Freshwater shrimp feed additive and production method thereof

Abstract

The invention discloses a freshwater shrimp feed additive and a production method thereof, and aims to provide the feed additive which is reasonable in component preparation, convenient to process, low in cost and high in decomposition speed. The decomposition speed of the feed additive coordinates with the utilization speed of the feed additive, so that ammonia poisoning caused by accumulated ammonia in blood is avoided, and besides, the defect of poor palatability of a conventional feed is overcome. The freshwater shrimp feed additive is prepared from the following components of calcium carbonate, fish meal, corn starch and a coating material. The preparation technology comprises the following steps of uniformly dispersing the raw materials in a coating material solution, and performing grinding to obtain an emulsion; and drying the emulsion in a drier to obtain microspheres, wherein the microspheres are used as the feed additive and can also be prepared into powder or granules, tablets and capsules; the feed additive is suitable for aquatic organisms such as freshwater shrimps, lobsters and the like.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal feed, in particular to a green shrimp feed additive and a production method thereof. Background technique Background technique [0002] Utilizing the characteristics of ammonia available for microorganisms in freshwater shrimp, non-protein nitrogen is often used in freshwater shrimp feed instead of protein feed to save protein resources. Fishmeal has the advantages of high nitrogen content and low production cost, and is a non-protein nitrogen source worthy of further development. Studies have shown that fishmeal feed can make microorganisms grow and multiply rapidly. After feeding, freshwater shrimp can significantly increase feed intake by 15-20%, and improve digestibility by 20%. However, after the fish meal enters, it will be hydrolyzed rapidly, and ammonia will be released immediately, and enter the blood through the body, and its release rate often exceeds the utilization rate of m...

Problems solved by technology

[0003] In order to solve the above deficiencies, the object of the present invention is to provide a freshwater shrimp feed additive and its production method. The decomposition speed of the feed additive is coordinated with the utilization speed, so as to avoid ammonia poisoning caused by the accumulation of ammonia in the blood, and at the same time solve the problem of poor palatability of conventional feed. shortcoming
