Abstract

The invention discloses a freshwater fish feed additive and a production method thereof. According to the feed additive provided by the invention, components are prepared reasonably, processing is convenient, cost is lower, and decomposition speed is high; decomposition speed and utilization speed of urea in the feed additive are coordinated, ammonia poisoning caused by ammonia accumulation in blood is avoided, and the defect of poor palatability of conventional feed is overcome; the feed additive is ground by a colloid grinder, emulsion is formed and dried in a spray dryer at the normal temperature to form microspheres, microspheres are taken as the feed additive, and powder, granules, tablets or capsules can also be prepared from the microspheres; the feed additive is applicable to aquatic creatures such as freshwater fish, shrimps and the like.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal feed, and in particular relates to a freshwater fish feed additive and a production method thereof. Background technique [0002] Utilizing the characteristics of ammonia available to microorganisms in freshwater fish, non-protein nitrogen is often used in freshwater fish 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 fish 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 microorganisms i...
