Problems solved by technology

[0004] Hybrid mulberry is rich in nutrients, but the molecular weight of hybrid mulberry protein is large, and the digestion and absorption rate of direct feeding animals is low; hybrid mulberry contains high content of anti-nutritional factors such as tannin, which not only affects the health of animals, but also increases the bitterness of the feed Sensation, reduce animal feed intake; in industrial production, the branches of the tree are combined with mechanized harvesting, and the crude fiber content is high

Embodiment 1

[0031] An ecological grass carp feed added with fermented hybrid mulberry powder, which is made of the following raw materials in mass percentage: 25% fermented hybrid mulberry powder, 20% soybean meal, 20% rapeseed meal, 10% wheat flour, 6.7% rice bran, and 13% malt root %, soybean oil 2%, calcium dihydrogen phosphate 2%, choline 0.3%, grass carp premix 1%.

[0032] The grass carp premix was purchased from Gaoxin Feed Co., Ltd., Gaoyao City, Guangdong Province.

[0033] The fermented hybrid tree powder is made by the following steps: when the stem height of the hybrid tree is 1-1.2m, the stems are cut down at the end leaves, the fresh leaves and stems are pulverized by a refiner, and the The leaves and stems of the mulberry tree are ground into the size of rice grains, inoculated with microorganisms into the mulberry tree powder, and carbon sources and inorganic salts are added, packed and compacted, stored in sealed plastic film bags, and fermented at room temperature for 3 ...

Embodiment 2

[0040] Experimental Design: The experiment was divided into two groups, the experimental group and the control group. The experimental group: fed the fermented hybrid mulberry ecological grass carp feed in Example 1; the control group: fed a certain brand of "grass carp compound feed" sold on the market. There were 4 replicates in each group, 50 fish in each replicate, and a total of 200 fish in each group.

[0041] Test material: fermented hybrid tree ecological grass carp feed in embodiment 1;

[0042] Experimental animals: Grass carp (about 700 grams in weight), provided by Jinfeng Aquaculture Farm, Yanghe Town, Gaoming District, Foshan City (a total of 400 fish are required).

[0043]Test location: Aquaculture farm of Fengxin Biotechnology Technology Co., Ltd., Shunde District, Foshan City. A total of 2 (×4) pond cages are required.

Abstract

The invention discloses a grass carp feed containing fermented hybrid paper mulberry powder and an application thereof. The grass carp feed contains 20-30% of fermented paper mulberry powder; the fermented paper mulberry powder is prepared by the following steps: when the stalk of the paper mulberry grows to 1-1.2m high, cutting the stalk from the last leaf; grinding fresh paper mulberry leaves and stalk; polishing the paper mulberry leaves and stalk into rice grain size; inoculating the paper mulberry powder with microorganisms and adding a carbon source and inorganic salt; carrying out sub-packaging, compacting and storing in a sealed plastic film bag; and carrying out fermentation and culture for 5-8 days at room temperature. The paper mulberry is preferentially hybrid paper mulberry. In the grass carp feed disclosed by the invention, the fermented hybrid paper mulberry powder contained has the advantages of great nutritional value, high digestibility and obvious growth promoting effect; in the fermented paper mulberry powder, active functional components are increased, few toxic and side effects are caused, and a large quantity of beneficial bacteria are generated to realize the effects of improving the fish flavor and raising the health level of the grass crap body; and the sour fragrance after fermentation effectively improves the feed attraction.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a grass carp feed, in particular to a grass carp feed containing fermented hybrid tree powder and its application. Background technique [0002] Grass carp, also known as grass carp, grass carp, etc., belongs to the genus Grass Carp of Cyprinidae Cyprinidae and is a typical herbivorous fish. It is the most important large-scale freshwater fish in my country, with an annual output of several million tons. . Grass carp farming consumes millions of tons of feed grain every year. Finding new feed sources that can replace food crops, especially high-protein, functional feed ingredients, has become the key to the sustainable development of livestock and poultry aquaculture. And as aquaculture has entered the modern high-density intensive farming mode in recent years, excessive pursuit of breeding speed and feed remuneration has led to frequent occurrence of fish diseases, reduce...
