Herbivorous fish feed and preparation method thereof

Abstract

The invention discloses an herbivorous fish feed and a preparation method thereof. The herbivorous fish feed comprises the following components in parts by weight: 10-15 parts of duckweed, 20-25 partsof bean cake, 15-18 parts of wheat bran, 5-8 parts of rapeseed, 3-6 parts of water hyacinth, 3-6 parts of potamogeton wrightii morong, 10-12 parts of goosegrass wiregrass, 6-8 parts of cemetery grass, 6-8 parts of barnyard grass, 3-6 parts of dandelion, 2-5 parts of auxin and 1 part of a traditional Chinese medicine combination additive, wherein the traditional Chinese medicine combination additive further comprises the following traditional Chinese medicine raw material medicines: 2-6 parts of cyrtomium fortunei, 3-5 parts of folium isatidis, 1-4 parts of oldenlandia diffusa, 5-8 parts of wild chrysanthemum flowers, 2-4 parts of andrographis paniculata, 3-6 parts of radix isatidis, 5-10 parts of cane sugar, 3-8 parts of rheum officinale, 5-10 parts of corn flour and 6-10 parts of radix paeoniae alba. The herbivorous fish feed meets the requirements of intensive and large-scale production of the current aquaculture industry, forms the compound preparation from the feed raw materials according to a certain ratio, has the improved sinking property and the improved adhesiveness, is beneficial to growth and breeding of herbivorous fishes, and has good economic benefits and social benefits.

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] Fish feed is a key factor affecting fish farming, and it must also be developed in the direction of safe and environmentally friendly feed. During the production of hard pellet feed, the degree of gelatinization of starch is low, resulting in poor water resistance of the final product. However, fish feed has relatively high water resistance requirements, so it is particularly important to improve the water resistance of fish feed. Changes in various factors during processing have a greater impact on feed quality, especially water resistance. Starting from the processing process to optimize the production process, improving the processing conditions is the most effective way to improve water resistance. [0003] The research on e...

AI Technical Summary

Problems solved by technology

[0003] The research on extrusion technology 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 high maintenance costs, 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
