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...

Abstract

The present invention discloses a functional feed attractant for catfish and a preparation method thereof, and belongs to the technical field of preparation of feed additives. Based on nutrient demands of the catfish and the water body environment, through combining feeding characteristics, and optimizing a raw material formula, compound flavor peptides capable of greatly improving the palatability and feed utilization rate, having a relative strong anti-oxidation effect and scavenging free radicals, a saccharomyces cerevisiae culture with function characteristics such as strong nutritional, bio-active and anti-oxidation properties, a cerasus humilis fruit extract capable of effectively supplementing calcium, iron and soluble fibers, and having a strong embedding effect and prolonged shelflife, wormwood seed powder capable of significantly improving an antifreeze effect and stability, improving water resistance and glossiness, enhancing and promoting palatability, and reducing powder-containing rate, and wheat malt powder rich in nutrients, biological active substances, aroma substances and plant enzyme sources are scientific compounded; and finally the functional feed attractantfor the catfish which is strong in palatability and good in production performance is prepared.

Description

technical field [0001] The invention relates to a feed additive, in particular to a functional 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...
