Abstract

The invention discloses a shrimp feed. The feed is composed of the following components in percentage by mass: 13%-16% of seaweed meal, 10%-13% of VC phosphate, 12%-15% of selenium dioxide, 11%-13% offish meal, 16%-20% of corn flour, 13%-17% of chitin and 14%-16% of yeast powder, wherein the sum of the mass percentages of all the components is 100%. The invention also discloses a preparation method of the shrimp feed. The method comprises the following steps: firstly, premixing the corn flour, the seaweed meal, the fish meal and the yeast powder, and performing uniform stirring at normal temperature to obtain a premix; carrying out ball milling on the VC phosphate, the selenium dioxide, the chitin and the premix to obtain a mixture; and granulating the mixture to obtain the shrimp feed. The shrimp feed disclosed by the invention has the characteristics of rich nutrition and high feed conversion rate.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a shrimp feed, and also relates to a preparation method of the shrimp feed. Background technique [0002] Shrimp meat has high nutritional value, and its meat is tender and easy to be digested and absorbed by the human body after processing. It is a good nutritious food for the elderly, sick, pregnant women and young children. Due to the rapid growth and development of shrimp and the strong metabolism in the body, shrimp needs to be fully supplied with protein, inorganic salts and vitamins. However, the existing feed is difficult to meet the production needs of meat shrimps, with poor taste and unbalanced nutrition. Contents of the invention [0003] The purpose of the present invention is to provide a shrimp feed, which has the characteristics of rich nutrition and high feed conversion rate. [0004] Another object of the present invention is to provide the p...
