Embodiment 1

[0049] Embodiment 1 Raw material preparation

[0050] 1. Preparation of Yeast Culture

[0051] 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 invention discloses a palatable catfish feed compound enzyme and a preparation method thereof. Based on the nutritional requirements of catfish and the water body environment, combined with its digestive characteristics, the formula of raw materials is optimized, and the scientific compound has strong nutrition, biological activity and oxidation resistance. Saccharomyces cerevisiae cultures with functional characteristics; calcium fruit extracts that can effectively supplement calcium, iron and soluble fiber, have a strong encapsulation effect, and prolong the shelf life of feed compound enzymes; can significantly improve the antifreeze effect and stability of feed compound enzymes, improve Water resistance and luster of catfish feed, wormwood seed powder that can reduce feed powder content; palatability agent that can greatly improve feed palatability and digestibility; wheat malt powder that can provide rich nutrients, biologically active substances and plant enzyme sources; Finally, a palatable catfish feed compound enzyme that can significantly improve catfish digestibility and production performance, reduce feed coefficient, prevent water body pollution and maintain good water quality is provided.

Description

technical field [0001] The invention relates to a feed compound enzyme, in particular to a palatable catfish feed compound enzyme and a preparation method thereof. Background technique [0002] Catfish is an animal-eating fish and an excellent variety of freshwater fish. It is rich in nutrition. Every 100 grams of fish meat contains 64.1 grams of water, 14.4 grams of protein, and contains a variety of minerals and trace elements. It is especially suitable for the weak, weak, People who are malnourished eat it. Except that the catfish roe has a miscellaneous smell and is not suitable for consumption, the whole body is a treasure. Catfish is a rare and valuable nutritious product. It has been recorded in history books that it can be compared with shark's fin and wild soft-shelled turtle. It is a treasure among fish. Its therapeutic effect and medicinal value are not possessed by other fishes, and its unique characteristics of strengthening essence, strengthening bones and pro...
