Biological fermentation protein feed and preparation method thereof

Abstract

The invention discloses a biological fermentation protein feed and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a fermentation substrate; (2) preparing a fermentation agent; (3) fermenting, i.e., preparing the protein feed through a biological fermentation technology; (4) drying. According to the method, waste edible fungi waste and animal blood can be fully used; through the biological fermentation technology, multiple strains are combined to produce the protein feed; through the method, the edible fungi waste and the animal blood can be recycled; the resource is saved, the environment pollution is reduced, and the environment protection is facilitated; the prepared protein feed is low in cost, high in nutrition and excellent in palatability, has natural fermentation fragrance and an excellent attractant effect, and can prompt young animals for ingestion.

Description

technical field [0001] The invention belongs to the field of biotechnology fermentation engineering, and in particular relates to a biologically fermented protein feed and its preparation method, in particular to the production of edible fungus waste, livestock and poultry blood and plant cake by adding various microorganisms and bioengineering enzymes through fermentation technology. A new type of protein feed. Background technique [0002] Due to the continuous growth of population, the frequent occurrence of food safety problems, the contradiction between the supply and demand of healthy food has become increasingly prominent, especially the protein resources per capita in my country is much lower than the world average level, and the market price of protein feed raw materials such as soybean meal and fish meal is getting higher and higher. It goes up every year. [0003] With the rapid development of science and technology, people continue to pursue high-quality life, an...

Problems solved by technology

Most of the large-scale livestock and poultry slaughtering plants only use the slaughtered blood in the natural sun, and the blood is processed by a high-temperature drying process at about 100 degrees, and the natural drying method of animal blood is easy to cause pollution. At the same time, drying animal blood When the temperature exceeds 60 degrees, its bioavailability will be reduced. In addition, the blood has a fishy smell, and the palatability of high-temperature drying products is relatively poor.
