[0002] At present, in the process of aquaculture, the diseases that occur during the growth of aquatic products are mostly treated by means of drug control or adding chemical additives to the feed. Bacteria often develop drug resistance due to improper use of drugs or blind use of chemical additives. Drug residues in aquatic products will eventually affect the food safety of aquatic products

Embodiment 1

[0006] Example 1: The ingredients in the additive are mixed according to the mass ratio: 20 grams of bioactive peptide, 10 grams of medical stone, 10 grams of defatted rice bran, and 20 grams of seaweed powder, a total of 60 grams. All components must be ultrafinely ground to 150 meshes, and after being fully mixed, they can be fed into sea cucumber overwintering seedling ponds or mixed with 20% of the feed. After 60 days of indoor factory feeding experiments on sea cucumbers, the results showed that the weight gain rate of the experimental group increased by 7.2%, the activity of superoxide dismutase increased by 3.4%, and the activity of alkaline phosphatase increased by 8.4% compared with the control group (without adding additives). .

Embodiment 2

[0007] Example 2: The ingredients in the additive are compounded according to the mass ratio: 60 grams of bioactive peptide, 40 grams of medical stone, 50 grams of defatted rice bran, and 50 grams of seaweed powder, totaling 200 grams. All components must be ultrafinely ground to 200 meshes, and after being fully mixed, they can be fed to sea cucumber overwintering seedling ponds or mixed with 20% of the feed. After 60 days of indoor factory feeding experiments on sea cucumbers, the results showed that the weight gain rate of the experimental group increased by 14.6%, the activity of superoxide dismutase increased by 3.8%, and the activity of alkaline phosphatase increased by 9.1% compared with the control group (without adding additives). .

Embodiment 3

[0008] Example 3: The ingredients in the additive are compounded according to the mass ratio: 40 grams of bioactive peptide, 25 grams of medical stone, 30 grams of defatted rice bran, and 35 grams of seaweed powder, a total of 130 grams. All components must be ultra-finely ground to 170 meshes, and after being fully mixed, they can be fed to sea cucumber overwintering seedling ponds or mixed with 20% of the feed. After 60 days of indoor factory feeding experiments on sea cucumbers, the results showed that the weight gain rate of the experimental group increased by 18.8%, the activity of superoxide dismutase increased by 3.5%, and the activity of alkaline phosphatase increased by 9.6% compared with the control group (without adding additives). .

Abstract

The invention discloses an additive of polypeptide feed for sea cucumbers, which is characterized by comprising the following components in the mass ratio that bioactive peptide: medical stone: defatted rice bran: seawood meal is 20-60: 10-40: 10-50: 20-50, wherein the number of meshes of each crushed component is 150-200. The additive of polypeptide feed for sea cucumbers is added into feed in a certain proportion, sea cucumbers have independent digestion and absorption run modes in vivo, after eaten by sea cucumbers, the additive can promote the ingestion and the digestion, improve the digestion and metabolism functions, enhance the immune and promote the growth of the sea cucumbers, is a safe and non-toxic green feed additive without residuals, and can improve the weight increment rate by 7.2-18.8 percent.

Description

technical field [0001] The invention relates to an additive, in particular to a sea cucumber polypeptide feed additive. Background technique [0002] At present, in the process of aquaculture, the diseases that occur during the growth of aquatic products are mostly treated with drugs or by adding chemical additives to the feed. Bacteria often develop drug resistance due to improper use of drugs or blind use of chemical additives. Drug residues in aquatic products will eventually affect the food safety of aquatic products. Sea cucumber, as a sea treasure, meets the needs of the public for supplementing medicine and food and improves people's quality of life. At the same time, it also faces food safety problems. Therefore, in order to ensure the edible safety of sea cucumber, a new sea cucumber feed additive, to improve For sea cucumber's own disease resistance, it is very necessary to eliminate the use of drugs and chemical additives. Contents of the invention [0003] Th...
