A few days ago, the "Shrimp Feed Additive" completed by Researcher Li Zhuojia of the South China Sea Fisheries Research Institute and others was granted a national invention patent (Patent No. ZL200610122305.5), which made an important breakthrough in the research and development of shrimp probiotic immune function additives.

The main feature of the invention is that it is composed of 8-12 parts by weight of Chinese herbal medicine powder and 12-18 parts by weight of Bacillus licheniformis solid material, wherein the composite Chinese herbal medicine powder is composed of equal parts by weight of Radix Isatidis, Forsythia, Astragalus, Huoxiang, Sadawang and Rhizoma Coptidis are dried and pulverized into a compound. The Bacillus licheniformis flora in the Bacillus licheniformis composite solid material is 109CFU/g; the weight percentage of the compound additive added to the shrimp feed is 0.15%-0.50%, mixed After homogenization, granulation is made into granules with a particle size of 1.5mm.

This invention adds appropriate amount of Chinese herbal medicine and Bacillus licheniformis to shrimp feed. Through their synergistic effect, it can significantly increase the activity of digestive enzymes, promote the growth of prawns and increase the survival rate of prawns. This technology has been widely used in prawn farming and production. , It produces good economic and social benefits, is conducive to the sustainable and healthy development of shrimp farming, and is in line with the development strategy trend of aquatic feed.
