Problems solved by technology

While the compound amino acid is close to the control group, some indicators are still lower than the control group, and the effect is poor.
In the prior art, the research on food attractants for hybrid snakeheads is still relatively weak, especially the lack of special food attractants for hybrid snakeheads with significant effects and complete nutrition

Embodiment 1

[0031] Mix 30% astragalus, 20% cinnamon, 20% peppermint, 20% forsythia and 10% flavescens by weight, ultrafinely pulverize and pass through a 200-mesh sieve to obtain a mixture, add water (the mass ratio of raw materials to water is 1:12) After stirring, go through a colloid mill to mix and homogenize 3 times, and extract with hot water at 100 degrees for 4 hours. Filter the residue to obtain the primary extract of Chinese herbal medicine, and concentrate to 1 / 10. Add 95% ethanol (mass ratio of raw material: ethanol = 1:10) to precipitate the active ingredient. The obtained precipitate is spray-dried, the rotational speed of the nozzle is 15000-18000 revolutions per minute, the temperature of the air inlet is 200-220 degrees, the temperature of the air outlet is 90-100 degrees, and the negative pressure is 100 mpa to obtain the Chinese medicine extract.

Abstract

The present invention belongs to the field of aquatic feed additive technology, and it has disclosed a special seductive agent and preparation method of hybrids.With the quality of dry substance quality, the seductive agent includes the following components: 15 ~ 30%of the composite Chinese herbal medicine extract, 34 ~ 51%composite amino acids, 15 ~ 20%of sulfur -containing compounds, 10%to 20%of alkaloids, nucleoside, and nucleoside9 ~ 24%; the raw materials of the composite Chinese herbal medicine extracts are astragalus, cinnamon, mint, forsythia and cinnamon.The present invention found through a large number of creative experiments: composite Chinese medicine extracts, composite Chinese medicine extracts of astragalus, cinnamon, mint, forsythia, and cinnamin with conventional use of composite amino acids, sulfur -containing compounds, alkaloids and nucleotides in specific formulas, can be used to start, which can be started.To the role of coordinated efficiency, it can significantly improve the seductive effect of hybrids.

Description

technical field [0001] The invention relates to the technical field of aquatic feed additives, in particular to a special food attractant for hybrid snakeheads (Channamaculatus (♀) C. argus (♂)) and a preparation method thereof. Background technique [0002] Channa argus (Channa argus) and Channa maculata (Channa maculata) are important native fishes in my country, belonging to the order Perciformes, the suborder Anabantoidei, the family Channidae, and the genus Channa. The hybrid snakehead is the offspring of interspecific hybridization obtained by the distant hybridization of the black snakehead and the spotted snakehead. It has obvious distant hybridization advantages such as fast growth and low feed ratio. The total output of hybrid snakeheads in the country has steadily increased from 180,000 tons in 2003 to 450,000 tons in 2013, and a complete industrial chain has been formed from seed production, breeding, feed processing to transportation and sales. The demand for h...
