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

Embodiment 1

[0048] Embodiment 1 raw material preparation

[0049] 1. Preparation of Yeast Culture

[0050] The preparation method of the yeast culture comprises the following steps: take the Saccharomyces cerevisiae tlj2016 slant strain after 1 ring activation, inoculate it into a 500mL Erlenmeyer flask containing 100mL seed medium, and cultivate it at 30°C with a shaker speed of 150r / h. Cultivate under the min condition for 28h to obtain the primary seed liquid; the primary seed liquid is inoculated into a 500mL Erlenmeyer flask containing 100mL fermentation medium at an inoculum size of 8% (v / v) for fermentation and cultivation, and the fermentation time is 28h. The temperature is 30°C, the rotating speed of the shaker is 180r / min, and the secondary seed liquid is obtained; the secondary seed liquid is inserted into a 5L fermenter with 3L fermentation medium for constant temperature fermentation with an 8% (v / v) inoculum, and the temperature is 30°C , the ventilation rate is 5L / min, th...

Embodiment 2

[0070] A high-yield catfish feed attractant is mainly prepared from the following raw materials in parts by weight:

[0071] 100 parts of compound flavor peptide, 10 parts of calcium fruit extract, 8 parts of wheat germ powder, 7 parts of betaine, 5 parts of tangerine peel powder, 9 parts of wormwood seed powder, 9 parts of yeast culture, 3 parts of seaweed powder, EM bacteria powder 1 copy;

[0072] The preparation method comprises the following steps: according to the formula, firstly, 25% of the quality of EM bacterial powder, yeast culture, wheat germ powder, compound flavor peptide, seaweed powder, wormwood seed powder, tangerine peel powder, betaine, and calcium fruit extract % Add in a V-shaped mixing tank and mix evenly for 15 minutes at a stirring speed of 30r / min, then add the remaining calcium fruit extract and mix evenly for 30 minutes at a stirring speed of 50r / min, aseptically fill, seal, and package to obtain a high-yield catfish feed attractant.

Embodiment 3

[0074] A high-yield catfish feed attractant is mainly prepared from the following raw materials in parts by weight:

[0075] 100 parts of compound flavor peptide, 8 parts of calcium fruit extract, 6 parts of wheat germ powder, 5 parts of betaine, 4 parts of tangerine peel powder, 7 parts of wormwood seed powder, 7 parts of yeast culture, 2 parts of seaweed powder, EM bacteria powder 0.5 copies;

[0076] The preparation method includes the following steps: according to the formula, firstly mix 20% of the quality of EM bacterial powder, yeast culture, wheat germ powder, compound flavor peptide, seaweed powder, wormwood seed powder, tangerine peel powder, betaine, and calcium fruit extract. % Add in a V-shaped mixing tank and mix evenly for 10 minutes at a stirring speed of 20r / min, then add the remaining calcium fruit extract and mix evenly for 20min at a stirring speed of 40r / min, aseptically fill, seal, and package to obtain a high-yield catfish feed attractant.

Abstract

The invention discloses a high-yield catfish feed attractant and a preparation method thereof and belongs to the technical field of feed additive preparation. The high-yield catfish feed attractant and the preparation method thereof have the advantages that the nutritional requirements of catfish and water environments are combined with the ingestion features of the catfish to optimize a raw material formula, raw materials are scientifically compounded to greatly increase palatability and feed utilization rate, and the attractant comprises compound flavor peptide which has high anti-oxidation effect and is capable of removing free radicals; the high-yield catfish feed attractant contains saccharomyces cerevisiae culture with functional features such as high nutrition, high bioactivity and high oxidation resistance, Prunus Humilis Bunge extract which can effectively supplement calcium, iron and soluble fibers, has a powerful embedding effect and can prolong shelf life, wormwood seed powder which can evidently increase an anti-freezing effect and stability, increase water resistance and glossiness, enhance and promote palatability and lower powder content, and wheat malt powder which can provide rich nutritional substances, bioactive substances, fragrant substances and plant enzyme sources; the prepared high-yield catfish feed attractant is high in palpability and good in production performance.

Description

technical field [0001] The invention relates to a feed additive, in particular to a high-yield catfish feed attractant 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 e...
