Problems solved by technology

However, the addition of exogenous microorganisms, in addition to increasing the cumbersomeness of the preparation process, also requires high control of the amount of addition. Too many microorganisms will have adverse effects on fed animals and even cause diseases.
In addition, the raw material composition of the medium in Dr. Qiao Yonggang's research includes soybean meal, rice bran, enzymatic feather meal, cotton meal, bran, brown sugar, milk powder and starch, etc. The raw material composition is relatively complicated and due to the addition of feather meal, brown sugar, milk powder, etc The cost of raw materials is too high to be suitable for commercial production

Embodiment 1

[0040] A kind of fly maggot protein feed, its preparation method comprises the steps:

[0041] Housefly (Muscadomestica) seed flies were cultured in sarongs at a density of 0.5 cm 3 / Only. Give brown sugar every day: milk powder (mass ratio is 2:1) as food, tap water as drinking water. The culture temperature was maintained at 25°C and cultivated under natural light. Use a cloth bag to wrap the attractant as an egg collector to collect fly eggs.

[0042] The combined culture medium contains the following components in mass percentage: 40% of wheat bran, 20% of corn flour, 20% of soybean meal, and 20% of whole plant green corn. Prepare 1000g according to the proportion, add 700g of water, stir evenly, inoculate 0.1g fly eggs, culture at 25°C, stir the medium every 6 hours, put the medium and fly maggots into an oven at 60°C for drying on the fifth day. The dried fly maggots and culture medium are pulverized and passed through a pellet press to make pellet feed.

Embodiment 3

[0050] A kind of fly maggot protein feed, its preparation method comprises the steps:

[0051] Housefly (Muscadomestica) seed flies were cultivated in sarongs at a density of 5 cm 3 / Only. Give brown sugar every day: milk powder (mass ratio is 1:2) as food, tap water as drinking water. The culture temperature was maintained at 27°C and cultivated under natural light. Use a cloth bag to wrap the attractant as an egg collector to collect fly eggs.

[0052] The combined culture medium contains the following components in mass percentage: 70% of wheat bran, 10% of corn flour, 10% of soybean meal powder, and 10% of rice straw powder. Prepare 1000g according to the proportion, add 1kg of water, stir evenly, inoculate 2g of fly eggs, culture at 27°C, stir the medium every 6 hours, put the medium and fly maggots into an oven at 70°C for drying on the fifth day. The dried fly maggots and culture medium are pulverized and passed through a pellet press to make pellet feed.

Abstract

The invention discloses a method for preparing protein feed and a protein feed additive by culturing fly maggots with a defined medium. The fly maggot protein feed is prepared through the steps that the defined medium is inoculated with cyclorrhapha flyblows, culturing is performed for 2-6 days, and then drying is performed; the defined medium is prepared from wheat bran, corn flour, soybean meal and plant fiber powder. According to the method, the fly maggots cultured by the defined medium are adopted as raw materials for preparing the protein feed and the protein feed additive, and therefore continuous breeding all year round can be achieved; the raw materials of the medium are all selected from agricultural leftovers and are high in yield and low in cost, and therefore long-term breeding can be achieved; the defined medium used in the formula is comprehensive and balanced in nutrition and meets the all-aspect fly maggot growth requirements that carbohydrate and an appropriate amount of grease are supplied to fly maggot growth, and maggot protein obtained through culture is beneficial for digestion and absorption of livestock and aquatic animals.

Description

technical field [0001] The invention specifically relates to a method for cultivating fly maggots with a combined medium to prepare protein feed and protein feed additives. Background technique [0002] Protein is an essential nutrient for organisms to maintain life and growth. It not only participates in the composition of body tissues, but also is the main component of certain metabolically active substances (hormones, enzymes, immune antibodies), and is also the largest proportion of feed costs. With the rapid development of my country's aquaculture and feed industry, the shortage of protein raw materials has become increasingly prominent and has become one of the bottlenecks restricting the development of the entire aquaculture industry. Taking fish meal as an animal protein source as an example, its price has been rising steadily since 2008, which has greatly increased the cost of feed and breeding, and seriously restricted the sustainable development of the breeding in...
