1.What is the merit of low-moleuclar-weight (LWM) chitosan compared to antibiotics?

Antibiotics is allowed to use in animal feed in many countries, it can prevent the propagation of harmful microorganisms in intestinal tract, but also prevent the breeding of beneficial microbial at the same time. The use of antibiotics can enhance the production of pigs, poultry or aquatic species. However, LMW chitosan prevents the progation of harmful microorganisms but enhances the breeding of benefical microbial, since chitosan is a type of cationic natural polymer. In addition, LWM chitosan is environmental friendly but antibiotics does harm to environment.
2.What is the difference between low-moleuclar-weight (LWM) chitosan and oligo-chitosan?
As indicated in its name, the moleular weight of LMW chitosan is higher than oligo-chitosan. Oligo-chitosan is water soluble and easy to absorb moisture from air, but LWM chitosan is water insoluble and very stable in air over a long time. Though water soluble LMW chitosan is also available by dissolving in acidic solution and then drying. More importantly, LMW chitosan has better antibacterial effect than oligo-chitosan.
3.What is the merit of low-moleuclar-weight (LWM) chitosan compared to oligo-xylose?
Both LMW chitosan and oligo-xylose can ehance the immunity of animal and used as feed additive. However, LMW chitosan has antibacterial effect but oligo-xylose does not, because chitosan has cationic amine groups in its macromolecular chains. As confirmed in our many tests, a combination use of LMW chitosan and oligo-chitosan is also a good choice.
4.What effect of low-moleuclar-weight (LWM) chitosan is expected for piglets?
The most significant effect is the reduction in the rate of diarrhea, which is a popular disease for piglet or pigling. It also enhances the growing of piglet. This has been demonstrated widely by plants or companies over China.
5.  What effect of low-moleuclar-weight (LWM) chitosan is expected for sow?
The use of LMW chitosan can start for sow after pregnacy of 80-90 days until the weaning of pigling. It will make sow and piglet more healthy and reduc the death rate of pigling. 
6.  What effect of low-moleuclar-weight (LWM) chitosan is expected for medium and big pig?
The most obvious effect is the enhancement of weight gain and immunity of medium and big pig. In addition, quality and flavor of pork can be also improved.
7. What effect of low-moleuclar-weight (LWM) chitosan is expected for poultry?
 It can enhance the immunity and weight gain of poultry and reduce the death rate of little chicken. In addition, it will also improve the flavor of chicken.
8. How to use and mix low-moleuclar-weight (LWM) chitosan in animal feed? 
Since the dose of LMW chitosan required for animal is very small, a good way of mixing is important. Normally, a pre-mixing step is recommended with other additives.
LMW chitosan can be used together with other additives, antibiotics, probiotics, etc., a synergistic effect may be expected.
