Micropterus salmoides feed with liver protecting and body shape and color improving functions and preparation method thereof

Abstract

The invention discloses a micropterus salmoides feed with liver protecting and body shape and color improving functions. The micropterus salmoides feed with the liver protecting and body shape and color improving functions is composed of, by weight part, 24-40 parts of Peruvian fishmeal, 12-20 parts of bean pulp, 5-15 parts of peanut bran, 8-10 parts of corn gluten meal, 2-5 parts of spray-dried animal blood cells, 15-20 parts of high-gluten flour, 1-3 parts of squid visceral ointment, 2-3 parts of yeast cream, 0.5-2 parts of monocalcium phosphate, 1-2 parts of fish oil, 1-2 parts of soybean oil, 1-2 parts of soybean lecithin, 0.1-0.2 part of vitamin premix, 0.2-0.5 part of mineral premix and 1.3-4.3 parts of functional additives, wherein the functional additives are composed of spiral seaweeds, bile acid, curcumin and taurine. The preparation method of the micropterus salmoides feed with the liver protecting and body shape and color improving functions comprises weighing, mixing, extrusion expanding and pelleting, drying, oil spraying, cooling and packaging. Compared with the prior art, the prepared micropterus salmoides feed with the liver protecting and body shape and color improving functions can significantly improve the growth performance, the liver health status and the body shape and color of micropterus salmoides.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a California perch feed with functions of protecting the liver and improving body shape and color and a preparation method thereof. Background technique [0002] Since California perch was introduced to China in the 1990s, due to its special nutritional needs, compound feeds have not made a major breakthrough. Large, many diseases and other shortcomings. At present, most of the feeds on the market have problems such as no feeding during high temperature periods, slow growth, high mortality, poor body shape, and unnatural body color. After research, it was found that this series of problems were mainly caused by liver lesions, among which unreasonable feed ratio and lack of liver-protecting factors were the main reasons. [0003] content of the invention [0004] In order to overcome the problems that the existing California perch feed has no feed during high temperature period, slow...
