Silverfish raising feed and preparation method thereof

Abstract

The invention provides a silverfish raising feed and a preparation method thereof. The silverfish raising feed comprises an outer-layer part and an inner-layer part, wherein the outer-layer part is prepared from the following raw materials in parts by weight: 4-10 parts of bone meal, 4-7 parts of fish meal, 3-8 parts of silkworm chrysalis meal, 3-7 parts of feeding yeast, 4-6 parts of isatis root, and 3-8 parts of rapeseed oil residue; and the inner-layer part contains the fly pupae after high temperature and high pressure treatment or rotifera after high temperature and high pressure treatment. With the adoption of the silverfish raising feed, the survival rate of silverfish is greatly improved, and meanwhile, the burdening of the raw materials is reasonable, so that the silverfish can grow rapidly, and thus the raising value of the silverfish is improved.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a feed for whitebait feeding and a preparation method thereof. Background technique [0002] Whitebait (English: salangid) is a freshwater fish, found in saltwater and freshwater in East Asia, and is known as a delicacy in China. Slender, salmon-like, scaleless or with fine scales, whitebait can be divided into small whitebait and large whitebait, of which the large whitebait can grow to a length of about seven to ten centimeters, rarely longer than 15 centimeters (6 inches) . The mouth is large, the teeth are large and sharp, and it preys on fish. Whitebait is named for its slightly round body, tender and transparent, and silvery color. [0003] With the continuous improvement of people's living standards, people's requirements for diet are getting higher and higher. Not only the nutritional value of the ingredients is needed, but also the delicious meat quality of the ingr...

Problems solved by technology

[0004] The whitebait feed that is widely used now can make the whitebait grow rapidly to a certain extent, but the nutrition is not comprehensive enough, so that when the whitebait is fed in the juvenile stage, the whitebait grows rapidly, and the deliciousness of the meat cannot be guaranteed. The nutritional value will also be greatly reduced, and the growth cycle of whitebait in the juvenile stage is long, and the mortality rate is high
