This document discusses the potential for supplementing livestock with nanominerals. It begins by defining nanotechnology and nanoparticles. Nanoparticles are classified and their properties explained, including higher bioavailability than conventional minerals due to increased surface area. Methods for synthesizing and characterizing nanominerals are described, including physical, chemical and biological techniques. Applications of nanomineral supplementation in livestock are explored, including enhancing growth, immunity and reproduction. Some studies demonstrating benefits are highlighted. Finally, cytotoxicity concerns are raised and the need for safety assessment before wide application is noted.

2. Nanotechnology is defined as “utilization
of structure with at least one dimension
of nanometer (nm) size for the
construction of materials, devices or
systems with novel or significantly
improved properties due to their
nanosize”

3. Nanoparticles are defined as particles with sizes
between 1 and 100 nm that show properties that
are not found in bulk samples of the same material
(Auffan et al., 2009).
It found in Nano scale range between 10 -7
to 10 -9
Nanoparticles are entities some billionths of a meter in
size.
Nanoparticles can be both natural and man-made
entities, and are widely found in the environment.

5. Essentially having a particle size of 1-
100 nm.
At this scale, the physical, chemical, and
biological properties of materials differ
fundamentally and often unexpectedly.
The Nano-sized mineral particles are
having higher potential than their
conventional sources and thus reduce the
quantity required.

8. The bioavailability of Nanominerals is higher than any
other conventional mineral source.
Nano minerals improve bioavailability due to increase
in the surface area.
(Rajendran et al., 2013)
It can be affected by a number of factors including
animal species, physiological status, previous
nutrition, solubility of mineral element, interactions
with dietary nutrients and between minerals.

11. The values of particle size should not be confused
with crystalline size, as determined from XRD.
Here, crystalline size refers to set of atoms are
arranged in a particular way; which is periodically
repeated in three dimensions on a lattice. Whereas
particle size may and may not.

12. The crystalline size or grain size in
nanominerals can be determined with
several techniques that rely upon the peak
width in x-ray differentiation (XRD)
patterns.

16. The major differences between conventional ball
milling and the HEBM include:
The impact energy of HEBM is typically 1000 times
higher than the conventional ball-milling energy.
The dominant events in the conventional ball milling
i.e. particle fracturing and size reductions, which
correspond to actually, only the first stage of the HEBM.
The HEBM requires the controls of milling atmosphere
and temperature which are crucial to create the desired
structural changes or chemical reactions.

18. Biosynthesis of nanoparticles is a bottom-up technique.
microbial enzymes or plant phytochemicals with antioxidant
or reducing properties are used.
Green nanoparticles have been synthesized using various
plant species such as Avena sativa, Azadirachta indica, Aloe
vera, Alfalfa, papaya fruit extract, lemongrass, Sesbania
drummondii, latex of Jatropha cutcas (Shankar et al., 2004).
However, Microorganisms such as bacteria, actinomycetes,
yeast and fungi are also used for synthesis.

As particle size decreases, some metal-based
nanoparticles are showing increased toxicity,
even if the same material is relatively inert in its
bulk form (e.g., Ag, Au, and Cu).
nanoparticles also interact with proteins and
enzymes within mammalian cells.

27. In general biological methods are safe to use and can be
efficiently exploited without further experiment on residual
effect.
Studies so far have indicated that the application of nano
minerals in animal production, immunity and reproduction is
promising.
Application of nano-minerals is immense but the safety in
application of nanominerals needs to be assessed before it
being applied in the livestock industry.
