Application of fly maggot as the feedstuff for cultivated shrimp and turtle

Abstract

The present invention provides a fly maggot application as the feed of prawn and turtle culture; the fly maggot is taken as the only feed for prawn and turtle culture. The fly maggots comprise live one, dried one, frozen one and fly maggot powder. Other feeds or additive which accounts for 10 percent of the sum can be added besides fly maggot; the growing time of prawn and turtle can be shortened by 20 to 30 days with the fly maggot as the feed compared with the growing time when people only throw feed for feeding prawn and turtle. At the same time, the disease incidence is reduced and survival rate is increased; no pollution is caused and the environmental performance is good. Prawn and turtle like the thrown fly maggots and the feeding time is fast without residue and water pollution; in addition, the disease resistance of prawn is strong. The immunity and activity are both greatly promoted which promotes the growing. The fly maggot contains a plurality of high-activity digestive enzymes and can produce a plurality of vitamins and unknown growing factors which can help shrimp digest and absorb. In this way, the cleanness and eco-environment at the bottom of the pond can be kept relatively stable and the finished products of prawn are all green food.

Description

technical field [0001] The invention relates to an animal feed, in particular to a feed for cultivating shrimps and turtles with fly maggots. Background technique [0002] At present, farmers use artificially synthesized mixed feed for breeding shrimp and turtles, which is characterized by granular form. The feed must be digested in a short time after it is put into the pond, otherwise the feed will be destroyed when it encounters water. After swelling and rot, mold will seriously affect the water quality and bring diseases and dangers to the raised prawns and turtles. At the same time, various additives are needed to prevent various diseases. [0003] At present, some people use fly maggots as feed additives for prawns. They use fly maggots to make maggot slurry and add them to the feed of prawns at a temperature not exceeding 41°C. The amount of maggot slurry added is 10-20% of the weight of the feed. , and at the same time add the following components: V A 2000~2200 int...
