Abstract

The invention discloses a catfish feed complex enzyme containing a yeast culture and a preparation method thereof. The complex enzyme is characterized in that on the basis of catfish nutrient requirements and water body environment, and the digestion characteristics of catfish, the formula of raw materials is optimized, a wine-brewing yeast culture, a prunus humilis bunge extract, wormwood seed powder, a palatable agent and wheat malt powder are scientifically compounded, wherein the wine-brewing yeast culture has function characteristics of strong nutrient property, biological activity, anti-oxidizing property and the like; the prunus humilis bunge extract can effectively supplement the calcium, iron and soluble fiber, has strong encapsulating function, and can extend the quality warranty period of the feed complex enzyme; the wormwood seed powder can obviously improve the anti-freezing effect and stability of the feed complex enzyme, improve the water-resistant property and luster of the catfish feed, and reduce the powder content in the feed; the palatable agent can greatly improve the palatability and digestion rate of the feed; the wheat malt powder can provide rich nutrient substances, biological active substances and plant enzyme sources. The complex enzyme of the catfish feed containing the yeast culture has the advantages that the digestion rate and yield rate of the catfish are obviously increased, the feed coefficient is reduced, the pollution to a water body is decreased, and the high water quality is maintained.

Description

technical field [0001] The invention relates to a feed compound enzyme, in particular to a catfish feed compound enzyme containing yeast culture 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, strengthenin...
