The special feed additive for sturgeon described therein is made from the following raw materials in parts by weight: 5 parts of phoenix grass, 4 parts of lobelia, 5 parts of forsythia, 4 parts of perilla, 8 parts of garlic, 7 parts of anise, and 4 parts of licorice 5 parts, 5 parts of Radix Paeoniae Alba, 10 parts of corn gluten powder; The preparation method of described special-purpose feed additive for sturgeon is: take each raw material by weight, at first take the Pteris vulgaris, lobelia, forsythia, forsythia, Seven kinds of traditional Chinese medicines such as perilla, garlic, anise, licorice and white peony are mixed and crushed to about 50 meshes, and then the Chinese medicine powder obtained by crushing is mixed...
Embodiment 2
[0027] Example 2 : A special compound feed for sturgeon, made of the following raw materials in parts by weight: 40% soybean meal, 20% sub meal, 25.5% fish meal, 7% fish oil, 6% sea shrimp meal, 0.3% salt, 0.2% choline, Sturgeon special feed additive 1.0%. Others are the same as embodiment 1.
Embodiment 3
[0028] Embodiment 3: animal breeding test
[0029] In a sturgeon artificial breeding base in Hubei, 1,000 artificially propagated and cultured Chinese sturgeons were selected as the breeding objects. They were the same batch of fish fry stocked in the same batch. They were divided into 5 groups of 200 fish in each group, and the same breeding mode was adopted for management. . Wherein group 1 is the control group, adopts commercially available imported sturgeon compound feed to raise; Group 2-3 is the experimental group, adopts the sturgeon special compound feed of the embodiment of the present invention 1, 2 to raise; Group 4-5 is contrast The test group was fed with the compound feed of the following comparative test examples 1 and 2, and the average survival rate and the growth during the breeding process were recorded. The specific results are shown in the following table 1:
