Problems solved by technology

[0003] However, the traditional feed does not pay much attention to the species of animals, the microbial flora of the digestive tract and the characteristics of physiological digestion. The feed can only provide basic nutrients and hormones, mainly to ensure the growth rate and output of animals, but for the Intestinal function and immune function are not involved too much, and cannot be well adapted to different breeding species, such as pigs, poultry, cattle, and aquatic animals, which indirectly leads to an increase in the mortality of animals and reduces their economic value

Abstract

The present invention discloses an animal feed yeast body protein and a preparation method thereof; the animal feed yeast body protein comprises candida utilis, candida tropicalis, torulopsis torulopsis, saccharomyces cerevisiae, a mixed additive, and water added to 1g as a supporter; wherein in more than 1800 strains of the three types of strains, a strain biochemical experiment and a strain symbiosis experiment are carried out, thereby selecting the microorganisms and preparing a yeast suspension. According to the present invention, the variety, the digestive tract microflora and the physiological digestion characteristics of animals are fully paid attention to, and the rich functional factors can improve the gastrointestinal function and the immune function of the animals, so that the animal feed yeast body protein is rich in B vitamins, organic trace elements, enzymes, small peptides, organic acids and other various yeast metabolites. The product can improve the digestion utilization rate of the feed, improve the production performance and reduce the production cost. Therefore, the feed digestion and utilization rate is increased, the disease resistance of the organism is enhanced, and the mycoprotein is high-quality mycoprotein which is very suitable for pigs, poultry, cattle and aquatic animals.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to an animal feed yeast cell protein and a preparation method thereof. Background technique [0002] Yeast cell protein, also called microbial protein, is a microbial cell artificially cultivated with many industrial and agricultural wastes and petroleum wastes. Therefore, single-cell protein is not a pure protein, but is composed of protein, fat, carbohydrates, nucleic acid and The cytoplasmic mass composed of nitrogen-containing compounds, vitamins and inorganic compounds that are not proteins, and the mutual matching of mixed feeds can improve the nutritional value and multi-functionality of feeds, which is the main development direction of modern scientific feeds. [0003] However, the traditional feed does not pay much attention to the species of animals, the microbial flora of the digestive tract and the characteristics of physiological digestion. The feed can only provide...
