Shrimp feed and preparation method thereof

Abstract

The invention discloses a shrimp feed and a preparation method thereof. The feed comprises the following raw materials in percentage: 2.5% of silkworm dropping, 10% of rice bran, 10% of wheat bran, 48% of fish meal, 10% of soybean cake, 2% of beer yeast, 1% of traditional Chinese medicine composition additive, 0.5% of vitamin complex premix, 1% of mineral premix and 15% of feed adhesive. The invention in which Chinese herbal medicines are used for preventing and treating fish and shrimp diseases completely meets the disease control criteria of developing nuisance free aquaculture and producing green marine products, and especially meets the requirements of intensive and large-scale production in the current aquiculture; the Chinese herbal medicines in a certain proportion are prepared into a compound preparation to better play the synergistic effect of the medicines; starch in the feed adhesive is conglutinated at different temperatures by a steaming process, thus increasing the degree of expansion and greatly improving the degree of gelatinization of the starch; and the feed adhesive can completely replace a chemical adhesive on effect in feed processing, improves the sinking property and adhesiveness of the feed, and benefits the shrimp growth and culture, thus creating good economic benefit and social benefit.

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 shrimp feed and a preparation method thereof. Background technique [0002] In the classification system, shrimps belong to Arthropoda, Crustacea, Decapod, and Swimming suborder. There are many types of shrimp, mainly Penaeus vannamei, Penaeus sinensis, Penaeus japonicus, Penaeus monodon, Macrobrachium rosenbergii, Penaeus lanceolata, etc. Our country has a vast sea area, numerous rivers and lakes, and is rich in sea shrimp and freshwater shrimp. Shrimp is deeply loved by consumers because of its fresh and tender meat and rich nutrition. Especially in recent years, along with the rapid development of my country's economy and the continuous improvement of people's living standards, various shrimp products have gradually entered the table of common people. At the same time, the rise of tourism and the growth of for...

Problems solved by technology

The disadvantages in the production process of extruded feed are: (1) high equipment investment cost and high maintenance cost; (2) in the process of producing sinking feed, the material is easy to expand, resulting in a decrease in density, and the final product is easy to become buoyant (3) The high temperature in the extrusion process destroys some heat-sensitive nutrients such as VC and various feed enzymes, resulting in nutritional imbalance

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 shrimp 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 shrimp feed increases, which leads to an increase in the cost of shrimp farming; 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
