Problems solved by technology

In aquaculture animals, especially in the cultivation of high-value fish species in my country, such as Japanese eel and European eel, there are few reports on the research and application of lipase, which is mainly due to the development of digestive system in these farmed fish. In the process, there is a lack of differentiation of the stomach, and its digestive tract is mostly in a neutral environment, which is quite different from that of livestock and poultry, so the research and development of lipase suitable for it is much more complicated than that of livestock and poultry

Abstract

The invention relates to the field of feed additives, in particular to a feed additive for promoting growth of Japanese eel and enhancing immunity as well as a preparation method and application of the feed additive. The feed additive is prepared from the following components in percentage by weight: 10-20 percent of lipase (Lip2) produced by fermentation of Yarrowia lipolytica, 20 percent of emulsifier, 20-40 percent of bacillus amyloliquefaciens, 10 percent of vitamin E and the balance of carrier. The feed additive according to the invention remarkably improves the growth performance and thedisease resistance of the Japanese eel, and thus the economic benefit of a Japanese eel breeding enterprise is remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for promoting the growth of Japanese eel and improving immunity, its preparation method and application Background technique [0002] Lipase, also known as triacylglycerol acyl hydrolase, is a class of enzymes that decompose and synthesize fat. It can not only catalyze ester hydrolysis, but also catalyze ester synthesis and transesterification. Lipase is a kind of digestive enzyme. Exogenous fat needs to be digested and decomposed into free fatty acid, glycerol and monoglyceride before it can be used by animals. The storage and use of fat in the body is also indispensable for lipase. Lipase also participates in intracellular lipid metabolism. In recent years, lipase has been widely used in livestock and poultry feed because of its unique physiological functions and effects. In aquaculture animals, especially in the cultivation of high-value fi...
