Embodiment 1
[0012] A food attractant for raw fish feed comprises dimethyl-beta-thiatin propionate, glycine, alanine, betaine, taurine and fillers, wherein the weight percentage of each component is as follows:
[0014] Wherein, the filler is flour or rice bran or the like.
[0015] The food attractant was evaluated through an 8-week growth feeding experiment. The specific method was to add 2% squid extract (D), 0.1% (A) and 0.2% (B) compound attractants to raw fish commercial feed respectively. Food preparations, three kinds of experimental feeds were made, and the raw fish whose initial body weight was 73.9±1.44g were raised for 8 weeks.
[0016] The results are shown in Table 1; show that the weight gain rate and food intake rate of raw fish fed with different feeds are in order: B>A>D, wherein the weight gain rate and food intake rate of raw fish in group B are significant...

Abstract
The invention relates to a phagostimulant for a raw fish feed. The phagostimulant comprises the following components by weight percent: 10-15% of dimethyl-beta-thetin propionate, 5-10% of glycine, 5-10% of alanine, 40-50% of betaine, 5-10% of taurine and 10-30% of fillers, wherein the fillers are flour or rice bran and the like. Various single phagostimulants are compounded into the phagostimulant for the raw fish feed; the food-calling effect to the raw fish is good; the phagostimulant is added into the fish feed, so that nutritional ingredients required by the growth of the fish are supplied by the amino acid contained in the phagostimulant, the safety is high and the environmental protection is boosted; the adding amount is small; the production cost is low; the adopted raw materials are stable in quality and conveniently purchased; and the phagostimulant is easily popularized.
Description
technical field [0001] The invention relates to a feed additive, in particular to a feed attractant for fish feed. Background technique [0002] The food attractant of fish feed used to use the extracts of bovine liver, water earthworm and viscera, and used the amino acids in the raw materials to attract food, but this method added a large amount, and it was not easy to process the feed, and the quality could not be guaranteed. , There is also the purpose of attracting food by adding squid paste to fish feed. Due to the lack of squid resources, the quality of commercially available squid paste is unstable, and the cadmium content is high, which poses a safety hazard to the breeding of raw fish. [0003] At present, many food attractants have been found, such as DMPT (dimethyl-β-thiatin propionate), alkaloids, amino acids and nucleotides, among which DMPT is the most effective aquatic food attractant found so far. Food agent, through the olfactory sense of aquatic animals, c...
