Background technology
Macrobrachium rosenbergii originates in the India Pacific region, lives in various types of fresh water or degree of saltiness water waters, since the sixties, successively move support in the Asia, some countries and regions such as Europe, America.Mainly promoted cultivation in more than 10 province in south (city, district) at present from Japan introduction China in 1976, the fastest with Development In Guangdong Province.The every hectogram shrimp of Macrobrachium rosenbergii contains protein 20.6 grams, fat 0.7 gram, and contain multivitamin and the necessary trace element of human body, be the high-protein nutrient aquatic products.Macrobrachium rosenbergii has that growth is fast, the culture-cycle is short, individuality is large, the economic worth advantages of higher, is a kind of good freshwater aquiculture object.At present, Macrobrachium rosenbergii has formed the scale cultivation in China, and the Macrobrachium rosenbergii industrial seedling rearing also achieves notable results, but the larval culture phase with become the shrimp aquaculture process in some diseases occurs often.That Chinese herbal medicine has is antibiotic, antiviral, improve immunity of organisms and improve the effect of growth of animal performance, can effectively reduce the aquaculture pollution that the metabolin discharging causes, and raw material sources are wide, cheap, it is the feed addictive of a kind of green, high-efficiency environment friendly, therefore can consider in the Macrobrachium rosenbergii feed, to add, thereby reach the purpose that improves Macrobrachium rosenbergii immunity.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of Chinese herbal feed additive that improves the Macrobrachium rosenbergii immunity of prawn.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of Chinese herbal feed additive that improves Macrobrachium rosenbergii immunity comprises rough gentian, golden cypress, dried orange peel, the bark of official magnolia, rheum officinale, Poria cocos, the root of large-flowered skullcap, the Radix Astragali.
Preferably, the Radix Astragali of the root of large-flowered skullcap of the Poria cocos of the rheum officinale of the bark of official magnolia of the dried orange peel of the golden cypress of the rough gentian of described Chinese herbal feed additive: 5-6%, 5-6%, 5-6%, 4-5%, 4-5%, 5-6%, 4-5%, 5-6%, 60% maize cob meal mix and cross after crushed 100 mesh sieves and be prepared from.
Beneficial effect of the present invention is: 1) use in the Macrobrachium rosenbergii feed as feed addictive, addition only is 0.5-1%; 2) obviously strengthen the immunity of organisms of Macrobrachium rosenbergii, effectively prevent the generation of disease in the Macrobrachium rosenbergii breeding process; 3) the present invention for the palatability of feed without any harmful effect; 4) pollution-free, noresidue is without any side effects, safety and environmental protection; 5) raw material sources among the present invention are wide, and are cheap, and production and processing technology is simple.
