Problems solved by technology

[0003] At present, the existing compound feeds are mainly fish oil feed and high-fat feed. However, due to the decrease in fish oil production in recent years, the price of fish oil feed has skyrocketed, and high-fat feed has been widely valued because of its protein saving effect. After feeding, it is very easy to lead to abnormal deposition of fat in the liver of large yellow croaker, which in turn leads to the occurrence of unfavorable situations such as reduced feed utilization rate, prone to disease, increased mortality and slowed growth

Abstract

The invention provides a feed additive for larimichthys crocea, compound feed and a preparation method of the compound feed, as well as application of the feed additive or the compound feed. The feedadditive is mainly prepared by dissolving taurine, choline chloride and betaine dissolved in bile acid. By compounding the bile acid, the taurine, the choline chloride and the betaine to prepare the feed additive, the digestive absorption of the larimichthys crocea fat can be effectively promoted, and the phenomenon of abnormal deposition of liver fat is effectively prevented while the fat contentof the larimichthys crocea is increased. In addition, the preparation method of the compound feed provided by the invention has the advantages of being simple to operate, mild in conditions, environment-friendly in the whole preparation process, and capable of providing a more feasible way to breed the larimichthys crocea with better quality.

Description

technical field [0001] The invention relates to the technical field of fish breeding feed, in particular to a feed additive for large yellow croaker, a compound feed and a preparation method and application thereof. Background technique [0002] Large yellow croaker is the marine cultured fish with the largest aquaculture output in my country. In 2017, the total national output reached 177,600 tons, an increase of 11.35% year-on-year. At present, the breeding and feeding of large yellow croaker is still mainly chilled fish, but the penetration rate of compound feed has reached 30%. With the systematic deepening of large yellow croaker nutrition research in recent years, the special compound feed for large yellow croaker has been successfully developed and put on the market, and the use of compound feed has been more and more recognized by the market. The popularity of feed in large yellow croaker farming will accelerate. [0003] At present, the existing compound feeds are...
