Embodiment Construction

[0022] The following are preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also considered as the present invention. protection scope of the invention.

[0023] In the following examples, the corosolic acid used comes from Shanghai Yuanye Biotechnology Co., Ltd.

[0024] In order to further verify the influence of the feed additive provided by the invention on the growth performance of fish, the invention verifies a series of indicators such as the growth performance of grass carp by adjusting the ratio of the additive in the feed. Specifically, casein, maltodextrin, corn oil, cod liver oil, inorganic salt mixture and vitamin mixture are used to make the basic feed, corn oil and cod liver oil are used to make the corresponding high-fat feed, and 1% of the mass ...

Abstract

The invention relates to the technical field of feed additives, in particular to application of corosolic acid in preparation of feed for preventing and/or treating fish fatty liver and improving fish immunity. When the corosolic acid is specifically applied, the corosolic acid is used as a feed additive, the addition amount is 0.005-0.20%, and the corosolic acid is directly mixed with fish feed. The corosolic acid is applied to prevention and/or treatment of fish fatty liver, and the corosolic acid is mainly characterized in that the immunity of fish can be enhanced, the morbidity of fish fatty liver and liver and gall syndrome can be reduced, the utilization rate of aquatic feed can be increased, the intestinal micro-ecological environment of fish can be adjusted, and the growth performance of fish can be improved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the application of corosolic acid in the preparation of feed for preventing and / or treating fish fatty liver. Background technique [0002] In the modern intensive aquaculture method, in order to obtain higher economic benefits, the oil content in the aquatic feed is constantly increasing, and the excessive accumulation of fat in the cultured fish is becoming more and more serious, causing fish "fatty liver", Lipid metabolism disorders such as hepatobiliary syndrome. [0003] Unlike mammals, fish lack a subcutaneous fat layer, and their main fat accumulation sites are abdominal mesenteric adipose tissue, liver and muscle. The excessive accumulation of excess fat in the abdominal cavity causes the problem of "big belly", and the excessive accumulation of excess fat in the liver causes the problem of fatty liver. The accumulation of fat will cause the nutritional metabolis...
