The invention discloses a
sea cucumber culturing
feed additive and a preparing and using method thereof. The
feed additive is prepared from medical stone and Chinese herbal medicaments, wherein the
mass mixing ratio of the medical stone to the Chinese herbal medicaments is 50-70:50-30; and the Chinese herbal medicaments comprise 30 to 50
mass percent of raidx astragali, 15 to 25
mass percent of Chinese angelica, 5 to 15 mass percent of common
andrographis herb, 5 to 15 mass percent of
honeysuckle flower, 5 to 15 mass percent of indigowoad leaf and 5 to 15 mass percent of fried scorch-fried
crataegus. The preparation method comprises:
grinding the components respectively; sieving the ground components with a 60 to 100 mesh
sieve; and feeding the ground components in ratio into a feed mixer to stir the components uniformly, wherein the required
coefficient of variation (CV) of mixing precision is less than 10 percent. The ratio of the
sea cucumber culturing
feed additive to the feed is 1:9, the feed additive is added into the feed, and the mixture is mixed uniformly and used in a
larva pool. The
sea cucumber culturing feed additive has the advantages of avoiding secondary
pollution, reducing
water exchange, effectively promoting the growth of sea cucumbers, improving the body
immunity and
disease resistance of the sea cucumbers, reducing the use of
antibiotics and chemical medicaments, along with widely available raw materials, safety, no
toxicity and convenient use.
