The Institute of Feeds, a part of
Zhejiang University, has recently announced that,
thanks to its more than one decade long study, it has
finally worked out a feed additive series at nanometer level
that is safe, highly efficient, and is of high quality.
The Institute has applied for two international
invention patents, as well as 6 national invention
patents.
A few years ago, the Institute
discovered four trace nutritional elements needed by both
humans and pigs. These elements have no harmful effects.
When being processed into nanometer grains, these
nutritional elements demonstrate apparently enhanced
physical properties in the form of a greatly increased
number of atoms on the grain surface. This in turn
remarkably increases their application efficiency.
Researchers have made the four trace nutritional elements
into an optimized combination together with a number of
other nutritional elements and turned it into a new and
fresh nanometer feed additive. In addition, the Institute
has developed other additives that are able to replace
antibiotics or absorb harmful and poisonous residues in
animal products. As a result, the Institute has created its
own unique animal nutriology.
The testing
results have shown that pork fed with the nanometer feed
additives only recorded 60% of the top limit for heavy metal
content as required by the EU. Thus, the additives have been
approved for applications in export—oriented pork production.
