A kind of compound feed specially used for cultivating giant snout-nosed catfish and its preparation method

Abstract

The invention discloses a compound feed specially used for cultivating giant-nosed globulus and a preparation method thereof, belonging to the technical field of aquatic animal feed. The key points of the technical solution of the present invention are: a special compound feed for the cultivation of giant snout globulus, which is prepared from the following raw materials in proportion by weight: 20% to 25% of fish meal, 25% to 30% of fermented soybean meal, 25% to 30% of fermented soybean meal, and chicory meal 10%~20%, secondary powder 10%~12%, calcium dihydrogen phosphate 1%, choline chloride 0.5%, multi-dimensional premix 0.5%, multi-mineral premix 0.5%, compound enzyme 0.5%, Chinese herbal medicine additive 1.0%, corn oil 3% and fish oil 1% to 3%. The preparation process includes the steps of raw material crushing, mixing and tempering, extrusion granulation, drying, external spraying and cooling packaging. The invention has the advantages of simple process, balanced nutrition, easy-to-obtain raw materials, and environmental protection, and is especially suitable for the physiological characteristics of the digestion of the groinfish. economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal feed, and in particular relates to a compound feed specially used for cultivating giant snoutfish and a preparation method thereof. Background technique [0002] Rhinogobio nasutus, also known as Tumoer, belongs to Cypriniformes, Cyprinidae, and Rhinogobio. It is mainly distributed in the Yellow River system in my country. It lives at the bottom of the water body and likes rapids. . [0003] The genus is an omnivorous fish, and mainly feeds on benthic animals, aquatic insects and algae in natural waters. As a large economic fish, its body color is bronze. The body length of wild caught fish can reach 43cm. It has the characteristics of fast growth, strong environmental adaptability, tender meat, few intermuscular spines, and rich nutrition. From a nutritional point of view, it is a high-protein, low-fat fish, rich in essential amino acids and polyunsaturated fatty acids, and can be used as...

Problems solved by technology

But at present, breeding is still in the stage of scientific research, and it is only scattered in places such as the Yellow River Basin in Ningxia. The breeding feed used is usually carp and other omnivorous fish feeds. Although they can also be eaten, the feed coefficient is high, the immunity is low, High cost of farming

As this cultured species moves from the R&D stage to the market, there is currently a lack of breeding-specific compound feeds for giant snub-nosed gudgeon in the market
