Embodiment Construction

[0016] In order to have a clearer understanding of the present invention, further description will be made below in conjunction with the best embodiments and accompanying drawings.

[0017] Referring to the accompanying drawings, the made feed core has a cylindrical shape. For the sake of clarity, the figure is enlarged and the core 1 is represented by a double-dotted line. Most of the engineered fly extract layer 3 penetrates into the surface layer 2 of the core 1 , a small amount is located on the outer surface of the inner core. In the figure, the engineering fly extract layer 3 is represented by a thick solid line, that is, in the section, only the area surrounded by the thick solid line contains the engineering fly extract.

[0018] The preparation method of above-mentioned prawn feed adopts following method:

[0019] The selected raw material components and weight are as follows: 260 kg of high-gluten flour; 4 kg of peanut bran; 90 kg of soybean meal; 50 kg of shrimp she...

Abstract

A biologic feed for prawn is composed of granular kernel and extract of engineering fly as external layer. It is prepared from the raw materials used by existing feed through pulverizing, removing impurities, stirring, modifying, die pressing, heating, baking, cooling to obtain the said granular kernel, and slow settling airflow drying to coat the internal kernel with atomized extract of engineering fly. It can improve the immunity of prawn to diseases and viruses, and accelerate growth of prawn as it is rich in amino acids and trace elements.

Description

technical field [0001] The invention relates to a special biological feed for prawns and a preparation method of the feed, in particular to a prawn feed rich in cecropin-like antibacterial protein, metallothionein and lysozyme and a preparation method thereof. Background technique [0002] There are many kinds of feeds used in artificial feeding of prawns. Usually, the main ingredients that can be used are high-gluten flour, soybean meal, fish meal, shrimp shell powder, yeast, phospholipid oil, fish oil, calcium dihydrogen phosphate, VC, squid paste, choline, etc. Using peanut bran, blood meal, squid powder, prawn minerals, adhesives, micro-treasures, prawn vitamins, growth promoters, karamic acid, carnitine, etc., according to different prawn species, rationally configure different components and weight ratios, after The pulverizer crushes the raw materials; the vibrating screen removes impurities from the sand and gravel in the raw materials, and the permanent magnetic cyl...
