Abstract
Nanotechnology is gaining more popularity in various applied fields due to
its versatile applications. Different world challenges, including pollution, resistance
against antibiotics, disorders in human/ animal digestive systems, contaminants of
feeds, health management & feed efficiency, etc., can be overcome by using
nanoparticles. Nanoparticles can be used as antibiotics, as feed additives, and can also
be used against mycotoxin and as biocidal agents. The efficiency and productivity of
various items could be improved using multiple supplements like enzymes, yeast, plant
extracts, etc. Many efforts are going on to improve productivity and efficiency using
different supplements, such as yeast, enzymes, probiotics, and plant extracts.
Nanomaterials can effectively replace all. In this chapter, we will discuss various types
of metal/metal oxide nanoparticles and their role in livestock as feed additives, pointing
out their level of toxicity as well. The current and future regarding the permissible
nanomaterials to be used in veterinary-related products will also be highlighted.
