Problems solved by technology

[0010] Although the catfish food attractants disclosed above are of various types, in various forms, and with complex ingredients, most of the taste raw materials have not been re-extracted and reprocessed, the waste of raw materials is serious, the amount of food attractants added is large, and the utilization rate of taste effective substances is low. The palatability, digestibility, feed-to-meat ratio, and disease resistance of catfish are still far from satisfactory

Abstract

The present invention discloses a silurus asotus feed phagostimulant and a preparation method thereof, and belongs to the technical field of feed additive preparations. Based on nutritional requirements of silurus asotus and water body environment, and combining food intake characteristics, a formula of raw materials is optimized. The silurus asotus feed phagostimulant scientifically combines compound flavor peptides greatly improving palatability and feed utilization rate, having a relatively strong anti-oxidation effect and eliminating free radicals; an accharomyces cerevisiae culture having functional characteristics of being strong in nutrition, biological activity, oxidation resistance, etc.; a high-calcium cerasus humilis extract effectively supplementing calcium, iron and soluble fibers, having a strong embedding effect and prolonging a shelf life; artemisia carvifolia seed powder significantly improving antifreeze effects and stability, improving water resistance and gloss, and enhancing and promoting palatability; and wheat malt powder providing rich nutrients, bioactive substances and plant enzyme sources. Finally, the prepared silurus asotus feed phagostimulant is strong in phagostimulant and good in production performances.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed attractant for catfish and a preparation method thereof. Background technique [0002] The feeding behavior of fish is the same as that of other animal groups. It has to go through a series of food quality evaluation processes such as searching, locating, accepting, and obtaining, and then through processes such as swallowing, digestion, absorption, and assimilation, which are directly related to energy requirements. It determines the survival and extrusion of fish growth, maturity and spawning. The feeding behavior of fish involves many sensory systems, but two major sensory systems play a major role: the olfactory system and the gustatory system. Behavior can be divided into two stages: 1) The olfactory system perceives the direction and position of food, and approaches it after becoming interested; 2) The taste system evaluates the taste of food and finally decides whether to eat. In ...
