Feed for juvenile prawns and preparation method thereof

Abstract

The invention discloses a feed for juvenile prawns. The feed comprises one or more selected from the following components: fish meal, wheat bran, bean cake, vinasse, yeast, a composite vitamin premix, a traditional Chinese medicinal composite additive, a mineral matter premix and a feed adhesive. Weight parts of the above mentioned components are as follows: 10 to 40 parts of fish meal, 10 to 20 parts of wheat bran, 10 to 15 parts of bean cake, 1 to 2 parts of vinasse, 1 to 2 parts of yeast, 1 to 2 parts of the composite vitamin premix, 1 to 2 parts of the traditional Chinese medicinal composite additive, 1 to 2 parts of the mineral matter premix and 10 to 15 parts of the feed adhesive. According to the invention, Chinese herbal medicines are applied to prevent and treat fish and prawn diseases, which is in accordance with disease controlling criteria for development of nuisanceless aquaculture and production of green aquatic products, especially in accordance with demands for intensive and large-scale production in the current aquaculture industry; the Chinese herbal medicines compose a compound preparation in proportion, which enables synergistic effects of the medicines 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 juvenile prawns.

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 juvenile shrimp feed and a preparation method thereof. Background technique [0002] The main factors affecting the quality of fish and shrimp 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 determining the quality of fish and shrimp bait. In addition to the selection of raw materials in accordance with conventional standards, it is more important to consider the digestive characteristics of the animals being reared. For fish and shrimp, their digestive system is not as good as that of terrestrial animals. When choosing raw materials, we must proceed from the digestion and absorption of fish and shrimp. at this point. Particularly noteworthy are two points: ① enzymatic treatment of r...

AI Technical Summary

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
