Fly maggot breeding method

Abstract

The invention relates to a fly maggot breeding method, belonging to the technical field of fly maggot breeding; the method utilizes the property of rich protein contained in fresh shrimp shell and provides the mixture of the fresh shrimp shell and adequate wheat bran for breeding flies to lay eggs; 60% of the fresh shrimp shell is protein which can be digested little by common animals, but the flymaggot can easily absorb the protein of the fresh shrimp shell, so the fresh shrimp shell is crushed by a grinder as feed of fly maggot breeding; the fly maggot absorbs the protein and transforms theprotein into animal protein which can be easily digested and absorbed, so the fresh shrimp shell is a better raw material compared with common fly maggot breeding and the fly maggot breeding method can increase the output by over 30%; in general, four tons of fly maggot breeding on pure wheat bran are dried into one ton of finished product while only 3.5-3.7 tons of fly maggot breeding on the mixture of fresh shrimp shell need to be dried into one ton finished product due to high protein quality.

Description

technical field [0001] The invention relates to a method for culturing fly maggots and belongs to the technical field of fly maggot cultivation. Background technique [0002] The use of wheat bran to raise fly maggots is a material that was used decades ago and is still used by most fly maggot farmers today. There are also many places that use materials such as animal excrement to breed fly maggots, a large amount of odor in the breeding environment to breed fly maggots, and the like. Referring to the past and present technologies of wheat bran farming, there is almost no progress, and there are mainly the following problems: [0003] 1. Low output and high cost. In the high temperature season, about 2.5-3 kg of wheat bran can produce 1 kg of fly maggots. When the temperature is slightly lower, the yield is lower, and it takes about 4 kg or more to produce 1 kg of fly maggots. Calculated, the cost of producing 1 kg of fly maggots is 6 to 10 yuan. [0004] 2. Wheat bran d...

[0004] 2. Wheat bran deteriorates quickly

In high temperature (daily average temperature above 28°) season, due to the strong appetite of fly maggots, the wheat bran will be eaten by fly maggots before it turns sour, and the effect will not be significant, but at a slightly lower temperature (room temperature is lower than 25°), wheat bran will be found The same goes rancid, but the fly maggots don't like to eat it, resulting in a decrease in production, and the number of eggs laid by the breeding flies is small and the death is fast.
