Abstract

The invention provides a preparation method of myriophyllum elatinoides functional feed. The preparation method comprises the following steps: 1) cutting raw materials; (2) inoculating and mixing; (3) bagging and sealing; 4) performing constant-temperature fermentation; 5) drying to prepare powder; and 6) mixing viable bacteria. The prepared myriophyllum elatinoides functional feed is fermented by adopting lactobacillus plantarum, so that the protein content, fat content and ash content in the myriophyllum elatinoides are increased, and the cellulose content in the myriophyllum elatinoides is reduced. According to the feed, the nutritional value and palatability of the myriophyllum elatinoides feed are improved, and the feed is convenient to store and transport; the intestinal flora structure of animals is improved, the production of beneficial metabolites is promoted, and 10%-20% of conventional feed can be replaced; meanwhile, the problem that secondary pollution is easily caused after the culture wastewater is treated by the myriophyllum verticillatum is solved, and mutual unification of environmental protection and resource development and utilization is realized.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and relates to a functional feed for viridiflora and a preparation method thereof. Background technique [0002] In recent years, the global food crisis has intensified, and the international food price has risen rapidly. my country's feed grain accounts for 1 / 3 of the total grain output, and 40.0% of the cultivated land is used for feed production. With the rapid development of my country's animal husbandry industry, protein and energy feed resources are in short supply, and the cost of breeding is too high. The shortage of feed resources has always affected the sustainable development of animal husbandry and has become a major challenge for my country's animal husbandry. The development and utilization of grain and feed is an urgent problem to be solved in the current aquaculture development. [0003] At the same time, with the vigorous development of my country's aquaculture industry, ...
