Active dry yeast for increasing utilization rate of feed and preparation method of active dry yeast

Abstract

The invention discloses active dry yeast for increasing the utilization rate of a feed and a preparation method of the active dry yeast. The active dry yeast comprises the following raw materials in parts by weight: 40-60 parts of rice bean powder, 22-29 parts of flour, 2-6 parts of horseradish tree leaf powder, 5-9 parts of mashed green peppers, 1-1.5 parts of mucor seed liquid, 0.3-0.6 part of mashed sweet potatoes, 0.1-0.2 part of waste molasses, 0.2-0.4 part of milk powder, 0.1-0.3 part of microzyme seed liquid, 2-3 parts of steam fish meal, 1-2 parts of a duck meat extract, 1-2 parts of gordon euryale seed powder, 3-4 parts of carrageenin, 0.5-1 part of fermented soya bean powder and 1-2 parts of chicken bone oil. According to the active dry yeast and the preparation method thereof ,disclosed by the invention, the activity and the stability of the active dry yeast are improved, the pollution of sundry bacteria is avoided, the shelf life is prolonged, the palatability of the dry yeast is improved, the food consumption of animals is increased, the gastrointestinal tract health of the animals is improved, the growth and the development of the animals are promoted, the utilization rate of the feed is increased, the material consumption quantity is reduced, the breeding cost is reduced, and the breeding benefits are improved.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to an active dry yeast for improving feed utilization and a preparation method thereof. Background technique [0002] The safety of feed additives has always been a hot spot of concern. Since antibiotics have been used as feed additives, they have been controversial. On the one hand, they can reduce certain diseases of animals and improve their production performance; Ecological balance induces cross-infection of pathogenic bacteria. Under such circumstances, a new class of feed additives without drug resistance and residues——microecological feed additives emerged as the times require, and more and more attention has been paid to them. Active dry yeast is a kind of micro-ecological feed additive. It is a kind of probiotics. It plays a role in the secretion of protease and other digestive enzymes in the intestinal tract of animals, participates in biological oxygen consumpt...

AI Technical Summary

Problems solved by technology

In the past, due to the limitation of processing technology, when making feed additives, the processing level of active dry yeast was not high, the palatability was also poor, and the utilization rate of nutrients was not high.
