Problems solved by technology

There are two problems in the feed produced by this method: one is that there are potential safety hazards in the product, and the fly maggots raised with animal feces are easy to carry germs and can contaminate animals. Transferred to animals; on the other hand, untreated fly maggot protein has a low digestibility and absorption rate in animals
In this patent, the feeding cost of fly maggots is relatively high, and it is difficult to produce on a large scale
[0007] The above methods are to process fly maggots into feed, and the digestion and absorption rate of fly maggot protein without technical treatment is low in animals.
In addition, there is no report on the use of biotechnology methods to convert aquatic product processing waste into fly maggot protein and feed additives

Embodiment 1

[0040] Example 1: Preparation of Feed Additives Using Shrimp Processing Waste to Raise Fly Maggots

[0041] (1) Take 1 ton of fresh shrimp processing waste, crush it into 60 meshes, then carry out conventional sterilization, fully mix the raw materials and water in a ratio of 5:1 by weight, insert 7% of the rejuvenated composite bacteria, The composite bacteria are Lactobacillus acidophilus, Saccharomyces cerevisiae and Bacillus subtilis with a weight ratio of 1:1:1. At the same time, 60 kg of molasses is added and stirred evenly. hour, the fermented material is baked to semi-dry and wet (advisable with humidity 60%~65%), and the actual fly maggot food is about 600 kilograms;

[0042] (2) put into 6 centimeters of thick fly maggot food earlier in the fly maggot pool, mix 1g fly ovum ratio by 1kg food material, at humidity 65%, cultivate 3 days under 32 ℃ of temperature, fly maggot is separated with compost, can Obtain about 380 kg of fly maggots;

[0043] (3) Place the isola...

Embodiment 2

[0045] Embodiment 2: Making use of tilapia processing leftovers to raise fly maggots to prepare feed additives

[0046] (1) Take 1 ton of fresh tilapia processing waste, crush it into 80 meshes, and then carry out conventional sterilization, fully mix the raw materials and water in a ratio of 5:1 by weight, and insert 5% rejuvenated compound Bacteria, the composite bacteria are Lactobacillus acidophilus, Saccharomyces cerevisiae and Bacillus subtilis with a weight ratio of 1:1:1. At the same time, add 60 kg of molasses and stir evenly. After adjusting the pH to 6.0, place it in a constant temperature fermentation tank at 30°C Ferment for 52 hours, bake the fermented material to a semi-dry and wet state (preferably with a humidity of 60% to 65%), and obtain about 600 kg of actual fly maggot food;

[0047] (2) put into 4 centimeters of thick fly maggot food material earlier in the fly maggot pool, mix 1g fly ovum ratio by 1kg food material, at humidity 70%, cultivate 4 days unde...

Abstract

The invention discloses an immune feed additive, which is prepared from maggots, wherein the maggots are fed with fermented leftovers from aquatic product processing by enzymolysis. The invention also provides a method for preparing the immune feed additive, which comprises the following steps: 1, fermenting the leftovers from aquatic product processing; 2, feeding maggots with the fermented leftovers from aquatic product processing; 3, performing the enzymolysis of the maggots to obtain the immune feed additive. The feed additive provided by the invention contains rich nutrients and functional elements and can promote growth and obviously improve immunity and pathogenic bacterium resistance in animals; therefore, the feed additive is a high-efficiency immune feed additive. The preparation method of the feed additive adopts a biological technique, avoids producing any waste in a production process, and is green, environmentally-friendly, simple in process, high in maneuverability and capable of allowing for large-scale production.

Description

technical field [0001] The invention relates to the fields of feed industry and breeding industry, in particular to a feed additive capable of significantly improving animal body immunity and a preparation method thereof. Background technique [0002] Feed additive is an indispensable key substance to realize the full price nutrition of animals. It has been widely used in livestock, poultry and aquaculture. However, with the development of feed additive industry, the impact of some feed additives on the quality of animal products, environmental pollution and human, The hazards to animal health are becoming more and more obvious. In recent years, the safety incidents of aquatic products and livestock products at home and abroad have occurred frequently, and people began to find it difficult to accept the use of additives in the breeding industry, which will undoubtedly affect the healthy development of the feed industry and the breeding industry. The development of new green...
