Abstract

The invention discloses a special compound high-quality feed additive for freshwater shrimps. The special compound high-quality feed additive for the freshwater shrimps is prepared from the following substances in parts by weight: 4-6 parts of L-carnitine tartrat, 5-8 parts of saccharicterpenin, 6-8 parts of limonin, 4-7 parts of a compound vitamin additive, 2-3 parts of beneficial bacteria, 10-15 parts of a Chinese herbal medicine additive, 8-10 parts of medical stones and 2-5 parts of trimethylamine oxide. Aiming at physiological properties and growth rules of the freshwater shrimps, the different components are selected to be combined to obtain the feed additive, so that the growth of the freshwater shrimps can be accelerated, and the immunological competence and anti-stress capability of organisms also can be improved; furthermore, the special compound high-quality feed additive also has the effects of adsorbing harmful substances, resisting diseases and sterilizing and purifying the water quality, and the growth environment of the freshwater shrimps is optimized; the product has harmless components and does not cause medicine residues and environment pollution; the yield and quality of the freshwater shrimps are commonly improved; and a production method is simple and the components are easy to obtain, so that the special compound high-quality feed additive has a very good popularization value.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special compound high-quality feed additive for freshwater shrimp and a preparation method thereof. Background technique [0002] Freshwater shrimp scientifically known as Macrobrachium nipponense (Macrobrachium nipponense), commonly known as river shrimp, is widely distributed in fresh water all over my country and has the characteristics of fast growth, strong fecundity, delicious taste and rich nutrition. Because of its convenient seed source, low breeding cost and relatively simple breeding technology, it has become a preferred species for farmers to raise shrimp. However, with the rapid development of the freshwater shrimp industry, on the one hand, the production of green shrimp farming has not been able to increase and cannot be compared with other shrimps; on the other hand, the frequent occurrence of green shrimp diseases has also caused great harm to the green shrimp f...

Problems solved by technology

However, with the rapid development of the freshwater shrimp industry, on the one hand, the production of green shrimp farming has not been able to increase and cannot be compared with other shrimps; on the other hand, the frequent occurrence of green shrimp diseases has also caused great harm to the green shrimp farming industry.

Ordinary growers usually choose to use hormones and drugs when facing these two problems. Long-term use of hormones and drugs will lead to drug resistance and harmful element residues in animals, and will cause adverse effects on the environment, which is not conducive to sustainable development
