Fructooligosaccharides for Feed Industry

Application of Functional Oligosaccharide (Fructooligosaccharides FOS) in the feed Industry

Functional oligosaccharides is a growth factor of beneficial bacteria in the intestine, which can promote the balance of bacteria in animals. The functional oligosaccharides mainly include soybean oligosaccharides, fructooligosaccharides, mannose oligosaccharides, xylose, raffinose, Gold candy and so on.
In the area of feed, its low residue, non-drug resistance, innate nature and good diarrhea-reducing properties make it an alternative to antibiotics.

    The role of functional oligosaccharides and mechanism.

1) Beneficial flora: such as Bifidobacterium, Lactobacillus, which have a nourishing effect on animal body, can produce proteins, vitamin B, and Vitamin K.
It can make lactose into lactic acid, lactose to improve the Tolerance, while also promoting the absorption of calcium. And Bifidobacterium, Lactobacillus also has physiological functions, they can produce acetic acid, lactic acid, and other substances, reducing the intestinal pH, Escherichia coli is sensitive to acid, acidic environment can inhibit the proliferation of large intestine Salmonella, with the role of reducing diarrhea, And reduce the generation of harmful gases in animals.

2) Harmful bacteria: which can increase the toxic substances in animals and make the animals unwell or poisoned. In severe cases, they can cause large-scale infectious diseases. The representatives of flora are Escherichia coli, Staphylococcus, Pseudomonas and so on.

3) Intermediary bacteria: it bound in the community between beneficial and harmful bacteria, such as Peptococcus, Streptococcus, etc which are beneficial bacteria when they are in their health, but which become harmful bacteria when the body is in decline, sick and sub-healthy. Strains compete with each other in animals and inhibit each other to a state of homeostasis. In healthy state, beneficial bacteria prevail, while in the non-healthy state, harmful bacteria dominate.

Adding antibiotics can not only kill harmful bacteria, but also kill the beneficial bacteria, destroy the balance of intestinal flora, and add live bacteria that are subject to many conditions

2.functional oligosaccharides research.

Fructooligosaccharides are oligosaccharides that are combined into 1 to 3 fructose residues on the fructose residues of sucrose molecules, also known as fructo-oligosaccharides or oligofructoses, mainly found in bananas (0.3%), onions (2.8%), garlic (0.1%), rye (0.7%) and honey and other natural products.
    2) Physiological function:
A. can not be absorbed in the small intestine, and directly into the large intestine to promote the proliferation of beneficial bacteria such as Bifidobacteria.
B. prevent dental caries. Oligosaccharides can not be mutated streptococci as a fermentation substrate to generate insoluble glucan, does not provide oral microbial deposition, acid production and corrosion of the place.
C. promote animal growth.
D. prevent diarrhea.
E. enhance animal immune function, improve animal disease resistance.
F. Reduce the amount of ammonia and other corrupt substances in manure and manure.
    3)Application research:
Research on functional fructo-oligosaccharides, especially in the field of food and feed, has been widely carried out. A number of experimental results confirm the unique role of oligosaccharides. Fructo-oligosaccharides in Japan, the United States and Europe have been widely used as feed additives. Howard and other experiments in suckling pigs found that dietary supplementation of fructooligosaccharides, cecal, colonic mucosal cell proliferation faster than the control group, and to prevent colonic epithelial atrophy. Xiazhongsheng, an animal science and technology college of Guangxi University, added 0.2% and 0.5% fructooligosaccharides to the feed of weaned piglets. The results confirmed that fructooligosaccharides can improve the weaned piglets' weight gain and feed utilization efficiency.

The development and application of antibiotics makes animal intensive feeding possible, but the resulting side effects are also more and more recognized by people, the emergence of drug resistance, environmental pollution and residues from the animal body and then into the body caused by The impact of human health has always plagued people. Functional oligosaccharides will be a good alternative to antibiotics for their stable, low-sugar, non-toxic side effects, no contamination, no residue and their effect on good scavengers in the gut of animals.
