Feed additive capable of preventing and treating large yellow croaker fatty liver

Abstract

The invention discloses two feed additives for preventing and controlling fatty liver of pseudosciaena crocea, which comprise two formulas and weight contents, wherein one formula comprises the following components in percentage by weight: 35 to 45 percent of betaine, 5 to 10 percent of L-carnitine, 3 to 5 percent of VE, 10 to 15 percent of Bupleurum falcatum, 8 to 12 percent of Salvia Miltrorrhiza and 25 to 30 percent of Herba Artemisiae Scopariae; and the other formula comprises the following components in percentage by weight: 25 to 35 percent of betaine, 5 to 10 percent of L-carnitine, 10 to 15 percent of VE, 10 to 15 percent of Bupleurum falcatum, 8 to 12 percent of Salvia Miltrorrhiza and 25 to 30 percent of Herba Artemisiae Scopariae. The additives can promote internal fat metabolism of pseudosciaena crocea, and reduce fat accumulation in the liver of pseudosciaena crocea. In addition, when the pseudosciaena crocea shows slight fatty liver tendency, the additives can help to recover the liver health of the pseudosciaena crocea to a certain extent.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing and treating fatty liver of large yellow croaker. Background technique [0002] Large yellow croaker [Pseudosciaena crocea (Richardson)] is an important economic fish in my country. Due to overfishing, the production has declined sharply. In 1987, the artificial breeding of large yellow croaker in my country was successful and in 1994, artificial breeding began. However, the body size of farmed large yellow croaker is poor, and the taste and nutritional value of fish meat are far inferior to those of wild large yellow croaker (Duan Qingyuan et al., 2000). A large number of studies have shown that excessive fat deposition is one of the important factors affecting body shape and taste (Miao Furong et al. 2008; Xu Jilin et al., 2005). Moreover, due to a large amount of fat deposition during the breeding process, the high incidence of fatty liver has seriously affec...

Problems solved by technology

However, the body size of farmed large yellow croaker is poor, and the taste and nutritional value of fish meat are far inferior to those of wild large yellow croaker (Duan Qingyuan et al., 2000). A large number of studies have shown that excessive fat deposition is one of the important factors affecting body shape and taste (Miao Furong et al. 2008; Xu Jilin et al., 2005)

Moreover, due to a large amount of fat deposition in the breeding process, the high incidence of fatty liver has seriously affected the growth rate of large yellow croaker and the economic benefits of farming (Liu Zhenyong et al., 2007; Zeng Duan et al., 2008), restricting the sustainable development of large yellow croaker farming
