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.
