Embodiment 1

[0030] Food attractant and its preparation

[0031] The present invention uses cottonseed meal enzymatically hydrolyzed peptide as the main component, and then is supplemented with 5'-guanylate disodium, antioxidant, antifungal agent, and zeolite powder to prepare a uniform phagostimulant.

[0032] The preparation process of cottonseed meal enzymatic peptide is as follows:

[0033] 1) The cotton meal is crushed by a pulverizer and passed through a 100-mesh sieve. The sieved raw materials are stirred and mixed. Weigh 40g of the sieved raw materials into a beaker, add distilled water, and stir fully under a magnetic stirrer;

[0034] 2) Adjust the pH to 7.0 with 1mol / L NaOH solution, and accurately weigh the subtilisin (add at 2500IU / g protein, where the protein is the protein content in the cotton meal, and determine the protein content in the cotton meal before preparation ), distilled water to 1L;

[0035] 3) Divide the solution evenly into 4 500ml conical flasks, shake the water bath...

Embodiment 2

[0039] A food attractant for Chinese mitten crabs, which is composed of the following raw materials in parts by weight: 68 parts of cottonseed meal enzymatic peptide, 5'- guanylic acid disodium 5 parts, antioxidant 2 parts, and anti-mold agent 3 Parts, 2 parts of zeolite powder.

Embodiment 3

[0041] A food attractant for Chinese mitten crabs, which is composed of the following raw materials in parts by weight: 65 parts of cottonseed meal enzymatic peptide, 6 parts of 5'-guanylate disodium, 2 parts of antioxidants, 3 parts of antifungal agent Parts, 2 parts of zeolite powder.

Abstract

The invention discloses a phagostimulant for Eriocheir sinensis and a preparation method and application of the phagostimulant. The phagostimulant comprises, by weight, 60-70 parts of cottonseed mealenzymatic hydrolysis peptide, 3-6 parts of 5'-disodium guanylate, 1-3 parts of antioxidant, 3-5 parts of mildew preventive and 1-3 parts of zeolite powder. The invention further relates to Eriocheir sinensis feed containing the phagostimulant, and the adding quantity of the phagostimulant in the compound feed is 0.2-0.8%. The phagostimulant has the advantages that the phagostimulant is prepared according to the ingestion habits of the Eriocheir sinensis, the appetite of the Eriocheir sinensis can be simulated when the phagostimulant is used, the slow ingestion problem of the Eriocheir sinensisis solved effectively, the ingestion speed and quantity of the Eriocheir sinensis are increased, feed utilization rate is increased favorably, and digestion is promoted.

Description

Technical field [0001] The invention belongs to the technical field of aquatic animal additives, and relates to a food attractant for Chinese mitten crabs and a preparation method and application thereof. Background technique [0002] Chinese mitten crab (Eriocher sinensis) is an important economically cultivated crab in my country, and its output is increasing year by year. According to statistics from the Food and Agriculture Organization of the United Nations, the output of Chinese mitten crabs in 2016 has reached 812,103 tons. Chilled fish used to be the main source of bait in crab breeding. However, with the development of the Chinese mitten crab breeding industry, traditional natural baits such as chilled fish have been unable to meet their breeding needs due to declining resources, imbalanced nutrients, environmental pollution, and carrying pathogens. Therefore, the development and application of artificial compound feed in the breeding process has gradually been accepte...
