Problems solved by technology

In the traditional utilization process of some economic crops and Chinese herbal medicines, parts such as stems and leaves are often discarded and cannot be used, but the active ingredients of these parts are no less than the medicinal parts and edible parts, so these plant wastes are used to develop Chinese herbal medicine extracts that can improve shrimp immunity and disease resistance, replace the use of antibiotics, and have easy-to-obtain raw materials and low prices will become a research hotspot

Abstract

The invention relates to the field of aquaculture, in particular to a plant extract composition for resisting vibriosis and its preparation method and application. In parts by weight, the plant extract composition is composed of 20-60 parts of the stem and leaf extract of Yizhi, 20-50 parts of the stem and leaf extract of galangal, 10-30 parts of the olive leaf extract, and 10-30 parts of the mango leaf extract. composition. The research of the present invention found that adding the above-mentioned plant extract composition to the feed can significantly improve the cultured survival rate of Litopenaeus vannamei, promote growth, enhance the activity of immune enzymes and antioxidant capacity in the hepatopancreas, and improve the survival after Vibrio infection The raw materials in the present invention are the by-products of economic crops and Chinese herbal medicine planting, which are cheap and easy to get, simple in process, and environmentally friendly.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a plant extract composition for resisting vibriosis and its preparation method and application. Background technique [0002] There are many types of shrimp cultured in my country, mainly including Litopenaeus vannamei, Penaeus monodon, Penaeus japonicus, Procambarus clarkii, red crayfish, Macrobrachium rosenbergii, Macrobrachium japonicus, etc. my country is the main breeding country of shrimp and also the largest consumer. It needs to import a large amount from Vietnam, Thailand, Ecuador and other countries every year to meet the growing demand of the domestic people. [0003] In recent years, the domestic shrimp farming industry has always had the problems of easy disease of shrimp seedlings, low breeding success rate, and lack of efficient functional compound feed. In the 13 years from 2003 to 2015, although the domestic production of Litopenaeus vannamei increased from 610,000 to...
