Embodiment 1

[0026] Formula of fish feed attractant containing glycosyl isopropyl sulfide: in parts by weight, 15 parts of glycosyl isopropyl sulfide, 15 parts of oxaloacetic acid, 20 parts of worm powder, 18 parts of leek seed extract , 10 parts of nucleotides, 3 parts of choline chloride, 3 parts of astaxanthin, and 5 parts of perilla seed oil.

[0027] Preparation:

[0028] 1) Pulverize the raw materials of the food attractant, mix them according to the principle of superimposing a small amount, pass through a 200-mesh sieve, and mix them with a mixer for 10 minutes to obtain a mixed food attractant;

[0029] 2) Take 2 kg of the mixed food attractant prepared in step 1) and add it to a wet granulator, add 10% water, and wet granulate, wherein the mixing and cutting speeds are respectively 400r / min and 3500r / min;

[0030] 3) Place the food-attractant granules prepared in step 2) in a fluidized bed, dry them, and dissolve a mixture of 60 g of sodium hyaluronate and peach gum in hot water...

Embodiment 2

[0032] The glycosyl isopropyl sulfide-containing fish feed attractant prepared in Example 1 is used as a test group, the feed attractant is not added as a control group, and grass carp is used as a test fish, and the initial average body weight is (79.89 ± 0.85) g, the experiment was randomly divided into 2 groups, each group had two parallels, and each parallel selected 20 healthy fish with no wounds on the outside, a total of 80 fishes, the two groups were fed with the same feed, and the experimental group was fed with 5% of the added amount Add food attractant, the control group does not add food attractant, and the feeding period is 10 weeks.

Abstract

The invention discloses a fish feed attractant containing glycosyl isopropyl sulfide. On the basis of weight of the attractant, the attractant comprises 0.01%-50% of glycosyl isopropyl sulfide, 0.01%-50% of oxaloacetic acid or salt thereof, tylorrhynchus powder and compound amino acid. The fish feed attractant has the benefits as follows: glycosyl isopropyl sulfide, oxaloacetic acid and cured tylorrhynchus powder are used as main components of the freshwater aquaculture fish feed attractant and have a synergistic effect with properly added Chinese chive seed extract, nucleotide, alkaloid, astaxanthin and purple perilla seed oil, so that the attractant has strong irritation effect on gestation and smell of fish, has excellent attraction effect and can active activity of digestive enzyme, promote digestion and absorption and improve the oxidation resistance of organisms so as to effectively increase intake of fish, improve feed efficiency, promote fish growth and reduce pollution of culture water.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing, in particular to a fish feed attractant containing glycosyl isopropyl sulfide. Background technique [0002] Aquatic animal feed attractant is a non-nutritional additive, which is artificially synthesized or extracted according to the chemical components contained in the animals and plants that aquatic animals are most fond of. The attractant is often composed of two or more compounds. These compounds have a synergistic effect on the feeding of aquatic animals. By stimulating the senses of smell, taste and vision of aquatic animals, they gather around the feed, speed up food intake, and increase feed intake. [0003] Due to the pollution of marine resources, the resources of fishmeal and fish oil are in short supply and the prices are rising all the way. In my country's freshwater intensive aquaculture, people continue to develop new protein sources to replace fish meal, and use ...
