Feed for herbivorous fishes and preparation method thereof

Abstract

The invention discloses a feed for herbivorous fishes. The feed comprises one or more selected from the group consisting of bone meal, wheat bran, bean cake, rice bran, rapeseeds, a composite vitamin premix, a traditional Chinese medicinal composite additive, a mineral matter premix and a feed adhesive. The traditional Chinese medicinal composite additive further comprises the following traditional Chinese medicine bulk drugs: dyers woad leaves, common andrographis herb, Indian bread, root of large-flowered skullcap, weeping forsythia capsule, patrinia herb, curcuma tuber, heartleaf houttuynia herb, Chinese magnoliavine fruit, red sage root, dodder seeds, tangshen, milkvetch root, heydyotis and white peony root. According to the invention, the feed for herbivorous fishes is in accordance with demands for intensive and large-scale production in the current aquaculture industry; a compound preparation is prepared from raw materials for the feed according to a certain proportion, which enables synergistic effects of the bulk drugs in the traditional Chinese medicinal composite additive to be better performed; a steaming process is utilized to allow starch in the feed adhesive to agglutinate at different temperatures, so the degree of expansion is increased, the degree of gelatinization of the starch is substantially improved, the effects of a chemical adhesive in feed processing can be totally replaced, and sinking performance and binding performance of the feed are enhanced, which is beneficial for growth and culture of herbivorous fishes and enables good economic benefits and social benefits to be created.

Description

technical field [0001] The invention relates to a feed produced by using animals and plants as raw materials and a preparation method thereof, in particular to a herbivorous fish feed and a preparation method thereof. Background technique [0002] Herbivorous fish are represented by grass carp and catfish. These fish inhabit rivers and lakes in the plains, and generally prefer to live in the middle and lower layers of the water and areas with many aquatic plants near the shore. It is lively, swims quickly, and often looks for food in groups. A typical herbivorous fish. Because of its rapid growth and wide source of feed, it is one of the four major domestic fish in freshwater farming in China. The main factors affecting the quality of fish bait are: ① raw material quality; ② processing technology and equipment; ③ equipment operation and management; ④ formula design. The quality of raw materials is the primary factor in determining the quality of fish bait. In addition t...

Problems solved by technology

[0005] The research on extrusion technology in my country is mainly concentrated in the field of food processing and the pretreatment of feed raw materials. The production of extruded fish feed is still in its infancy. On the one hand, due to the relatively expensive extrusion machinery and the high maintenance cost, resulting in The production cost of fish feed increases, which leads to the increase of fish farming cost; on the other hand, due to the existence of various controllable factors and interference factors in the extrusion process, changes in these factors have a greater impact on product quality

If various factors cannot be effectively controlled in a timely manner during the production process, it will be difficult to ensure the stability of the production process and the quality of the final product
