Special feed for catfish and preparation method of special feed

Abstract

The invention mainly relates to a special feed for catfish. The special feed comprises a main material, an auxiliary material and an adhesive, wherein the main material is prepared from the following components: barley flour, soybean cake powder, wheat bran, soybean meal, green gram starch, brewer's grain, beef liver powder, bone meal, shrimp meal, crab shell powder, fish meal, earthworm powder, dried-powder of housefly larvae, silkworm chrysalis meal, silkworm feces and seaweed meal; and the auxiliary material is prepared from the following components: water melon seeds, galium aparine, ansu apricot leaves, folium isatidis, pine needle leaves, folium artemisiae argyi, citrus leaves, tobacco leaves, hippophae rhamnosides, dried strawberries, honeysuckle, radix isatidis, chrysanthemum indicum, hairyvein agrimony, luffa vines, stone-like omphalia, shaddock peel, flavedo, brucea javanica, poria cocos, polygonum cuspidatum and garlic. When the catfish is cultured by using the special feed for the catfish, the nutrient requirements of the catfish at various stages can be fully met, and fast growth of the catfish is promoted. Meanwhile, natural materials are adopted by the feed, so that the feed is high in security, the raw materials are easy to get, the feed does not have any toxic or side effect in the use process, no harmful substance is left, and thus the feed is an environment-friendly feed worthy of being popularized.

Description

technical field [0001] The invention relates to an aquatic feed, in particular to a special feed for catfish and a preparation method thereof. Background technique [0002] Catfish mainly live in the middle and lower layers of rivers, lakes, reservoirs, and ponds. They mostly move around along the coast. During the day, they hide under grass, rocks or deep water, and they forage frequently at night. Catfish is a carnivorous fish, and its prey objects are mostly small fish, which can be cultured artificially. Its growth rate is relatively fast, and some species can grow very large. Catfish is not only rich in nutrition like other fish, but also has tender meat, contains more protein and fat, and has a better therapeutic effect on people who are weak, weak and malnourished. Catfish is a good product for promoting lactation, and has the effects of nourishing yin and blood, nourishing qi, appetizing, and diuretic. It is a must-choice food for women's postpartum diet therapy. W...

Problems solved by technology

At present, the artificial feeding of catfish is mainly based on general-purpose artificial feed, and most of the feed ingredients are evolved from common fish breeding feed. Among them, the nutritional content for catfish is not very reasonable, and the content of various proteins and vitamins is relatively low. , it is easy to cause various nutritional deficiencies of catfish, especially after catfish enters the rapid growth period, because they cannot take in sufficient nutrients in time and effectively, resulting in slow weight gain, which reduces the production of catfish and fails to achieve the expected results
