Highly efficient oligosaccharide high yielded enzyme composite animal microecological formulation without public hazard and its preparing method

Abstract

The composite microecological animal preparation consists of Bacillus cereus 10-15 wt%, Bacillus subtilis 10-15 wt%, Bacillus licheniformis 10-15 wt%, Saccharomyces cerevisiae 1-5 wt%, Candida Tropicalis 1-5 wt%, photosynthetic bacterium 1-5 wt%, plant lactobacillus 0.5-3 wt%, acidophilic lactobacillus 0.5-3 wt%, ephebic bifidobacterium 1-3 wt%, Aspergillus niger 0.5-3 wt%, Aspergillus oryzae 0.5-3 wt%, viridin 0.5-3 wt%, oligosaccharide 5-10 wt% and carrier 30-50 wt%. Its preparation process includes the following steps: 1) high temperature resisting domestication of the said strain, drug resisting domestication, preservation and strain passage; 2) activating the preserved strain, fermentation, coating with microcapsule and drying; and 3) crushing dried strain, and mixing with oligosaccharide and carrier. The present invention is one kind of high efficiency green feed additive.

Description

technical field [0001] The invention relates to a pollution-free high-efficiency oligosaccharide high-yield enzyme compound animal micro-ecological preparation and a preparation method thereof. Background technique [0002] Feed microbial additive is a new type of feed additive developed in the 1990s. Because it has advantages that antibiotics do not have in terms of disease prevention, improvement of feed conversion rate, and promotion of animal growth and production performance, it has been paid more and more attention. As the first-generation product to replace antibiotics, prebiotics have played a good role in overcoming the side effects of antibiotics and promoting animal growth and production performance, but there are still many shortcomings in a single prebiotic. First, the eugenic effect of the probiotics in the digestive tract of animals makes it difficult for live bacteria to colonize, complete regeneration or multiply in large quantities in a short period of time...

Problems solved by technology

As the first-generation product to replace antibiotics, probiotics have played a good role in overcoming the side effects of antibiotics and promoting animal growth and production performance, but there are still many shortcomings in a single prebiotic

First, the eugenic effect of the probiotics in the digestive tract of animals makes it difficult for live bacteria to colonize, complete regeneration or multiply in large quantities in a short period of time, so that the number of probiotics attached and colonized in the intestinal tract of animals is limited

Second, the dominance of probiotics in the gut of animals and the limitation of nutrients in the gut affect the application effect of probiotics

Because live bacterial preparations have their own specific micro-ecological environment, if they cannot supply the nutrients of exogenous live bacterial preparations in the intestinal tract for a long time, it will also die and fail

Third, the ability to produce enzymes is not high, which limits the effect of probiotics

However, experiments have shown that when the temperature is above 65°C, a large number of probiotics will be killed, and at the same time, adverse environments such as acid, alkali, and oxygen will also cause the inactivation of probiotics.

The above deficiencies directly affect the function of probiotics, making their effects insufficient and stable, and their effects are still subject to many restrictions.
