Specific fingerprint rice bran extract-containing aquatic animal feed additive, preparation method thereof and formula feed containing additive

Abstract

The invention discloses a specific fingerprint rice bran extract-containing aquatic animal feed additive. The additive contains 3 percent of rice bran extract in percentage by mass. A fingerprint of the rice bran extract comprises the following components in percentage by mass: 5.0 to 10.0 percent of docosyl alcohol, 5.0 to 10.0 percent of lignoceryl alcohol, 5.0 to 15.0 percent of hexacosyl alcohol, 50.0 to 70.0 percent of octacosanol, 10.0 to 30.0 percent of triacontanol and 1.0 to 5.0 percent of dotriacontanol. The invention also discloses a preparation method of the aquatic animal feed additive, and formula feed containing the aquatic animal feed additive. The growth rate of aquatic animals is improved by 7 percent or more; anti-nitrite stress resistance to anoxia of carassius auratus var pengze is obviously improved, anoxia-resistant time is prolonged by 30 percent or more, and the death rate under an anoxic condition during fish transportation and the like can be reduced; lipid metabolism of fish bodies is greatly improved, low-density lipoprotein cholesterol is reduced by 19 percent or more, and high-density lipoprotein cholesterol is increased by 8 percent or more; and breeding safety is improved, and the feed additive is safe and effective green aquatic animal feed.

Description

technical field [0001] The invention relates to an aquatic feed additive, in particular to an aquatic feed additive containing a rice bran extract with a specific fingerprint and a preparation method thereof. The invention also relates to formula feed containing the aquatic feed additive. Background technique [0002] Rice bran has abundant resources in my country, and it is cheap and easy to get. The main active ingredient of rice bran extract is octacosanol, which also includes docosanol, tetracosanol, hexacosanol, triacontanol , Tricosanol and other higher carbon alcohols. The application of octacosanol in a very small amount can show its active effect, which can enhance physical strength, energy and endurance, improve stress ability, response sensitivity and body metabolic rate, improve myocardial nutrition, body oxygen utilization rate, reduce serum cholesterol and Triglyceride content and systolic blood pressure and other functions.

Problems solved by technology

However, there are few reports on rice bran extract polyalkanol compound as an aquatic feed additive. In addition, there is no research on the correlation between fingerprints and active efficacy. The difference in the compound ratio during use is very easy to cause the use of The effect is unstable, and it is very difficult to promote the application
