Problems solved by technology

This process can improve the material conditioning environment, and can also reduce the compression ratio of the ring die of the granulator in the subsequent granulation process. However, in actual processing, the raw materials of the feed are easily deposited in the water body after processing, resulting in an increase in the nutrient content of the water body. Then it is easy to cause the resistance of tilapia to decline, and the consumption of raw materials is high, and the palatability is insufficient, which affects the feeding effect of tilapia feed

Abstract

The invention belongs to the technical field of feed, and discloses a preparation method and application of environment-friendly tilapia feed, the preparation method comprises the following steps: inoculating probiotics to a slant culture medium for culture to obtain slant bacterial liquid, then inoculating the slant bacterial liquid to a liquid culture medium for anaerobic culture to obtain source bacterial liquid; inoculating the source bacterial liquid into a fermentation culture medium, and performing cultivation and symbiosis to obtain a strain infiltrating liquid; adding corn, bran, wheat flour, rapeseed dregs, distillers' grains, soybean meal and dried small shrimps into the strain infiltration liquid, mixing and stirring, and fermenting to obtain a fermented material; and granulating the fermented material, and spraying the coating liquid to obtain the tilapia mossambica feed. The vinasse, the rapeseed meal and the soybean meal are added into the raw materials and can be matched with fermentation of the zymophyte liquid to take out self fibers, crude protein nutrition in the raw materials is supplemented, meanwhile, addition of the raw materials such as bran and corn is reduced, and metabolic activity of microorganisms is fully utilized, so that the nutritional value of the raw materials is increased. The purpose of decomposing and converting anti-nutrient substances in the fermentation raw materials is achieved.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a preparation method and application of an environment-friendly tilapia feed. Background technique [0002] Fermented feed technology uses the metabolic activities of microorganisms to achieve the purpose of decomposing and transforming anti-nutritional substances in feed through artificial control. Fermentation can effectively remove anti-nutritional factors in the feed, such as trypsin inhibitors, glycinin, etc., and at the same time, the content of biologically active substances such as probiotics, proteases and small molecular peptides is significantly increased, which greatly improves the nutritional value of the feed. protein and macromolecule starch. [0003] The related technology discloses a production process of tilapia pellet feed. The production process includes: the raw materials of tilapia feed are subjected to a first conditioning treatment by a first conditioner, an...
