Embodiment 1

[0014] The feed additive capable of improving the growth and immunity of sea cucumbers of the present invention comprises the following components: chitosan oligosaccharide, bacillus, astragalus, licorice and angelica. The mass ratio of each component is: chitosan oligosaccharide, bacillus, astragalus, licorice, angelica = 0.1-0.3: 0.1-0.3: 1-3: 1-3: 1-3.

[0015] The raw materials of the above-mentioned components are pulverized by the superfine pulverizer, and after passing through a 200-mesh sieve, they are mixed evenly according to the above-mentioned mass ratio to form a Chinese herbal medicine compound feed additive for sea cucumbers. The additive is added into the feed of sea cucumber, and the additive accounts for 0.5% of the total mass of the feed.

Embodiment 2

[0017] The feed additive capable of improving the growth and immunity of sea cucumbers of the present invention comprises the following components: chitosan oligosaccharide, bacillus, astragalus, licorice and angelica. The mass ratio of each component is: chitosan oligosaccharide: bacillus: astragalus: licorice: angelica=0.1:0.1:2:2:1.5.

[0018] The raw materials of the above-mentioned components are pulverized by the superfine pulverizer, and after passing through a 200-mesh sieve, they are mixed evenly according to the above-mentioned mass ratio to form a Chinese herbal medicine compound feed additive for sea cucumbers. The additive is added into the feed of sea cucumber, and the additive accounts for 0.5% of the total mass of the feed.

Embodiment 3

[0020] The feed additive capable of improving the growth and immunity of sea cucumbers of the present invention comprises the following components: chitosan oligosaccharide, bacillus, astragalus, licorice and angelica. The mass ratio of each component is: chitosan oligosaccharide: bacillus: astragalus: licorice: angelica=0.2︰0.2︰2︰2︰1.5.

[0021] The raw materials of the above-mentioned components are pulverized by the superfine pulverizer, and after passing through a 200-mesh sieve, they are mixed evenly according to the above-mentioned mass ratio to form a Chinese herbal medicine compound feed additive for sea cucumbers. The additive is added into the feed of sea cucumber, and the additive accounts for 0.5% of the total mass of the feed.

Abstract

The invention discloses feed additive for improving growth and immunity of Apostichopus japonicus. The feed additive for improving growth and immunity of Apostichopus japonicus is characterized by comprising, by weight, 0.1-0.3 part of chitosan oligosaccharide, 0.1-0.3 part of bacillus, 1-3 parts of astragalus root, 1-3 parts of licorice root, and 1-3 parts of radix angelicae sinensis. The feed additive is capable of improving growth and stress resistance of Apostichopus japonicus, reducing harm caused by stress and enhancing body immunity to increase survival rate of the Apostichopus japonicus. The compound feed additive mainly comprises the bacillus, the chitosan oligosaccharide, the manyprickle acanthopanax root, the astragalus root, fructus lycii, licorice root, lily bulb, the radix angelicae sinensis and root of bidentate achyranthis. The ingredients are made into the additive for common feed used to feed the Apostichopus japonicus according to a best proportion, and accordingly the Apostichopus japonicus grows well, weight gain is high, immuno-enzyme activity, and body immunity of the Apostichopus japonicus is improved. The feed additive has the advantages of no pollution, no residue, no side effects and the like.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive capable of improving the growth and immunity of sea cucumbers. Background technique [0002] sea ​​cucumber ( Apostichopus japonicus ) belongs to the phylum Echinodermata, the subphylum Wandering, the class Holothuria, the order Scutellaria, the family Apostichopae, and the genus Apostichopus. At present, sea cucumber has become a pillar industry of coastal characteristic agriculture and a support point for fishery economic growth. However, with the rapid development of high-density cultivation of sea cucumbers and the deteriorating water environment of sea cucumbers, diseases in cultivation also follow. At present, diseases have become an important factor limiting the sustainable and stable development of sea cucumber aquaculture. [0003] So far, epidemics caused by pathogenic organisms have caused significant economic losses in the farming industry. Viruses, bacteria, fun...
