shrimp, crab, eel, rice field eel, American frog, bullfrog, seven-star fish, grouper, turtle and so on. Fly maggots are easy to cultivate, low cost and short cycle. 2000 grams of dung can produce 500g maggots. A cubic meter fly cage can produce about 150 grams a day. If you use 10 fly cages with upper, middle and lower layers, you can get 20-25 kg of fresh maggots every day. The total cost of producing 1000 grams of fresh maggots is only 0.14 yuan. Based on 4 kg of fresh maggots equivalent to 1000 grams of fishmeal, it is only 30% of the price of fishmeal. According to the experiment of Beijing Feed Research Institute, the average daily production of fly maggots is 9.75 kg on an area of 18 square meters. In the experiment of feeding chickens with self-propagated maggot feed, 10% fly maggots were added to the feed and 10% fish meal was added to the control group. the results showed that the laying rate of the former was 20.3% higher than that of the latter, and the feed reward was increased by 15.8%. Feeding piglets with 100 grams of fly maggots increased weight by 7% and reduced cost by 13.2% compared with feeding the same amount of Peruvian fish meal. After the large-scale production of fly maggots in the farm of Guangxi Labor Reform Administration, the average daily output of fresh maggots is 300 kg. The body weight of each fish increased from 65 grams to 175 grams after 10 days, and the weight gain rate was 41% higher than that of the control group fed with conventional diet. The pig formula feed was prepared with maggot meal instead of the same amount of fish meal. In the experimental group, the weight gain of pigs increased by 5.1%, and the protein content of pig lean meat increased by 5%. When the chicken feed was prepared with maggot meal instead of fish meal (the same amount), the survival rate was increased by 9%, the weight gain was increased by 20%, the feed cost was reduced by 7%, and the feed was saved by 20%. 40%. A farmer in Fenglin Village, Batou Township, Xingguo County, Jiangxi Province, used bamboo strips to weave fly cages and raised flies to 14 cages, producing 30 kilograms of fly maggots per day, enough feed for 1000 soft-shelled turtles. Since putting flies into the ecological chain, his investment in raising soft-shelled turtles has been reduced by nearly half, while the annual output value has doubled. -- good stuff, thank you.-- good stuff, but I haven't heard of anyone using it.
