Embodiment 1

[0021] A preparation method of a fish feed additive, said method comprising the steps of:

[0022] A. After pulverizing demosmectite and humic acid, mix them in a ratio of 3.5:1, add 5% yeast fermentation broth and 10% Bacillus fermentation broth, stir evenly, adjust the pH value to 8.5, shake for 10 hours, and then After natural air-drying at room temperature for 3 days, the composite was pulverized and set aside;

[0023] B. Weigh 2 parts of pine needle powder, 0.3 part of cellulase, 1 part of methionine, 0.5 part of premix and 1 part of the complex prepared in step A, mix them, and stir evenly to obtain the fish feed additive. In order to implement the present invention better, the usage amount of the additive of the present embodiment is 2.3%.

Embodiment 2

[0025] A preparation method of a fish feed additive, said method comprising the steps of:

[0026] A. After pulverizing demosmectite and humic acid, mix them in a ratio of 4.2:1, add 6% yeast fermentation broth and 12% Bacillus fermentation broth, stir evenly, adjust the pH value to 8.7, shake for 12 hours, and then After natural air-drying at room temperature for 4 days, the composite was pulverized and set aside;

[0027] B. Weigh 4 parts of pine needle powder, 0.5 part of cellulase, 1.2 part of methionine, 0.8 part of premix and 2 parts of the complex prepared in step A, mix them, and stir evenly to obtain the fish feed additive. In order to implement the present invention better, the practical amount of the additive of the present embodiment is 2.5%.

Embodiment 3

[0029] A preparation method of a fish feed additive, said method comprising the steps of:

[0030] A. After pulverizing demosmectite and humic acid, mix them in a ratio of 5:1, add 8% yeast fermentation broth and 15% Bacillus fermentation broth, stir evenly, adjust the pH value to 9, shake for 15 hours, and then After natural air-drying at room temperature for 5 days, the composite was pulverized and set aside;

[0031] B. Weigh 5 parts of pine needle powder, 0.6 part of cellulase, 1.5 parts of methionine, 1 part of premix and 3 parts of the complex prepared in step A, mix them, and stir evenly to obtain the fish feed additive. In order to implement the present invention better, the practical amount of the additive of the present embodiment is 3%.

Abstract

The present invention provides a fish feed additive preparation method. Montmorillonite and humic acid are added to yeast fermentation broth and bacillus fermentation broth, the pH value of the fermentation broth is adjusted to be 8.5-9, then the fermentation broth is oscillated for 10-15 h, air-dried, and smashed to obtain a complex body, and then the complex body is mixed with other raw materials evenly to obtain the fish feed additives. The fish feed additives obtained by this method can effectively absorb and decompose various types of mycotoxins of the feed raw materials, and solve the problems of serious mycotoxin contamination of domestic feeds. By using the prepared fish feed additives, the mycotoxin removing effect of the feed is ensured, and also the nutrient balance of the feed is improved, and the utilization of the feed is not affected.

Description

technical field [0001] The invention relates to the technical field of feed additives for aquaculture, in particular to a preparation method of a fish feed additive. Background technique [0002] With the continuous development of the feed industry and animal husbandry, high-quality pellet feed is becoming more and more popular in the market, especially in the aquaculture industry, the demand for high-quality, high-paying aquatic feed is also rising, feed processing enterprises It will also improve the quality of feed as a constant pursuit of the goal. Pellet feed has a series of advantages such as comprehensive nutrition, good palatability, shortening feeding time, avoiding picky eaters, convenient transportation, storage, and mechanization of feeding, and its proportion in the total feed is constantly increasing. However, mold contamination of feed is a global problem. China is the hardest hit country for mycotoxins. The reason is that the equipment conditions in the...
