Various principles of microbial fermentation
The microbial fermentation feed is a kind of green biological feed, which not only enlarges the source of feed, but also improves the utilization rate of the feed. Moreover, the fermented feed contains a lot of beneficial microorganisms, which can well improve the animal's digestive system and improve the body's immunity. The production of fermented feed is the result of the action of microorganisms. When applied to production, the microorganisms in the feed and their metabolites also play an important role. Therefore, the fermentation effect and the use effect of fermented feeds are the key factors. So how do you choose the strain of fermented feed? Here's a brief introduction to the principles of selection of fermentative strains, the types of fermenting strains, and the Golden Baby Series Fermenters.
1. Selection principles of fermenting bacteria
The bacterial species used in the fermentation feed should have the following characteristics. 1) It is highly adaptable to the environment and has a great effect on the feed ingredients to be processed. Because currently fermented feeds on the market are generally raw materials, the fermented strains must compete with the microorganisms on the feed materials, and they quickly occupy an advantage. Therefore, strains used for fermentation are more adaptable and can grow better on fermentation raw materials. Reproduction. 2) The bacterial cells and metabolites have no side effects on animals without toxicity. Fermentation feeds are used directly or in combination with animal production, and their own or their metabolic products are toxic and harmful strains and cannot be used for feed fermentation. 3) Stability is not easy to mutate and no antagonistic effect on other strains. We know that the stability of strains determines whether the quality of the fermented feed is stable, while the fermentation effect of the compound multi-bacterial strains is better than that of a single strain, but the premise is that there is no antagonism between the combined strains. Antagonism will only Weaken the activities and effects of various strains.
2. Types of fermentation bacteria
In the "Category of Feed Additives" No. 2045 issued by the Ministry of Agriculture of China in December 2013, microorganisms that can be added to the feed include: Bacillus licheniformis, Bacillus subtilis, Bifidobacterium bifidum, Enterococcus faecalis, Enterococcus faecium Lactobacillus enterococci, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus genus Lactobacillus (Lactobacillus lactis), Lactobacillus plantarum, Pediococcus acidi, Pediococcus pentosaceus, Candida utilis, Saccharomyces cerevisiae Rhodopseudomonas, Bifidobacterium infantis, Bifidobacterium longum, Bifidobacterium breve, Bifidobacterium adolescentis, Streptococcus thermophilus, Lactobacillus reuteri, Bifidobacterium animalis, Aspergillus niger, Aspergillus oryzae, delayed spores Bacillus, Bacillus pumilus, Lactobacillus celloulis, Lactobacillus fermentum, Lactobacillus delbrueckii bulgaricus (Lactobacillus bulgaricus). Silage-producing Propionibacterium proponii, Lactobacillus plantarum and Lactobacillus paracasei can also be added to silage. At present, the types of microorganisms used for feed fermentation in the market are mostly compound inoculants such as lactic acid bacteria, Bacillus and yeasts.
3. Golden Baby Feed Starter
Because the nutrients and digestible utilization of different raw materials are different, and the ability and focus of different types of bacteria to decompose each nutrient component is different, so the selection of fermentative feed strains must be combined with the characteristics of raw materials. Jinbao starter series includes type II feeds, bean dregs, glutinous water, silages and other feed starters. It is based on the characteristics of different raw materials and combines lactic acid bacteria, bacillus, and yeasts in different types and proportions. The strains of the Golden Baby series starter are strains that can be added by the state and have no harmful effects on feeds and livestock. After being optimized for cultivation, their activity and stability are strengthened, and the quality of the feed can be more effectively improved and the economic benefit can be improved. .
